- Abstract
- Visceral adipose tissue (VAT) is an energy store and endocrine organ critical for metabolic homeostasis. Regulatory T (T(reg)) cells restrain inflammation to preserve VAT homeostasis and glucose tolerance. Here, we show that the VAT harbors two distinct T(reg) cell populations: prototypical serum stimulation 2-positive (ST2(+)) T(reg) cells that are enriched in males and a previously uncharacterized population of C-X-C motif chemokine receptor 3-positive (CXCR3(+)) T(reg) cells that are enriched in females. We show that the transcription factors GATA-binding protein 3 and peroxisome proliferator-activated receptor-γ, together with the cytokine interleukin-33, promote the differentiation of ST2(+) VAT T(reg) cells but repress CXCR3(+) T(reg) cells. Conversely, the differentiation of CXCR3(+) T(reg) cells is mediated by the cytokine interferon-γ and the transcription factor T-bet, which also antagonize ST2(+) T(reg) cells. Finally, we demonstrate that ST2(+) T(reg) cells preserve glucose homeostasis, whereas CXCR3(+) T(reg) cells restrain inflammation in lean VAT and prevent glucose intolerance under high-fat diet conditions. Overall, this study defines two molecularly and developmentally distinct VAT T(reg) cell types with unique context- and sex-specific functions.
