Structurally diverse disaccharides activate autophagy through independent, parallel mechanisms that converge on TFEB: trehalose via V-ATPase/mTORC1 inhibition, melibiose via partial α-galactosidase substrate action generating signaling metabolites, and lactulose via non-cell-autonomous effects (if systemic) or alternative stress pathways. This explains why individual knockdown of any single pathway does not fully block disaccharide effects, while global outcomes remain similar. Requires comprehe
**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
