Microglial activation involves metabolic reprogramming characterized by a shift from oxidative phosphorylation to aerobic glycolysis via HIF1α stabilization. This 'glycolytic switch' provides rapid ATP for phagocytic machinery and reprograms gene expression toward pro-inflammatory cytokine production. Glycolytic microglia exhibit enhanced C1QA and C3 transcription and accelerated pruning. The Domain Expert cut this due to insufficient mechanistic specificity and translation obstacles.
**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
