The molecular mechanisms underlying neuronal leptin and insulin resistance in obesity and diabetes remain unclear. Here we show that induction of the unfolded protein response transcription factor spliced X-box binding protein 1 (Xbp1s) in pro-opiomelanocortin (Pomc) neurons alone is sufficient to protect against diet-induced obesity as well as improve leptin and insulin sensitivity, even in the presence of strong activators of ER stress. We also demonstrate that constitutive expression ofXbp1sinPomcneurons contributes to improved hepatic insulin sensitivity and suppression of endogenous glucose production. Notably, elevatedXbp1slevels inPomcneurons also resulted in activation of theXbp1saxis in the liver via a cell-nonautonomous mechanism. Together our results identify critical molecular mechanisms linking ER stress in arcuatePomcneurons to acute leptin and insulin resistance as well as liver metabolism in diet-induced obesity and diabetes.
