What molecular mechanisms link PICALM SNPs to altered APP endocytosis and Aβ generation?

OPEN

The abstract establishes that PICALM SNPs are associated with Alzheimer's disease and that PICALM regulates APP internalization, but the mechanistic connection between genetic variants and functional changes remains unexplained. Understanding this link is critical for translating GWAS findings into therapeutic targets. Gap type: unexplained_observation Source paper: Role of phosphatidylinositol clathrin assembly lymphoid-myeloid leukemia (PICALM) in intracellular amyloid precursor protein (APP) processing and amyloid plaque pathogenesis.
