Innate immune homeostasis by the homeobox gene caudal and commensal-gut mutualism in Drosophila.

Although commensalism with gut microbiota exists in all metazoans, the host factors that maintain this homeostatic relationship remain largely unknown. We show that the intestinal homeobox gene Caudal regulates the commensal-gut mutualism by repressing nuclear factor kappa B-dependent antimicrobial ... View More
