Integrative SEA-AD analysis reveals coordinated failure of tripartite synapse maintenance, where neuronal synaptic gene downregulation correlates with astrocyte phagocytic receptor upregulation and microglial synaptic pruning gene alterations. Complement cascade (C1Q, C3) and TAM receptors (MERTK, AXL) represent crosstalk nodes. However, 'tripartite synapse' is a conceptual model, transcriptional correlations do not establish functional crosstalk, and C1q/C3 roles are context-dependent with uncl
**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
