Non-hydrolyzed disaccharides accumulate within lysosomes due to resistance to lysosomal hydrolases, creating osmotic gradients that disrupt lysosomal membrane integrity and inhibit V-ATPase proton pumps. This prevents mTORC1 recruitment to lysosomal surfaces, enabling TFEB nuclear translocation. However, melibiose is hydrolyzed by α-galactosidase (activity in motoneurons unconfirmed), and other non-hydrolyzable disaccharides (sucrose, raffinose, cellobiose) do not produce equivalent autophagy, i
**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
