How does PICALM specifically regulate the endosomal trafficking of APP to amyloidogenic processing sites?

OPEN

While the study shows PICALM affects APP internalization and Aβ production, the precise molecular mechanisms governing how PICALM directs APP to specific endosomal compartments where β- and γ-secretases cleave APP remain unclear. This mechanistic gap limits understanding of how to modulate this pathway therapeutically.
