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.

Few people have as much experience with patient care and long-term research as the celebrated geriatrician and epidemiologist Luigi Ferrucci. Listen in as he speaks with Gordon about his journey from acute care to population studies, the effective design of clinical trials, and moving towards predictive medicine so we can use our natural resilience to maintain health as we age.

Dr. Luigi Ferrucci is a geriatrician and an epidemiologist who conducts research on the causal pathways leading to progressive physical and cognitive decline in older persons. In September 2002, he became the Chief of the Longitudinal Studies Section at NIA and the Director of the Baltimore Longitudinal Study on Aging. Dr. Ferrucci received a Medical Degree and Board Certification in 1980, a Board Certification in Geriatrics in 1982 and Ph.D. in Biology and Pathophysiology of Aging in 1998 at the University of Florence, Italy. Between 1985 and 2002 he was Chief of Geriatric Rehabilitation at the Department of Geriatric Medicine and Director of the Laboratory of Clinical Epidemiology at the Italian National Institute of Aging. During the same period, he collaborated with the NIA Laboratory of Epidemiology, Demography, and Biometry where he spent several periods as Visiting Scientist at NIH. Dr. Ferrucci has made major contributions in the design of many epidemiological studies conducted in the U.S. and in Europe, including the AKEA study of Centenarians in Sardinia and the Women's Health and Aging Study. He was also the Principal Investigator of the InCHIANTI study, a longitudinal study conducted in the Chianti Geographical area (Tuscany, Italy) looking at risk factors for mobility disability in older persons. In 2002, Dr. Ferrucci refined the design of the Baltimore Longitudinal Study of Aging to focus on the Geroscience Hypothesis, which states the pace of biological aging is the root cause of many age-related chronic diseases, as well as physical and cognitive disability. He has made major contributions to the literature and is one of the most cited scientists in the field of aging. Dr. Ferrucci has been Scientific Director at NIA since May 2011.

The movement to integrate longevity treatments into clinical care is making strides. How can we ensure they are evidence-based, accessible, and personalized? World-renowned geroscientist Andrea Maier has been leading the way with innovative clinical trials and cutting edge research.

Our chronological age doesn’t tell us much about how well our bodies are aging, but scientists have developed many ways to measure changes at the cellular and molecular levels, including the rate of change, that can suggest ways to improve health at every stage of life. Follow along as Gordon speaks with Daniel Belsky of Columbia University about DNA methylation, the effects of famine and poverty on aging biology, studying the exposome, and how to create equitable access to potential aging interventions.

Dr. Belsky is an Associate Professor of Epidemiology in the Robert N. Butler Columbia Aging Center at Columbia University. His studies seek to understand how genes and environments combine to shape health across the life course. The goal of Dan's work is to reduce social inequalities in aging outcomes in the US and elsewhere. With collaborators Terrie Moffitt and Avshalom Caspi he originated the Pace of Aging method to quantify the aging process from longitudinal analysis of human physiology and recently translated this method into a DNA-methylation blood test that can be implemented from a single time point of data collection. He is principal investigator of NIH-funded projects to test how caloric restriction may slow or reverse aging-related changes to the genome (CALERIE), to understand long-term impacts of in-utero famine exposure on biological aging (Dutch Hunger Winter Family Study, with Bertie Lumey), and to test the potential of anti-poverty policy intervention to slow biological aging (MyGoals for Healthy Aging, with Peter Muennig). Dan's work has received international attention, including by the Wall Street Journal, Washington Post, and Guardian newspapers, and appeared in outlets including PNAS, Nature Human Behaviour, Nature Aging, the JAMA journals, Lancet Respiratory Medicine, and top journals in epidemiology and gerontology. Since 2020, he has been named an ISI highly-cited researcher.

Of all the biochemical changes that occur with aging, what really matters? How can we use the incredible amount of health data available today to discover the best targets for interventions? In this episode, Kristen Fortney of BioAge talks with Gordon about the latest research in proteomics and metabolomics, the importance of muscle loss, and the challenge of measuring the right endpoints for effective treatment and regulatory approval.

Kristen Fortney is the co-founder and CEO of BioAge, a clinical-stage biotechnology company developing a pipeline of treatments to extend healthy lifespan by targeting the molecular causes of aging. The company uses its discovery platform, which combines quantitative analysis of proprietary longitudinal human samples with detailed health records tracking individuals over the lifespan, to map out the key molecular pathways that impact healthy human longevity. By targeting these pathways with a large and mechanistically diverse portfolio of drugs, BioAge is unlocking opportunities to treat and prevent diseases of aging in entirely new ways. Kristen’s scientific background is in aging biology and bioinformatics. She received her PhD in Medical Biophysics from the University of Toronto, followed by postdoctoral training at Stanford University, where she was a fellow of the Ellison Medical Foundation & American Federation for Aging Research.

What is the relationship between diet, chronic disease, and aging? Can we delay or reverse the effects of aging at the cellular level by following a fasting-mimicking diet? Listen in as Gordon speaks with Valter Longo of the Longevity Institute at USC about epigenetic reprogramming, turning on Yamanaka factors, and restoring our cells to a youthful state based on over 30 years of research on diet and fasting.

Dr. Valter Longo is the Edna M. Jones Professor of Gerontology and Biological Sciences and Director of the Longevity Institute at the University of Southern California –Leonard Davis School of Gerontology, Los Angeles, one of the leading centers for research on aging and age-related disease. Dr. Longo is also the Director of the Longevity and Cancer Program at the IFOM Institute of Molecular Oncology in Milan, Italy. His studies focus on the fundamental mechanisms of aging in simple organisms and mice and on how these mechanisms can be translated to humans. The Longo laboratory recently published key findings on a 5 day periodic dietary intervention called Fasting Mimicking Diet (FMD), and showed in randomized clinical trials that FMD reduces the risk factors and markers associated with aging and diseases. Dr. Longo’s most recent studies focus on the use of FMD interventions to activate stem cell- based regeneration to promote longevity. He is the author of The Longevity Diet.
