The cellular composition of visceral adipose tissue (VAT) and release of cytokines by such cells within VAT has been implicated in regulating obesity and metabolic homeostasis. We show the importance of IL-25-responsive innate cells, that release the Th2 cytokine IL-13, in regulating weight and glucose homeostasis in mouse models of diet-induced obesity. Treating obese mice with IL-25 induces weight loss and improves glucose tolerance, and is associated with increased infiltration of ILC2s, type I and type II natural killer T (NKT) cells, eosinophils and alternatively activated macrophages (AAM) into the VAT. By depleting ILC2 in obese Rag1−/− mice we observe exacerbated weight gain and glucose intolerance. Conversely, transferring ILC2 or type I or type II NKT cells into obese mice induces transient weight loss and stabilizes glucose homeostasis. Our data identifies a mechanism whereby IL-25 eliciting IL-13 producing innate cells regulates inflammation in adipose tissue and prevents diet-induced obesity.
