Microglial cells may hold key to Alzheimer's plaque removal

Immune cells in the brain called microglia can partially break down large amyloid plaques characteristic of Alzheimer's disease by latching on to them, forming a sort of external stomach and releasing digestive enzymes into the space, according to a preclinical study by Weill Cornell Medicine investigators.
