Astrocyte-derived TGF-β1 engages microglial TGFBRII/TGFBRI complex, activating SMAD2/3 corepressor complexes that displace RelA/p300 coactivators at NF-κB-dependent promoters (TNF, IL1B, IL6). This mechanism rewires trained microglia to a homeostatic state by disrupting epigenetic memory at inflammatory gene enhancers. Supported by landmark ALS and Parkinson's disease studies showing TGF-β-driven anti-inflammatory microglial phenotypes.
