“Blocking protein’s activity restores cognition in old mice”

Brain cells called microglia serve as the brain’s garbage crew, scarfing up bits of cellular debris. But their underperformance in aging brains contributes to neurodegeneration. Now, a possible workaround?

By blocking a protein’s activity with antibodies, Stanford University School of Medicine investigators were able to improve cognitive behavior in aging mice.

A paper describing the finding was published online April 3 in Nature. Tony Wyss-Coray, PhD, professor of neurology and neurological sciences, is the senior author. The lead author is MD-PhD student John Pluvinage.

Wyss-Coray has been working for several years on the question of what causes the brain to lose its acuity with advancing age. One focus of his research has been a class of brain cells called microglia, which serve both as the brain’s immune cells and its garbage crew. Among the many different things microglia do to keep the brain healthy is scarfing up bits of cellular debris and protein deposits that build up in the course of normal metabolic activity.

NOMIS awardee Karl Deisseroth elected to the National Academy of Engineering

The National Academy of Engineering has announced today that Karl Deisseroth, the D. H. Chen Professor of Bioengineering and of Psychiatry and Behavioral Science, will be one of their newly elected members.

Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer.  Academy membership honors those who have made outstanding contributions to “engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature” and to “the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education.”

NOMIS Foundation announces recipients of 2019 Distinguished Scientist and Scholar Award

We are delighted to announce the three new recipients of the 2019 Distinguished Scientist and Scholar Award — congratulations to Adriano Aguzzi, Janet Currie and Antonio Rangel.

Recognizing their outstanding contributions to the advancement of science and human progress through their pioneering, innovative and collaborative research, the NOMIS Award is enabling their continued investigation into the fundamental mechanisms of neurodegeneration (Aguzzi), the use of big data to identify better therapies for children with mental disorders (Currie), and the neurocomputational basis of simple decision making across species (Rangel).

NOMIS Awards are presented to pioneering scientists and scholars who, through their innovative, groundbreaking research, have made a significant contribution to their respective fields. Their bold ideas and unique approaches involve interdisciplinary collaboration and apply a broad range of methods, building bridges across the boundaries of disciplines.

The awardees

Adriano Aguzzi

Adriano Aguzzi is professor and director of the Institute of Neuropathology at the University of Zurich in Zurich, Switzerland. He has dedicated most of his professional life to understanding the molecular basis of prion diseases, combining transgenetics with molecular and immunological techniques. He clarified the crucial steps in the pathogenesis of the disease, discovered the cells and molecules involved in prion neuroinvasion, and elucidated the mechanisms leading to brain damage in these diseases. Aguzzi’s discoveries are enabling novel approaches to the diagnosis, prophylaxis and therapy of prion diseases and other neurodegenerative disorders. His NOMIS-supported research project is titled: Exploring the Locales of Cognitive Decline: Cellular and Molecular 3D Atlases of Brain Pathology in Aging and in Neurodegeneration.

Janet Currie

Janet Currie is the Henry Putnam Professor of Economics and Public Affairs at Princeton University’s Woodrow Wilson School of Public and International Affairs in Princeton, NJ, United States. Currie’s research focuses on health and wellbeing, particularly of children. She addresses socioeconomic differences in health and access to health care, environmental threats to health, and mental health. Currie co-directs Princeton’s Center for Health and Wellbeing and the Program on Children at the National Bureau of Economic Research. She is the recipient of numerous awards and honors, including the Carolyn Shaw Bell Award for furthering the status of women in the economics profession, and honorary doctorates from the University of Zurich and the University of Lyon. Her NOMIS-supported research project is titled: Harnessing Big Data to Improve Children’s Mental Health Treatment.

Antonio Rangel

Antonio Rangel is the Bing Professor of Neuroscience, Behavioral Biology, and Economics, and Head Faculty in Residence at the California Institute of Technology (Caltech) in Pasadena, CA, United States. Rangel studies the computational and neurobiological basis of human decision making, employing a variety of tools from neuroscience, economics, psychology and computer science, including functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and transcranial magnetic stimulation (TMS), among others. His NOMIS-supported research project is titled: Using Triangulation to Characterize the Neurocomputational Basis of Simple Choice.

Tony Wyss-Coray’s research highlighted in New Scientist article “Young people’s blood is being tested as a treatment for Parkinson’s”

Blood from young adults is being trialled as a treatment for Parkinson’s disease by a firm that wants to use the therapy to target neurodegenerative conditions.

Alkahest, a firm co-founded by Tony Wyss-Coray of Stanford University, California, has already tested blood-based treatments in people with Alzheimer’s disease. In the latest trial, 90 people with Parkinson’s – mostly in their 70s and 80s – will receive injections five days in a row, and then again three months later.

Svante Pääbo cited in Forbes’ “Four Biggest New Things We Learned About Human Evolution In 2018”

2018 was a banner year for discoveries about our species’s evolution and extinct relatives like the Neanderthals. Here are the biggest finds, sorted according to how they fit into our evolutionary story.

The Little Foot skeleton may be an unrecognised species

Little Foot is a near-complete skeleton of an Australopithecus, a kind of hominin that lived in Africa between 2 and 4 million years ago. Ronald Clarke of the University of the Witwatersrand in Johannesburg, South Africa found the skeleton in Sterkfontein cave in the 1990s and has spent 20 years meticulously excavating it. The first detailed analyses finally came out in late November. Little Foot was an elderly female who seems to have sustained an arm injury in her youth. She ate an almost entirely vegetarian diet.

SRF: “Genome crime scene: from Neandertal to superhumans?”

In China, the first genetically modified babies are said to have seen the light of day. This once-taboo act shows how far genetic engineering can revolutionize life on the planet. Swiss radio and television company SRF’s Wolfram Eilenberger interviewed NOMIS awardee and paleogeneticist Svante Pääbo and bioethicist Effy Vayena in the Sternstunde Philosophie (Great moments in philosophy) program “Tatort Genom: Vom Neandertaler zum Übermenschen?” (“Genome crime scene: from Neandertal to superhumans?”).

No field of knowledge has achieved greater progress in recent decades than human genetics. The questions involved are at the heart of our way of life: Which genes are specific to humans? How much Neandertal is still in us? Which forms of diagnosis and healing promise new techniques and intervention options? Are we on the cusp of a new, genetically optimized superhuman? Together with Vayena and Pääbo, Eilenberger discusses the limits, dangers and utopian possibilities of human genetics. The program is presented in German.

Pääbo is director of the Department of Evolutionary Genetics at the Max Planck Institute in Leipzig, Germany and recipient of the 2017 NOMIS Distinguished Scientist Award. He is one of the founders of paleogenetics and became best known for his pioneering research on the Neandertal genome. Pääbo is investigating the genetic differences and functional consequences that occurred at the split between the modern human and their archaic human ancestors about half a million years ago.
