X-Linked KDM6A Escapes X-Inactivation to Drive Female-Biased Microglial Neuroprotective States in Early AD
🧪 Overview
The histone demethylase KDM6A, which escapes X-inactivation, drives higher H3K27me3 demethylation activity in female microglia than in male microglia. This results in elevated expression of neuroprotective microglial gene programs (homeostatic and disease-associated microglia transition states) in early AD. KDM6A-driven sex differences in microglial states explain the paradox of higher female AD prevalence despite relative microglial protection: female-biased microglial activity compensates initially but ultimately fails at later disease stages.
