In this Medical Forum, Arthur Horwich '73, '75 M.D. and recipient of a 2011 Alpert and Mary Lasker Award for Basic Medical Research, will deliver the Ruth B. Sauber Distinguished Medical Alumni Lecture. Horowich will discuss the basic nature of protein folding in the cell, as an assisted process, and how its failure in specific instances leads to neurodegeneration or other diseases. Horwich and his team have discovered that such misfolding can have profound implications for diseases like Alzheimer's. An informal reception will follow the presentation. This event begins at 11 a.m. in Smith-Buonanno Hall, Room 106. http://brown.edu/about/commencement/about/commencement-reunion-forums
