DeepSummary
In this podcast episode, biomedical researcher Sonia Vallabh shares her personal story of discovering she had inherited the genetic mutation for a rare and fatal prion disease. She explains how this news led her and her husband Eric to dedicate their lives to finding a cure, leaving their careers to pursue PhDs in biological sciences and eventually leading a research lab at the Broad Institute focused on developing preventative therapies for prion diseases.
Vallabh discusses the unique challenges of prion diseases, where a normal protein in the body misfolds and triggers a cascade of neurodegeneration. She emphasizes the importance of preventing the disease rather than just treating symptoms, which requires a different approach than traditional clinical trials. Her team is working to find drugs that can deplete the prion protein before it becomes pathogenic.
Throughout her journey, Vallabh has gained a deeper appreciation for the fragility and mystery of the human brain. She reflects on living with the uncertainty of her genetic risk, cherishing her role as a mother, and finding grace amidst life's challenges. Her quest is driven by a sense of urgency to protect the irreplaceable gift of human cognition.
Key Episodes Takeaways
- Sonia Vallabh is a biomedical researcher leading efforts to find a preventative cure for the fatal prion disease she is genetically predisposed to.
- Prion diseases are caused by the misfolding of normal proteins in the brain, triggering a cascade of neurodegeneration.
- Vallabh's approach focuses on depleting the prion protein before it becomes pathogenic, rather than treating late-stage disease.
- Her quest has been deeply shaped by the personal impact of losing her mother to prion disease and inheriting the same mutation.
- Vallabh emphasizes the importance of preserving and honoring the fragile gift of human cognition.
- Her work illustrates the value of prevention over treatment for certain diseases affecting the brain.
- Vallabh finds meaning and resilience in embracing life's challenges while recognizing the uncertainty of her genetic risk.
- Her dedication comes from a sense of urgency to develop an optimal preventative therapy within her lifetime.

- “What if we can do the most good. Not by going after the big scary pathogens and lobbing fireballs at them, but instead by doing something much more understated and subtle and less sexy and less conventional.“ by Sonia Vallabh

Biomedical researcher Sonia Vallabh's life was turned upside down when she learned she had the genetic mutation for a rare and fatal illness, prion disease, that could strike at any time. Thirteen years later, her search for a cure has led to new insights about how to catch and prevent disease — and how to honor our grandest, most mysterious inheritance: our brains.
