Biochemist Suzanne Pfeffer is an expert on the molecular roots of Parkinson’s disease. Her work focuses on mutated proteins linked to Parkinson’s risk. She’s discovered, for instance, that drugs inhibiting one of the proteins can help neurons regrow primary cilia and stave off cell death, reversing disease progression. Since similar drugs are in clinical trials, her findings bring great hope for people with a subtype of Parkinson’s and hopefully can be linked to earlier detection through warning signs like REM sleep disruptions and loss of smell. “This is precision medicine,” Pfeffer tells host Russ Altman of the future of Parkinson’s disease on this episode of Stanford Engineering’s The Future of Everything podcast.
