Enterocytes, fibroblasts and myeloid cells synergize in anti-bacterial and anti-viral pathways with IL22 as the central cytokine

Abstract

ten Klooster et al. use ileum-derived organoids and report that bacterial and viral stimuli can drive IL22 production by T cells via distinct signaling pathways, and that IL22 can stimulate expression of anti-microbial and antiviral factors. This study sheds light on how enterocytes, fibroblasts and myeloid cells work synergistically to induce IL22 response against both bacteria and viruses.
