Abstract: A plethora of functional and genetic studies have suggested a key role for the IL-23 pathway in chronic intestinal inflammation. Currently, pathogenic actions of IL-23 have been ascribed to specific effects on immune cells. Herein, we unveil a protective role of IL-23R signaling. Mice deficient in IL-23R expression in intestinal epithelial cells ($\textit{Il23R}^{{\Delta}IEC}$) have reduced Reg3b expression, show a disturbed colonic microflora with an expansion of flagellated bacteria, and succumb to DSS colitis. Surprisingly, $\textit{Il23R}^{{\Delta}IEC}$ mice show impaired mucosal IL-22 induction in response to IL-23. aThy-1 treatment significantly deteriorates colitis in $\textit{Il23R}^{{\Delta}IEC}$ animals, which can be rescued by IL-22 application. Importantly, exogenous Reg3b administration rescues DSS-treated $\textit{Il23R}^{{\Delta}IEC}$ mice by recruiting neutrophils as IL-22-producing cells, thereby restoring mucosal IL-22 levels. The study identifies a critical barrier-protective immune pathway that originates from, and is orchestrated by, IL-23R signaling in intestinal epithelial cells.
