The interleukin 12 (IL12)/IL23 common pathway has been found to play a determinant role in the induction of inflammation in adaptive immune responses In particular, IL23 promotes the differentiation of naïve T helper cells into Th17 phenotype with the concomitant secretion of several inflammatory cytokines such as IL17 and IL22, whereas IL12 induces the Th1 polarization and Commensal microbiota are known to be required for the elicitation of host Th17 responses, which may mediate autoimmune diseases Here, we demonstrate that the IL23 pathway dynamically regulates the abundance of certain commensals and maintains barrier function Barrier disruption results in systemic dissemination of microbial products, which invokes the IL23 pathwayResults ILC3s stimulated with IL23 plus IL1β upregulated the vitamin D receptor and responded to 1,25D with downregulation of the IL23 receptor pathway Consequently, 1,25D suppressed IL22, IL17F, and GMCSF production from tonsillar and gut ILC3s In parallel, 1,25D upregulated genes linked to the IL1β signaling pathway, as well as the IL1βinducible cytokines IL6, IL8,
