In this episode, Eric Verdin, CEO of the Buck Institute, and Stanford University’s Dr. Tony Wyss-Coray discuss the groundbreaking science of brain rejuvenation through heterochronic parabiosis, a process where young blood factors are shown to restore cognitive function and potentially extend lifespan. Moving from the lab to the clinic, they explore the next frontier: Proteomic Clocks. By measuring thousands of proteins, scientists can now determine the biological age of individual organs, allowing for the detection of Alzheimer’s and other neurodegenerative diseases up to 15 years before symptoms appear. This shift toward high-precision organ tracking marks a new era in preventative geroscience and personalized longevity.

Tony Wyss-Coray is a Professor of Neurology and Neurological Sciences and the Director of the Phil and Penny Knight Initiative for Brain Resilience at Stanford University. His lab studies brain aging and neurodegeneration with a focus on age-related cognitive decline and Alzheimer’s disease. The Wyss-Coray research team discovered that circulatory blood factors can modulate brain structure and function and factors from young organisms can rejuvenate old brains. Current studies focus on the molecular basis of the systemic communication with the brain by employing a combination of genetic, cell biology, and –omics approaches in killifish, mice, and humans. Wyss-Coray has presented his ideas at Global TED, the Tencent WE Summit, and the World Economic Forum. He co-founded Alkahest Inc. and several other companies targeting Alzheimer’s and neurodegeneration and has been the recipient of an NIH Director’s Pioneer Award, a Zenith Award from the Alzheimer’s Association, and a NOMIS Foundation Award.
