Material below is adapted from the SfN Short Course TREM2 Variants: New Keys to Decipher Alzheimer’s Disease Pathogenesis, by Marco Colonna, MD, and Yaming Wang, PhD. Short Courses are day-long scientific trainings on emerging neuroscience topics and research techniques held the day before SfN’s annual meeting.
