Trehalose-induced LMP preferentially releases lysosomal Ca2+ through mucolipin-1 (TRPML1) channels, creating localized Ca2+ microdomains with sustained kinetics that selectively activate calcineurin over CaMK family members. Calcineurin exhibits high affinity for sustained Ca2+/calmodulin signals and may be spatially enriched near lysosomal membranes via AKAP proteins or direct TRPML1 interaction. However, channel redundancy (TPC1-3, TRPML1-3) remains an unresolved confounding variable requiring
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
