Structurally diverse disaccharides trigger a general nutrient stress response via unidentified membrane sensors, elevating cAMP and activating PKA. PKA phosphorylates CREB and activates CRTC2, which drives TFEB transcriptional coactivation. Major weaknesses: cAMP elevation evidence is from yeast (PMID: 17607311), lactulose's SCFA mechanism requires gut bacteria (irrelevant to cultured neurons), and PKA canonically INHIBITS autophagy via ULK1 phosphorylation at Ser757 (PMID: 22948138), contradict
**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
