Incomplete hypothesis (truncated). ApoE4 isoform from astrocytes fails to mediate proper cholesterol efflux from microglia, maintaining pathological trained immunity states. Loss of ApoE4 function leads to cholesterol accumulation in microglial lipid rafts, stabilizing NF-κB complexes and perpetuating inflammatory memory.
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.
