Global DNA hypomethylation in atherosclerotic VSMCs leads to demethylation of CpG sites in the P2RY12 promoter, increasing chromatin accessibility and transcription factor binding. However, the specificity problem is severe—global hypomethylation affects thousands of genes, and methylation changes in plaques may reflect proliferative history rather than active regulatory mechanisms driving P2RY12 expression.
**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
