A schematic model for the dynamical regulation of colonic macrophage–mediated immune responses against enteric bacterial infections by RBP-J. RBP-J is a crucial regulator in colonic macrophage–mediated immune responses against the enteric pathogen C. rodentium. In the immune response phase (phase A), RBP-J KO mice exhibit compromised clearance of pathogens due to diminished IL-6–induced Th17 immune responses secondary to up-regulation of the miRNA-17∼92 cluster and subsequent suppression of C/EBPβ protein expression. In the late phase (phase B), RBP-J KO mice eventually clear C. rodentium owing to late persistence of pathogen-dependent ILC3-derived IL-22 activated by CD64+Ly6C+ colonic macrophages.
