Simone Biles And Valuing Mental Health, Mask And Vaccine Guidance, Child Tax Credit Options: Today’s Top Stories – NPR

Posted: August 2, 2021 at 1:42 am

Simone Biles, the greatest gymnast of all time, will not compete in the individual all-around gymnastics final at the Tokyo Olympics on Thursday.

Biles is the defending champion for the sport's marquee individual event. She won by a huge margin at the 2016 games in Rio de Janeiro.

The announcement comes after she pulled out of the team final after a rocky opening vault on Tuesday, saying she needed to take care of her mental health.

"I've just never felt like this going into a competition before," she said. "I tried to go out here and have fun ... but once I came out here, I was like, 'no, the mental is not there, so I just need to let the girls do it and focus on myself.' "

USA Gymnastics was supportive of her decision to withdraw from Thursday's event and applauded "her bravery in prioritizing her well-being" in a statement. "Her courage shows, yet again, why she is a role model for so many," the organization added.

Jade Carey, who came to Tokyo as an event specialist, will take Biles' place in the all-around individual event. The 21-year-old had an exceptionally strong showing at the qualifying event, placing ninth overall. However, she was not chosen as a member of the U.S.' four-person team and did not compete in the team event on Tuesday after Biles' withdrawal.

The announcement does not mean this is the last we'll see of Biles; she could still compete in the individual event finals. USA Gymnastics said she'd be evaluated every day to determine whether she'll take part. She qualified in all four of the events.

Biles is one of several Olympic athletes garnering praise and support after speaking openly about the stress of the Games and the importance of prioritizing mental health others include legendary American swimmer Katie Ledecky and Japanese tennis star Naomi Osaka.

As Mandalit del Barco reports from Tokyo, Olympic organizers and Team USA brought mental health resources for athletes and staff in an especially stressful year.

"Besides the pressure to be the best, and besides the global pandemic, there's also the fact there are no spectators allowed to watch the Games in person," she explains. "There aren't any family members to hug after they win, there are no friends or family or fans to cheer them on from the stands."

Stress affects all of us, even if we're not Olympic athletes. Here are some more resources and suggested reading:

Advanced Therapy Medicinal Products and Next-Gen Vaccine Production – Genetic Engineering & Biotechnology News

Posted: at 1:42 am

Advanced therapy medicinal products (ATMPs) are a focus for biopharma. The ability to treat disease in a targeted manner, the reduced likelihood of competition, and regulatory support make such products attractive R&D targets.

The revenue potential of ATMPs is another factor. Estimates suggest the global market for ATMPs could grow to $9.6 billion by 2026.

But for the market to reach its full potential, industry must find efficient ways of making ATMPs, according to Maria Papathanasiou, PhD, assistant professor, Imperial College Londons department of chemical engineering, who says mathematical modeling is key.

Mathematical models and/or computer modeling tools can assist decisions throughout drug development from discovery all the way to therapy distribution, she says. In manufacturing, such tools can help with decision making related to selection of units, optimization of processes, identification of optimal conditions of operation, and they can also be used as soft sensors when measurements are not readily available.

For Papathanasiou, the key benefit of building a mathematic model is that it allows for the systematic analysis of the system considering multiple factors at the same time.

The impact of synergetic/antagonistic effects can be better studied. Also, they provide a cost-efficient basis for in silico experimentation, decreasing the time and labor required for wet lab experiments, she tells GEN. Such tools give us the ability to run a very high number of experiments on the computer and then decide which of those we want to validate in the lab. They have a great potential to assist with initiatives such as Quality-by-Design and Design Space Identification as well.

Models can also be used on the factory floor, Papathanasiou says, explaining they prove to be a very powerful tool for in-process monitoring and online control as validated models can be used as soft sensors when online measurements are not readily available.

Papathanasiou, who co-authored a recent study examining the role modeling can play in process development for ATMPs and next-generation vaccines, says choosing the correct type of model on which to base process development is a critical step.

Such models can be mechanistic, data-driven, or hybrid. Each class of models is different with mechanistic models being the most detailed in terms of translating the physicochemical characteristics of the system into mathematical equations (each variable and parameter reflects an actual entity of the system at hand), she explains. Data-driven models sit at the other end where they use input/output datasets to capture the system dynamics, without the need to know what is exactly going on in terms of physicochemical properties, reactions, etc.

Choice of model is important as each require different types of data and process monitoring technology required.

Depending on the class of models one uses the amount of data differs. In our collaborations with companies, we use primarily existing or offline data for the development of such tools and the current analytics tie in nicely, she continues. For an online implementation of such tools that are also known as digital twins advanced PAT would really advance the usability.

ByGina Wadas

Viruses are experts at infiltrating the body, as the SARS-CoV-2 virus (and resulting COVID-19 pandemic) have amply demonstrated. But their efficiency in targeting specific and isolated cells also make them useful drug delivery vehicles, known as viral vectors.

Viral vectors are modified viruses that can act as couriers to transport therapeutic "packages" to specific diseased cells. These packages contain instructions with modified or designed DNA or RNA to correct or supplement a faulty or missing gene. For instance, the Johnson & Johnson COVID-19 vaccine uses viral vectors to transport modified genetic material from the SARS-CoV-2 virus to cells, generating an immune response.

Though viral vector-based gene therapies are among the most advanced treatments for many congenital and acquired diseases, producing them is complex and costly.

"One of the major challenges in viral vector gene therapy is how to improve the quality, purity, and cost of the manufactured viral vectors, so that we can use the smallest possible effective dose, reduce immune side effects, and lower the cost of treatments," said Hai-Quan Mao, associate director and core faculty member of the Institute for NanoBioTechnology. He is also a professor in the departments of Materials Science and Engineering and Biomedical Engineering and a core faculty member at the Translational Tissue Engineering Center.

Hai-Quan Mao

Associate director, Institute for NanoBioTechnology

To address this challenge, Mao and his team are teaming up with Nolan Sutherland, senior scientist at bluebird bio, a Cambridge, Massachusetts-based biotechnology company that develops gene therapies. The partnership started about two years ago when Yizong Hu, a biomedical engineering PhD student under the mentorship of Mao, was at an annual meeting for the American Society for Gene and Cell Therapy presenting his research on a new particle assembly technology. Sutherland heard the presentation and approached Hu to discuss the technology and its application to the production of lentiviral vectors, which are made from a family of viruses that infect people by reverse transcription of their RNA into DNA in their host cells' genome.

Sutherland thought that the Mao team's approach might help streamline transfection, a key step in producing viral vectors. During transfection, a polymer solution is combined with a mixture of DNA plasmids to form transfection particles, a cumbersome procedure involving complicated solution blending and strictly timed dosing.

Mao, Hu, and Yining Zhu, also a biomedical engineering PhD student, developed a more effective and shelf-stable formulation of DNA particles in a ready-to-dose form. They also discovered that size-controlled sub-micron particles are most effective in transfecting cells and producing viral vectors. This production method is based on the team's years of experience in controlling transfection vehicle characteristics to enhance performances and stability.

The team members validated their findings with Sutherland at bluebird bio using that company's bioreactor. They compared the new method with the industry standard, and the results showed improved vector production yield, shelf stability, handling stability, and quality control of the transfection process.

"With the drastic increase in demand for lentiviral vector-based cell therapy products ... this new technology will greatly improve the production quality, consistency, and yield of our therapeutic LVVs," Sutherland said.

The team reported its findings in Nano Letters and is scaling up production with an eye to transferring the technology to the marketplace.

"This work represents a great example how we can partner with corporate collaborators to accelerate the translation of discoveries on the bench to the industry. This type of collaboration with industry provides us opportunities to identify the technical gaps in the engineering solutions that we develop, and fine tune them to better address the real-world problems in a more targeted fashion," Mao said.

According to Sutherland, the partnership with Mao and his team has "allowed bluebird to pursue high risk/reward innovation in a space outside of its core expertise. The team has a keen eye for application to industry which has made the partnership incredibly productive."

Team members say that this new particle engineering technology will find a wide range of applications in the manufacture of a variety of viral vectors for gene and cell therapy applications.

Also contributing to the project are Jordan Green, professor in the Department of Biomedical Engineering and associate member at the INBT, and Sashank Reddy, assistant professor of plastic and reconstructive surgery at Johns Hopkins Medicine, medical director at Johns Hopkins Technology Ventures, and affiliate faculty member at the INBT.

Decrease in Neurotransmitter Release Found in Neurons Derived from People with Schizophrenia and a Rare Genetic Mutation – UMass News and Media…

Posted: at 12:59 pm

AMHERST, Mass. A scientific team has shown that the release of neurotransmitters in the brain is impaired in patients with schizophrenia who have a rare, single-gene mutation known to predispose people to a range of neurodevelopmental disorders.

Significantly, the results from the research with human-derived neurons validated previous and new experiments that found the same major decrease in neurotransmitter release and synaptic signaling in genetically engineered human neurons with the same genetic variant the deletion of neurexin 1 (NRXN1). NRXN1 is a protein-coding gene at the synapse, a cellular junction that connects two nerve cells to communicate efficiently.

Both the research with human-derived and engineered human neurons also found an increase in the levels of CASK, an NRXN1-binding protein, which were associated with changes in gene expression.

Losing one copy of this neurexin 1 gene somehow contributes to the etiology or the disease mechanism in these schizophrenia patients, says molecular neuroscientist ChangHui Pak, assistant professor of biochemistry and molecular biology at the University of Massachusetts Amherst and lead author of the research published in the Proceedings of the National Academy of Sciences. It causes a deficit in neural communication.

Pak is quick to add that although this single-gene mutation puts people at risk for schizophrenia, autism, Tourette syndrome and other neuropsychiatric disorders, at the end of the day, we dont know what causes schizophrenia. This variant gives us insight into what cellular pathways would be perturbed among people with schizophrenia and a lead to study this biology.

When she conducted most of the research, Pak was working in the Stanford University lab of Thomas Sdhof, a neuroscientist who shared the 2013 Nobel Prize in Physiology or Medicine for helping to lay the molecular basis for brain chemistry, including neurotransmitter release.

The research team obtained cell specimens from schizophrenia patients with an NRXN1 deletion who donated samples to a national biorepository for genetic studies of psychiatric disorders. Pak and colleagues converted the participants specimens into stem cells and then turned them into functional neurons to study. Were rewinding these cells back, almost like a time machine what did these patients brains look like early on, Pak explains.

Labs at Stanford, Rutgers University and FUJIFILM Cellular Dynamics were independently involved in the generation and analysis of neurons. For comparison with the human-derived neurons, Pak and team also created human neurons from embryonic stem cells, engineering them to have one less copy of the NRXN1 gene. With engineered human neurons, they had previously noted the neurotransmitter impairment and were interested in whether they would have the same findings with patient-derived neurons.

It was good to see the consistent biological finding that indeed the neurexin 1 deletion in these patients actually does mess up their neuronal synaptic communication, and secondly that this is reproducible across different sites whoever does the experiment, Pak says.

Notably, the researchers did not see the same decrease in neurotransmitter release and other effects in engineered mouse neurons with analogous NRXN1 deletion. What this suggests is there is a human-specific component to this phenotype. The human neurons are particularly vulnerable to this genetic insult, compared to other organisms, adding to the value of studying human mutations in human cellular systems, Pak says.

Being able to reproduce the results is key to the development of drugs that can better treat schizophrenia. Everything was done blindly and at different sites. We wanted to not only learn about the biology but also be at the top of our game to ensure rigor and reproducibility of these findings, Pak says. We showed the field how this can be done.

Pak and her team are now continuing the research in the Pak Lab, supported by a five-year, $2.25 million grant from the National Institute of Mental Health. The scientists are using the latest stem cell and neuroscience methodologies to explore the molecular basis of synaptic dysfunction in schizophrenia and other neuropsychiatric disorders.

Research Shows Non-Genetic Tumor Diverseness Contributes to Treatment Failure in Cancer Patients – University of Arkansas Newswire

Posted: at 12:59 pm

The figure above summarizes the findings of the team in terms of genetic, epigenetic and stochastic differences among the EGFR-mutant lung cancer cells studied.

Leonard Harris, assistant professor of biomedical engineering, led a team of researchers from Vanderbilt Universitythat has shown how an in vitro model of tumor heterogeneity, or diversity, resolves three different sources of cell state variability in cancer cells.

The paper has been published in PLOS Biology, part of the Public Library of Science.

A heterogeneous tumor is a tumor that is made up of many different types of cancer cells. Often, the cells have different types of genetic mutations and co-exist within a tumor. The diversity of the tumor is what makes cancer difficult to treat.

"It's like the success of a diverse team," Harris explains. "A team made up of people from different backgrounds, ages, stages of their career, etc., are often better at tackling problems because the team members provide different perspectives."

In a tumor, different cells respond to drug treatments differently. Some cells are able to survive and regrow the tumor and spread, which is why Harris and his team continue to research the ways surviving cancer cells differ from the other tumor cells.

But genetic mutations are not the only way cancer cells can differ from each other. Cells that have the exact same DNA can exist in very different states. For example, your skin cells and your liver cells have exactly the same DNA but they function very differently; that is an example of epigenetic heterogeneity. Moreover, when a skin cell divides, it produces two skin cells. The cells do not inherit the skin cell state from the DNA; it has to come through some other means. It is this non-genetic form of inheritance that makes the process epigenetic.

Cancer cells also differ due to random fluctuations in molecule numbers inside each cell: molecules randomly interact with each other, degrade, are synthesized by the cell, secrete into and out of the cell, etc. This type of non-genetic heterogeneity is called stochastic variability and is not heritable, unlike epigenetic processes. It might not seem like a big deal, but researchers have shown that stochastic variability can have major effects.

The experimental and computational work reported in the paper was performed at Vanderbilt University in collaboration with Corey E. Hayford, Darren R. Tyson, C. Jack Robbins III, Peter L. Frick and Vito Quaranta and has motivated many additional research projects. It is now the foundation for Harris' U of A laboratory.

"Cancer is commonly referred to as a 'genetic disease', meaning it is caused by mutations in critical parts of the DNA that cause cells to grow out of control," Harris said. "This has led to decades of research on the genetics of cancer, which has resulted in significant advances, including the development of numerous therapeutic drugs that target so-called 'driver oncogenes.' While exceptionally effective in the short term, these targeted drugs fail almost universally, with patient tumors recurring within a few months to a few years. This has led many researchers to begin considering the role of non-genetic processes in the response of tumors to drugs."

Modeling and experimental techniques were used to distinguish the three different sources of variability among lung cancer cells: genetic, epigenetic and stochastic. As stated above, epigenetic and stochastic variabilities are different types of non-genetic variability. Epigenetically distinct cells look different, like the skin and liver cells from the example above, whereas stochastically distinct cells appear nearly identical but may act completely different.

"Distinguishing genetic from non-genetic, and epigenetic from stochastic, factors in drug response is crucial for developing new therapies that can kill tumor cells before they have a chance to acquire genetic resistance mutations," Harris said. "They all contribute to tumor drug response in different ways."

A framework for distinguishing genetic and non-genetic sources of heterogeneity in tumors has been proposed previously but is not yet widely accepted within the cancer research community because of a lack of strong experimental evidence. The team's paper provides strong support for this framework.

The analysis presented in the paper was applied specifically to EGFR-mutant non-small cell lung cancer. Harris' lab is currently applying these ideas to other cancer types as well, including small cell lung cancer, melanoma and bone-metastatic breast cancer.

"In my laboratory, we are working on building computational models of the molecular networks within cancer cells that give rise to the different epigenetic states, across which cells can transition to survive drug treatments," Harris said. "The long-term goal of my lab's research is to expand these models until they are of sufficient detail to act as virtual platforms for testing the effects of various drugs and identifying novel drug targets."

By constructing these so-called "digital twins," the hope is to one day use them to perform virtual drug screens on models built from samples of real patient tumors and then design personalized treatment options for those patients. This will require forming collaborations with bioinformaticians, experimentalists and clinicians here at U of A, the Winthrop P. Rockefeller Cancer Institute at the University of Arkansas for Medical Sciencesin Little Rock, and elsewhere. "Hopefully, the publication of this paper will help spark some of those collaborations," Harris said.

About the Public Library of Science: The Public Library of Science states on its website, "PLOS Biology empowers authors to publish the full arc of their research without compromising quality. Researchers can more fully and accurately represent their science and get credit for all their work."

Fate Therapeutics to Host Virtual Event Highlighting Interim Phase 1 Clinical Data from its Off-the-Shelf, iPSC-derived NK Cell Franchise for B-cell…

Posted: at 12:58 pm

SAN DIEGO, July 16, 2021 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer, today announced that management will host a virtual event to highlight interim Phase 1 clinical data from its FT596 and FT516 programs for the treatment of relapsed / refractory B-cell lymphomas on August 19, 2021 at 4:30 p.m. ET.

The live webcast of the presentation can be accessed under "Events & Presentations" in the Investors section of the Company's website at http://www.fatetherapeutics.com. The archived webcast will be available on the Company's website beginning approximately two hours after the event.

About Fate Therapeutics iPSC Product PlatformThe Companys proprietary induced pluripotent stem cell (iPSC) product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that can be administered with multiple doses to deliver more effective pharmacologic activity, including in combination with other cancer treatments. Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Companys first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event and selecting a single engineered iPSC for maintenance as a clonal master iPSC line. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, clonal master iPSC lines are a renewable source for manufacturing cell therapy products which are well-defined and uniform in composition, can be mass produced at significant scale in a cost-effective manner, and can be delivered off-the-shelf for patient treatment. As a result, the Companys platform is uniquely capable of overcoming numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells, which is logistically complex and expensive and is subject to batch-to-batch and cell-to-cell variability that can affect clinical safety and efficacy. Fate Therapeutics iPSC product platform is supported by an intellectual property portfolio of over 350 issued patents and 150 pending patent applications.

Story continues

About FT516FT516 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line engineered to express a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor, which has been modified to prevent its down-regulation and to enhance its binding to tumor-targeting antibodies. CD16 mediates antibody-dependent cellular cytotoxicity (ADCC), a potent anti-tumor mechanism by which NK cells recognize, bind and kill antibody-coated cancer cells. ADCC is dependent on NK cells maintaining stable and effective expression of CD16, which has been shown to undergo considerable down-regulation in cancer patients. In addition, CD16 occurs in two variants, 158V or 158F, that elicit high or low binding affinity, respectively, to the Fc domain of IgG1 antibodies. Numerous clinical studies with FDA-approved tumor-targeting antibodies, including rituximab, trastuzumab and cetuximab, have demonstrated that patients homozygous for the 158V variant, which is present in only about 15% of patients, have improved clinical outcomes. FT516 is being investigated in a multi-dose Phase 1 clinical trial as a monotherapy for the treatment of acute myeloid leukemia and in combination with CD20-targeted monoclonal antibodies for the treatment of advanced B-cell lymphoma (NCT04023071). Additionally, FT516 is being investigated in a multi-dose Phase 1 clinical trial in combination with avelumab for the treatment of advanced solid tumor resistant to anti-PDL1 checkpoint inhibitor therapy (NCT04551885).

About FT596FT596 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line engineered with three anti-tumor functional modalities: a proprietary chimeric antigen receptor (CAR) optimized for NK cell biology that targets B-cell antigen CD19; a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor, which has been modified to prevent its down-regulation and to enhance its binding to tumor-targeting antibodies; and an IL-15 receptor fusion (IL-15RF) that augments NK cell activity. In preclinical studies of FT596, the Company has demonstrated that dual activation of the CAR19 and hnCD16 targeting receptors enhances cytotoxic activity, indicating that multi-antigen engagement may elicit a deeper and more durable response. Additionally, in a humanized mouse model of lymphoma, FT596 in combination with the anti-CD20 monoclonal antibody rituximab showed enhanced killing of tumor cells in vivo as compared to rituximab alone. FT596 is being investigated in a multi-center Phase 1 clinical trial for the treatment of relapsed / refractory B-cell lymphoma as a monotherapy and in combination with rituximab, and for the treatment of relapsed / refractory chronic lymphocytic leukemia (CLL) as a monotherapy and in combination with obinutuzumab (NCT04245722).

About Fate Therapeutics, Inc.Fate Therapeutics is a clinical-stage biopharmaceutical company dedicated to the development of first-in-class cellular immunotherapies for patients with cancer. The Company has established a leadership position in the clinical development and manufacture of universal, off-the-shelf cell products using its proprietary induced pluripotent stem cell (iPSC) product platform. The Companys immuno-oncology pipeline includes off-the-shelf, iPSC-derived natural killer (NK) cell and T-cell product candidates, which are designed to synergize with well-established cancer therapies, including immune checkpoint inhibitors and monoclonal antibodies, and to target tumor-associated antigens using chimeric antigen receptors (CARs).

Book Review: Lessons Learned From the Wayward Brain – Undark Magazine

Posted: at 12:58 pm

When someone close to you develops signs of mental illness, you spring into detective mode. You ask questions, but the answers seem vague and incomplete. You scour your memory for any years-old signs, any warnings that might have seemed innocuous in the moment but raise red flags in retrospect.

You wonder: If anyone had noticed then, would things be different now? And if they refuse to seek treatment, you think, it doesnt have to be this way if only you could figure out how to break through.

If this sounds familiar, you might be interested in Projections: A Story of Human Emotions by Karl Deisseroth and A Sense of Self: Memory, the Brain, and Who We Are by Veronica OKeane, two recent entrants in the vast arena of nonfiction books that explore both the biology of mental illness and how the brain works in general. Both authors use patient stories as conduits to talk about advancements in neuroscience, illuminating the brains various structures and the connections between them.

BOOK REVIEW Projections: A Story of Human Emotions, by Karl Deisseroth (Random House, 256 pages).

Patient narratives across both books show that not all who receive psychiatric treatment survive the storm in their minds, while others regain a sense of themselves that was lost. And though scientists may be inconceivably far away from revealing how a 3-pound fatty organ in the skull gives rise to all the complexities of mental life, at least the questions can be well posed, as Deisseroth puts it.

Deisseroth, a professor at Stanford University, is best known for developing new and influential technologies for studying the brain. But in this book he draws from his work as an emergency psychiatrist at a hospital in Silicon Valley, and explores how confronting people in crisis influenced the way he investigates the brain in both humans and animals, potentially laying the groundwork for future clinical treatments. It is enthralling to consider: the experiences of suffering human beings, and thoughts about mouse and fish brains, are informing each other, he writes.

Presenting a cast of characters encountered in the cramped, windowless Room Eight of the hospital, Deisseroth reflects on a broad swath of his psychiatry experiences, from his residency in the early 2000s to his more recent patient work. His book resembles a series of connected short stories interwoven with recent findings from research on the neural circuits that give rise to mental illness. At times it may feel like reading fiction because it partly is Deisseroth freely uses his imagination in his portrayal of patients and their inner lives. But he pulls these threads together with his own memoir-ish voice, revealing the struggles, frustrations, and triumphs of someone driven to understand both the cold science of the brain and the hot mess of the mind.

A man loses his pregnant wife in a car accident and doesnt know why he cant cry. A patent lawyer believes her neighbor has installed a satellite dish to channel her thoughts. After a breakup, a 19-year-old begins cutting his arms. Deisseroth ends up in a dramatic chase when a patient slips out of the exam room, only to find shed gone to binge-eat and vomit. Unlike Psychology 101 disease prototypes, these feel like real people. And while theyre actually projections, filtered through the lens of a doctor who fictionalizes details to protect patients privacy, they are vivid reminders that mental health can be a fragile, elusive thing.

But psychotherapy and imagination arent the only ways Deisseroth peers into the brain. Seeking answers to tough questions that have confounded psychiatrists for decades, Deisseroth helped pioneer a technology called optogenetics. Once patients leave the hospital, Deisseroth has no control over their behavior, let alone their brains. But with optogenetics, he and other researchers can turn on and off individual neural circuits, or even neurons themselves at least, in laboratory animals.

In optogenetics, researchers hijack genes called microbial opsins from bacteria and algae and encode them in the brain cells of lab animals mostly mice, rats, and fish. These exotic genes lead to the creation of proteins with a special power to convert light to electrical current. Normally, most neurons dont turn on in the presence of light (although a 2019 study questions that assumption). But as a result of this feat of genetic engineering, scientists can activate individual brain cells by delivering light to them. With unprecedented precision, they can then investigate how different parts of the brain participate in both typical behaviors and symptoms of mental illness.

It is enthralling to consider: the experiences of suffering human beings, and thoughts about mouse and fish brains, are informing each other, Deisseroth writes.

The impact of optogenetics has been far-reaching in revealing the brains inner workings, at least in animal models. And after more than 15 years of laboratory study, its potential is moving into the human realm. In May 2021, too recent to make it into this book, scientists reported in Nature Medicine that a blind patient regained partial vision as a result of optogenetic therapy.

But in terms of innovations in psychiatric patient care, what are the lessons from optogenetics? A lot of this work is still in its infancy. Deisseroth says his laboratory research informs the psychiatric patient care that he continues to give, yet many of the landmark studies are about causations and chemical pathways in genetically modified mice, not humans. Scientists can model eating disorders in rodents, but no one is talking about removing the skull flaps of people with anorexia, genetically modifying particular brain cells and zapping them with light to restart the drive to eat normally. Nor might it be that simple. Yet there is some hope that by understanding the fundamental mechanisms at work, new treatments could one day be developed.

One of the most direct feedback loops between Deisseroths hospital and lab work is a patient named Charles, who changed Deisseroths thinking about autism. Charles comes to Deisseroth as a young information technology specialist who, among other social impairments, consistently avoids eye contact. One morning, Deisseroth asks him what makes him look away. Charles tells him, It overloads the rest of me.

This introspection is so profound to Deisseroth that he says it justifies his entire career progression: All the extra years of both MD and Ph.D. training, all the pain and personal challenges of internship, all the call nights as a single father, worrying about my lonely son. This alone was enough.

While information overload seems like an abstract concept, it could be rooted in too much firing of excitatory cells, which stimulate other neurons, compared to inhibitory cells, which do the opposite. In 2011, Deisseroths team used optogenetics to increase the activity of excitatory cells in the prefrontal cortex of mice, which appeared to cause them to be less social with other mice. This part of the book is a bit technical, but the bottom line is that an imbalance in cellular activity could play a role in the asocial behaviors associated with autism.

Tantalizingly, it appears that this imbalance might be corrected. In 2017, Deisseroths team reversed social impairment in mice carrying genetic mutations associated with autism through opposite methods in the prefrontal cortex making inhibitory cells fire more, or lowering the activity in excitatory cells. In fact, such experiments suggest that social avoidance can be turned on or off in adult mice, a revelation that may generate new hope for future interventions in adult humans.

BOOK REVIEW A Sense of Self: Memory, the Brain, and Who We Are, by Veronica OKeane (W. W. Norton & Company, 288 pages).

Deisseroths most compelling narratives detail brief encounters with patients in vulnerable, distressing circumstances. Veronica OKeane, on the other hand, describes longer-term relationships with her patients in A Sense of Self: Memory, the Brain, and Who We Are although patient stories take more of a backseat to science in this book. She is a professor of psychiatry at Trinity College Dublin, and has been practicing for more than 30 years. Like all psychiatrists, as a patient once said to me, I am like a detective, she writes.

OKeane draws from her clinical experiences to offer a comprehensive tour of the current state of knowledge about how memory operates in the brain. Individuals with psychiatric illnesses have a great deal to tell neuroscience, and the larger world, about the processes involved in the organization of memory, she writes.

A Sense of Self at times reads like a textbook, complete with a few diagrams. Anyone who has read a neuroscience book previously will recognize H.M., who was famously unable to form new memories after undergoing brain surgery, as well as Phineas Gage, who was impaled with an iron rod and how the tragic circumstances of their impairments taught the fledging field of neuroscience a lot about what does what in the brain.

But what makes OKeanes book engaging is how she incorporates references to literature and folklore, putting a different spin on familiar stories like Lewis Carrolls Through the Looking- Glass, in which Alices adventures closely mimic feelings of psychosis.

Another is Charlotte Perkins Gilmans 1892 short story The Yellow Wallpaper, about a woman trapped in the wall of her bedroom. Its often portrayed as a tale of the oppression of women at that time, but OKeane has a different take: Its a perfect description of experience of what we now call postpartum psychosis, she writes.

Postpartum psychosis, a condition seldom spoken about, can make otherwise healthy new mothers lose sight of what is real and what is not. Perkins Gilman herself experienced postpartum psychosis, and years later, after her cancer treatments failed, ended her own life in 1935.

OKeane describes a patient, Edith, who developed delusions about her baby being an imposter, as well as her own husband. With the help of antipsychotic medications, Edith heals and comes back to reality. Yet she still feels terror when she sees the gravestone that she had believed to be the site of her babys burial the memories are real, she tells the author. This distinction set me on a long-term pathway of inquiry about the nature of the matter of memory, OKeane writes.

Some who suffer psychosis are so accustomed to the voices in their heads and other delusions that they decline medicine to make them go away. They feel scared to let go of their inner lives and participate in the same reality that others share.

Like much of life, mental health can be seen as a matter of achieving some kind of equilibrium. Everyone, psychotic or not, operates by balancing ones inner world full of thoughts, feelings, and memories with the external world and all of the stuff of society. If there is anything that I have learned from my work with mentally ill patients it is that the achievement of an easy equilibrium between oneself and the world is what determines ones happiness, OKeane writes.

As it happens, OKeane also briefly touches on innovations in optogenetics. She focuses on an experiment by Susumu Tonegawa using optogenetics to implant false memories in mice, which I covered as a CNN reporter in 2013. By genetically altering neurons and shining blue light on them, scientists made mice believe they had been shocked in one chamber, even though they were shocked in a different chamber. The mice eventually froze up in fear even when the researchers were not activating the memory in their brains.

OKeanes take on this research is that artificial modification of memory is fascinating, but that in some sense the mouse memories arent false because the neural matter of the experience is formed regardless. Just as Edith regarded her hallucinations about her babys death as real memories, these mice have real memories of something that never occurred. Edith brought home to me how memory is, in essence, neurally coded experience, OKeane writes.

As we go about our lives, according to OKeane, we tag experiences with emotions, which are then triggered later as we are reminded of them, but we never re-live them in quite the same way. Is there ever a boundaried memory untouched by the present, like a walled cement garden? she writes. The answer in her view is decidedly no, for each time we recall a moment, it is colored by who we have become since it happened.

If there is anything that I have learned from my work with mentally ill patients it is that the achievement of an easy equilibrium between oneself and the world is what determines ones happiness, OKeane writes.

OKeanes book will be useful for anyone looking for a deep dive into how memory works, but it is not as much of a page-turner as Projections. Still, I was moved by both authors concerns for their patients and acknowledgement that science has only scratched the surface of learning how psychiatric illness works at a fundamental level in the brain. The double-edged sword here is that you are not alone, but also, no one really understands.

Yet, there is hope. The stories in both works reveal a range of humanity that is barely understood by people who devote their lives to the study of mental illness and is often stigmatized by those who do not. They are in some sense thank-you notes to the patients who have taught the authors about the nature of the brain and given them more to investigate in the future.

And while a person battling with delusions of paranoia may seem far removed from academic papers on genetically engineered mice, both authors argue that the gap between laboratory insights and clinical practice is narrowing. As this science develops, psychiatric illness will become a major target of investigation, and I believe this will be the beginning of the ending of the stigmatization of psychiatric illness, OKeane writes.

An important caveat here, she adds, is that most of my patients do not feel similarly optimistic.

With $172 Million Raise, Wugen Brings Natural Killer Therapies to Solid Tumors Next – BioSpace

Posted: at 12:58 pm

The NK program has taken off with multiple indications. According to Dan Kemp, its lead product, WU-NK-101, is already proving itself in an ongoing Phase I/II trial, demonstrating an "impressive complete response rate in relapsed/refractory AML." It's the promising results of these memory NK cells drivingthis week's announcementof a $172 million Series B raise.

Company founder John McKearntold BioSpacein January that Wugen "started as a twinkle in his eye" to bring a durable, allogeneic CAR-T therapy on the market. At that time, the biotech's natural killer (NK) cell program was a recent addition to its core focus on CAR-T therapy.

A potential clincher is that Wugen also believes its memory NK cell platform can go where CAR-T treatments have thus far failed solid tumors.

According toresearchfrom Wugen co-founder Todd Fehniger and his team at Washington University School of Medicine, memory NK cells respond better than normal NK cells against cancers. By being primed in the lab before being administered to the patient, they're more potent in vivo at attacking cancer, even in melanoma, where immunotherapies have seen just a 50% response rate.

By using an allogeneic approach, where the cells come from healthy donors instead of the patient, the treatments would be readily available "off-the-shelf," improving access and lowering costs. With Wugen's technology, a single donation can create hundreds of individual therapies.

NK-based therapy also gets a leg up on CAR-T in that NK cells do not trigger a cytokine storm.

"Our Memory NK cells don't require any genetic engineering to be potent cancer cell killers, and we've demonstrated this effectively in AML patients, with none of the toxic side effects that are commonly seen with CAR-T cell therapies. We've also developed a proprietary process that enables us to scale up the manufacturing so we can produce a commercially viable off-the-shelf product," Kemp told BioSpace.

Cytokine storm is a prevalent side effect in CAR-T cell recipients. An overresponse by the immune system caused by the release of cytokines by the CAR T cells can lead to widespread organ dysfunction.

Kemp took over as founding CEO McKearn transitioned to the board in April. Kemp's resume boasts decades of experience in pharma and biotech, with his most recent role heading up Takeda's cell therapies. A perfect match for spearheading Wugen's rapidly advancing cell therapies.

Just before Kemp came on, Wugeninked a dealwith Shanghai's Alpha Biopharma to commercialize its off-the-shelf cell products in Asia.

Funds from the Series B raise will go into propelling the memory NK platform, advancing the current program for severe AML, and take its other indications to their next steps both as monotherapies and in combination with antibody drugs - head & neck cancer, melanoma and solid tumors. Wugen's CD7-targeting CAR-T cell therapy will also advance for the treatment of T-cell leukemia and lymphoma.

"We are gearing up for a Wugen-sponsored multi-site open-label Phase I/II study of WU-NK-101 in AML, which is slated to open early 2022. Trials of WU-NK-101 in solid tumors will follow later in 2022," Kemp said.

He accredits their rapid success in the field of immunotherapies to his predecessor: "It's important to recognize that the solid foundation that we're benefiting from now with this financing event was carefully and skillfully built by John McKearn over the past 2-3 years."

UC Santa Barbara chemical engineering professor Michelle OMalley has been named the recipient of the American Institute of Chemical Engineers (AIChE) 2021 Allan P. Colburn Award. The award, named for a legendary professor who founded the University of Delaware chemical engineering department, recognizes significant contributions to chemical engineering through publications by younger members of the institute. Nominees must have earned their highest academic degree within 12 calendar years of the year in which the award is presented. OMalley received her Ph.D. in chemical engineering from the University of Delaware in 2010.

I'm honored to be recognized with the Allan P. Colburn Award from AIChE, OMalley said. This honor inspires me to reflect on all of the wonderful publications that originated from my laboratory many of which came from very risky research projects that took many years to bring to fruition. I attribute the Colburn Award to the hard work and dedication of current and past trainees in my laboratory, as well as several key collaborators who conducted the research and worked with me to publish these studies.

In 2020 alone, OMalley received an AIChE Food, Pharmaceutical, and Bioengineering Division Early Career Award, as well as an American Society of Microbiology Award for Early Career Applied and Biotech Research, and was named a fellow of the American Institute of Medical and Biological Engineering. She has received a Camille Dreyfus Teacher-Scholar Award and a Rising Star Award from the American Chemical Societys Women Chemist Committee, among many other honors and distinctions.

We at the College of Engineering are tremendously proud of Professor Michelle OMalley, said Rod Alferness, dean of engineering. Her innovative research, published regularly in high-profile journals, has earned her broad respect and recognition, as well as numerous professional awards, the latest of which is the prestigious Allan P. Colburn Award. Her work reflects the spirit of multidisciplinary collaboration that characterizes the College of Engineering and enables so many important discoveries to emerge. I offer her our deepest and most sincere congratulations.

On behalf of the chemical engineering department, we congratulate Professor OMalley on this well-deserved recognition, said Rachel Segalman, department chair. The Colburn Award is the most prestigious award for early-career chemical engineers given by our national disciplinary society, AIChE, and is a reflection of Michelles innovation and insightful contributions to the field. Were thrilled for her and to have her as part of our community.

OMalley received a U.S. Department of Energy Early Career Award in 2013, a TechConnect Innovation Award in 2014 and a National Science Foundation Early Career Award in 2015. She earned a Presidential Early Career Award for Scientists and Engineers (PECASE) from President Obama in 2016, the highest distinction bestowed on young scientists by the federal government. She has been named one of the Top 35 Innovators Under 35 by the MIT Technology Review, and was included in the 2019 Science News list of Ten Scientists to Watch.

OMalley is perhaps best known for establishing a new research field by engineering anaerobes, which evolved to decompose and recycle carbon biomass throughout the Earth from our guts to landfills and compost piles. She is the world leader in engineering anaerobic fungi and associated microbiomes and has published papers on various aspects of the subject in many leading journals, including Science, Nature Microbiology, Nature Genetics, and Nature Chemistry.

Her long-term vision is to achieve a fundamental understanding of the genetic pathways that will lead us to understand and control biomass breakdown in anaerobic microbiomes, which has applications in carbon cycling, bioremediation and the production of high-value chemicals.

OMalleys group has provided breakthrough insights into enzymes that already outperform the current industrial standards, and also multiplied the amount of sequencing data available for anaerobic fungi. They developed the first standard laboratory practices to work with these fragile organisms, and made discoveries about biomass-degrading enzymes that had eluded the community for several decades. Her innovative approaches and results are generating substantial attention not only from the scientific community, funding agencies and industry, but also from the popular press, including BBC News, Newsweek, CNBC News and Forbes.

By leveraging breakthroughs made in her lab such as isolating anaerobes from the guts and fecal materials of herbivores and identifying a very large extracellular non-catalytic scaffolding protein in fungi that mediates enzyme tethering and biomass hydrolysis she established a set of design rules (a parts list) to make synthetic enzyme complexes having new properties and functions.

OMalleys ongoing work focuses on the fact that biomass digestion is generally performed by consortia of microbes; she is now developing systems-level tools to evaluate and direct microbial interactions. She and her students have recently pioneered new approaches to isolate not only fungi, but also their dependent bacteria and methanogens, to create a simplified system to model their interactions. Her groups research set the foundation for engineering microbial interactions in anaerobes to accelerate biomass breakdown, and serves as a unique spring board to study and engineer how microbes partner in nature and in bioreactors.

Her most recent publication describes how anaerobic fungi contain the genetic building blocks for putative antibiotics, opening the possibility depending on what further characterization research shows for the development of new medicines from gut microbes.
