IL-23R transduces signals into the intestinal epithelium
Il23RΔIEC mice are susceptible to DSS colitis and have a disturbed gut microflora
Epithelial IL-23R is required for optimal secretion of the c-type lectin Reg3b
The c-type lectin Reg3b promotes recruitment of IL-22-producing cells as an alarmin
Systemic substitution of Reg3b rescues the gut barrier defect of Il23RΔIEC mice
