In the Four Core Genotype mouse model of Th17-driven progressive CNS autoimmunity, male gonadal hormones reduce disease severity via Wnt/{beta}-catenin, while XY chromosomes worsen Th17 pathogenicity.
- Why it matters: Sex hormones and sex chromosomes jointly shape autoimmune outcomes, but their interaction in Th17-mediated progressive CNS disease is not well resolved.
- What they did: Using FCG mice to separate hormones from chromosomes, the study tested how gonadal hormone exposure and XY versus XX complement affect Th17 phenotype and disease, identifying SUV39H1 and Runx2 as regulators.
- The result: Male hormones promote a homeostatic, non-pathogenic Th17 program, XY complement exacerbates pathogenicity in a recipient sex-dependent manner, and hormonally and chromosomally female FCG Th17 cells induce more severe disease than WT females, implicating parental imprinting.
