Loss of the miR-143/145 cluster during VSMC phenotypic switching derepresses transcriptional regulators (KLF4, Myocardin) that activate P2RY12, or alternatively, disease-specific miRNA targeting of P2RY12 3'UTR is lost. While highly novel and testable via dual-luciferase assays, the dual-mechanism hedge undermines falsifiability and the pathway requires multiple unproven intermediates for the indirect transcriptional model.
**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
