Impaired estrogen signaling underlies regulatory T cell loss-of-function in the chronically inflamed intestine.

ABSTRACT: Signaling of 17β-estradiol (estrogen) through its two nuclear receptors, α and β (ERα, ERβ), is an important mechanism of transcriptional regulation. Although ERs are broadly expressed by cells of the immune system, the mechanisms by which they modulate immune responses remain poorly understood. ERβ-specific signaling is reduced in patients with chronic inflammatory diseases, including systemic lupus erythematosus and inflammatory bowel disease, and our previous work suggests that dysregulation of ERβ-specific signaling contributes to enhanced intestinal inflammation in female SAMP/YitFC mice, a spontaneous model of Crohn's disease-like ileitis. The present study builds on these prior observations to identify a nonredundant, immunoprotective role for ERβ-specific signaling in TGF-β-depende
