For decades, Marcus Peter, PhD, has drilled into an area of research focused on cell death and the roles of toxic and protective short RNAs, with the goal of developing a novel form of cancer treatment. Now, this same line of research has led Peter's team to uncover new insights into the cause of Alzheimer's disease. In this episode, Peter explains his pioneering work in investigating RNA interference in diseases and explains how his lab's latest novel discovery may have relevance to an array of neurodegenerative diseases beyond Alzheimer's.
