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.
