Trehalose induces selective lysosomal permeabilization releasing Ca²⁺ without complete cathepsin efflux. Lysosomal Ca²⁺ release activates calcineurin, leading to TFEB nuclear translocation and autophagy gene transcription, while insufficient cytosolic cathepsin activity fails to trigger apoptotic cascades. Primary weakness is the uncharacterized mechanism for selectivity.
**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
