Trehalose induces Hsp70 and BAG3 expression, redirecting chaperone activity from inhibiting autophagy receptors toward maintaining lysosomal membrane integrity and preventing cytochrome c release. BAG3 simultaneously promotes autophagosome-lysosome fusion while inhibiting apoptosis initiation. Temporal mismatch between transcription and acute protection is the critical weakness.
**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
