Pro-inflammatory cytokine TNF-α activates NF-κB signaling in VSMCs, binding to κB sites in the P2RY12 promoter and amplifying a feed-forward inflammatory loop that drives foam cell formation in advanced atherosclerosis. The mechanistic precedent from platelet studies and the potential for local vascular delivery of IKKβ inhibitors provide the most tractable translational path, though direct promoter binding in VSMCs requires validation.
**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
