The triggering receptor expressed on myeloid cells 2 (TREM2) gene is associated with the pathogenesis of LOAD and plays important roles in mediating the phagocytosis of Aβ by microglia and regulating inflammation in central nervous system.
This gene-based, transethnic approach identified PINX1, a gene involved in telomere integrity, and TREM2, a gene with a product of an immune receptor found in microglia, as associated with LOAD.
In this review we discuss our current knowledge of the risk genes APOE4, BIN1, CD2AP, PICALM, PLD3 and TREM2 and their impact on endolysosomal (dys)regulations in the light of late-onset Alzheimer's disease pathology.
Variants in the triggering receptor expressed on myeloid cells 2 (TREM2) have been associated with increased risk for sporadic, late-onset Alzheimer's disease.
