  • CNS Neurons That Actually Regenerate Throughout Life

    CNS Neurons That Actually Regenerate Throughout Life
    May 17 2025
    In this eye-opening episode of The Neuron Regeneration Podcast, we explore the remarkable regenerative power of olfactory neurons—and what that could mean for healing damage in the central nervous system. Host Jarod Carter is joined by Claudia Garrigós (PhD student) and Jaume Lillo (postdoctoral researcher), two scientists from the University of Barcelona who are authors on a fascinating review paper titled: Olfactory receptors in neural regeneration in the central nervous system. While neurons in the brain and spinal cord typically don't regenerate after injury, olfactory neurons do—and they do so throughout adulthood. This unique biological process may hold critical clues for repairing various forms of neurotrauma or neurodegenerative diseases. Claudia and Jaume share insights from their research into how olfactory receptor cells regenerate, why olfactory glial cells are already being used in preclinical trials for spinal cord repair, and what challenges remain in translating this science into real-world therapies. They also offer personal reflections on the most surprising discoveries from their research—and even trace the evolutionary origins of the sense of smell back 700 million years. This episode is a must-listen for anyone interested in regenerative neuroscience, and the untapped potential of the body's own sensory systems. Please note, at the time of this writing, Claudia is looking for a 3 month research exchange program with a US-based lab during her PhD.

  • Redefining Parkinson's Treatment: Dr. Jonathan Sackner-Bernstein on a Novel Approach to Treatment and Disease Reversal

    Redefining Parkinson's Treatment: Dr. Jonathan Sackner-Bernstein on a Novel Approach to Treatment and Disease Reversal
    Feb 28 2025

    In this insightful episode of the Neuron Regeneration Podcast, we explore a groundbreaking new perspective on Parkinson's disease treatment. Dr. Jonathan Sackner-Bernstein, a physician, engineer, and former FDA and DARPA leader, challenges the long-held belief that Parkinson's is solely a disease of dopamine deficiency.

    Instead, his research suggests that excess dopamine inside neurons may be a key driver of the disease—an insight soon-to-be-tested in human clinical trials with a repurposed drug that could potentially stop Parkinson's progression.

    Dr. Sackner-Bernstein shares his journey from cardiology to neuroscience, how personal experience led him to question conventional wisdom, and why breaking out of silos in research is key to advancing new treatments.

    Key Topics Discussed:

    • Rethinking Parkinson's Disease:
      Why the prevailing dopamine deficiency model may be incomplete—and how shifting our understanding could transform treatment.

    • From Discovery to Clinical Trials:
      How a repurposed drug, already FDA-approved for other uses, will soon being tested for its potential to stop or even reverse Parkinson's disease.

    • The Challenge of Scientific Dogma:
      What it takes to challenge long-standing medical assumptions and gain acceptance for new ideas in the scientific community.

    • Cross-Disciplinary Innovation:
      How expertise in cardiology, drug development, and regulatory science informed Dr. Sackner-Bernstein's unique approach to Parkinson's research.

    • Funding and the Future of Repurposed Drugs:
      Why securing investment for repurposed drugs is difficult, and how strategic patenting can help ensure their viability as new treatments for new indications.

    • The Power of "First Principles" Thinking:
      How revisiting the fundamental assumptions of a disease can unlock new therapeutic possibilities.
