Discovered infectious proteins that rewrote neuroscience dogma
"The result of these investigations is the absolute conviction that infections by prions cause neurodegeneration."
Biography
Stanley Prusiner revolutionized understanding of neurodegenerative diseases by discovering prions—misfolded proteins that cause infection without DNA or RNA. His controversial theory, initially rejected by the scientific establishment, earned him the 1997 Nobel Prize in Physiology or Medicine and fundamentally changed how we understand mad cow disease, CreutzfeldtJakob disease, and Alzheimer's.
Key Facts
- Won the Nobel Prize in 1997 for discovering prions, challenging the central dogma that all infectious agents contain nucleic acids
- His work explained mad cow disease (BSE) transmission through contaminated meat, preventing a potential public health catastrophe
- Faced fierce skepticism for years; his prion hypothesis was called 'heretical' by establishment neuroscientists
- Directed the Institute for Neurodegenerative Diseases at UCSF, advancing prion disease research globally
- Demonstrated that prions cause disease through self-propagating protein misfolding, opening new therapeutic avenues
Proteins that infect without genes? Nobel Prize winner proved them real.
