Analysis of C57BL/6 colon cultures treated with 10 ng/ml of interleukin-22 (IL-22) for 24 hours. IL-22, a member of the IL-10 family of cytokines, can induce a marked antimicrobial response in vitro. Results provide insight into the molecular basis of IL-22 induced host defense mechanisms.

(Submitter supplied) Infection by attaching and effacing (A/E) pathogens poses a serious threat to public health, as was highlighted by the recent outbreak of E. coli O157:H7 infection in the United States. Here, by using a murine A/E pathogen, Citrobacter rodentium, we demonstrate that C. rodentium infection is lethal to IL-22-/- mice within two weeks. IL-22, in the early phase of infection, is indispensable for preventing the invasion of bacteria through the intestinal epithelium, and thereby preventing systemic spread and mortality. more...

(Submitter supplied) IL-22 acts on epithelial cells and has been shown to induce tissue protective and wound healing responses in these cells. But it has recently been decribed that IL-22 exacerbates ileatis after infection with T. gondii. The goal of the study is to identify the IL-22-dependent genes during T. gondii infection in order to understand why IL-22 is pathogenic in this context.

(Submitter supplied) Profiling of a total of 34,790 genes revealed a wide range of expression changes during the course of C. rodentium infection in murine colon. The majority of changes were observed during weeks 1 and 2, while relatively fewer changes were seen at week 3. Interestingly, chemokines made up 20% of the top twenty upregulated genes.

(Submitter supplied) RBP-J is a master transcriptional factor of Notch signaling, which plays important roles in developmental processes as well as regulating macrophage-mediated inflammatory responses. However, the regulation of RBP-J on miRNAs are less studied. So we sequenced microRNAs from BMDMs derived from the LyZ2 Cre control (WT) and RBP-J conditional knockout mice (RBP-J KO; Rbpjf/f LyZ2 Cre) to address the roles of RBP-J on regulating miRNAs in macrophages.

(Submitter supplied) Background: Yersinia outer protein (Yop) H is a secreted virulence factor of Yersinia enterocolitica which inhibits phagocytosis of Y. enterocolitica and promotes virulence of Y. enterocolitica (Ye) in mice. The aim of this study was to address whether and how YopH affects the innate immune response against Ye in mice. Results: For this purpose mice were infected with wild type Ye (pYV+) or a YopH-deficient Ye mutant strain (DyopH). more...

(Submitter supplied) Group 3 innate lymphoid cells (ILC3) are innate immune effectors that contribute to host defense. Whether ILC3 functions are stably modified following pathogen encounter is unknown. Here we assess the impact of a time-restricted enterobacterial challenge to long-term ILC3 activation. We found that intestinal ILC3 persist for months in an activated state following exposure to Citrobacter rodentium. Upon rechallenge, these “trained” ILC3 proliferate, display enhanced interleukin (IL)-22 responses, and have a superior cell-intrinsic capacity to control infection compared to naïve ILC3. more...

(Submitter supplied) Innate lymphoid cells (ILCs) are important for mucosal immunity. The intestine harbors all ILC subsets; however, how these cells orchestrate each other to achieve immune homeostasis and mount appropriate immunity during infection remains elusive. Here, we show that the adaptation of the aryl hydrocarbon receptor (Ahr) expression in the gut is a key regulatory mode for the host to keep the ILC balance. more...

(Submitter supplied) We report that adhesion of microbes to intestinal epithelial cells is a critical cue for Th17 induction. SFB colonized in the intestine of mice can adhere to mouse small intestinal epithelial cells and induce intestinal Th17 cells. However, SFB colonized in rats cannot adhere to mouse intestinal epithelial cells and induce Th17 cells. Likewise, Citrobacter rodentium (WT) can adhere to mouse colonic epithelial cells and induce Th17 cells, but non-adherent mutant of C. more...

(Submitter supplied) Mice with and without IFNAR expression were treated with broad-spectrum antibiotics for more than 10 days, either infected with MNV or left uninfected and then treated with 3% DSS in drinking water for 6 days. Intestinal epithelial cells were isolated from the colon and sorted and RNA extracted for RNASeq analysis. We found that mice with IFNAR expression on IEC and infected with MNV had a gene expression signature of DNA repair similar that induced by IL-22 signaling.

(Submitter supplied) Innate lymphoid cells (ILCs) are tissue-resident lymphocytes subdivided into ILC1s, ILC2s and ILC3s based on core regulatory programs and signature cytokines secreted. ILCs exhibit functional plasticity: for instance, human IL-22-producing ILC3s convert into IFN-γ-producing ILC1-like in vitro. Whether this conversion occurs in vivo is unclear. Using flow cytometry, mass cytometry and scRNAseq, here we found that ILC3s and ILC1s occupy opposite ends of a spectrum including discrete subsets in human tonsils. more...

(Submitter supplied) Innate immune responses must be regulated in the intestine to prevent excessive inflammation. Here, using gene reporter mice, we show that a subset of mouse colonic macrophages constitutively produced the anti-inflammatory cytokine IL-10. In mice infected with Citrobacter rodentium, which is considered similar to enteropathogenic Escherichia coli infection in humans, macrophage IL-10 was required to prevent intestinal pathology and to promote survival. more...

(Submitter supplied) Retinoic-acid receptor-related orphan receptor-γt-positive (RORγt+) innate lymphoid cells (ILCs) produce interleukin (IL)-22 and IL-17, which are critical for protective immunity against enteric pathogens. The molecular mechanism underlying the development and survival of RORγt+ ILCs is not thoroughly understood. Here we show that Dedicator of cytokinesis 8 (DOCK8), a scaffolding protein involved in cytoskeletal rearrangement and cell migration, is essential for the protective immunity against Citrobacter rodentium. more...

(Submitter supplied) Homeostasis of the gut microbiota is pivotal to the survival of the host. Intestinal T cells and Innate Lymphoid cells (ILCs) control the composition of the microbiota and respond to its perturbations. Interleukin 22 (IL-22) plays a pivotal role in the immune control of gut commensal and pathogenic bacteria and is secreted by a heterogeneous population of intestinal T cells, NCR- ILC3 and NCR+ILC3. Expression of NCR by ILC3 is believed to define an irreversible effector ILC3 end-state fate in which these cells are key to control of bacterial infection via their production of IL-22. Here we identify the core transcriptional signature that drives the differentiation of NCR- ILC3 into NCR+ ILC3 and reveal that NCR+ILC3 exhibit more plasticity than originally thought, as NCR+ ILC3 can revert to NCR- ILC3. Contrary to the prevailing understanding of NCR+ ILC3 genesis and function, in vivo analyses of mice conditionally deleted of the key ILC3 genes Stat3, Il22, Tbet and Mcl1 demonstrated that NCR+ ILC3 were not essential for the control of colonic infections in the presence of T cells. However, NCR+ ILC3 were mandatory for homeostasis of the caecum. Our data identify that the interplay of intestinal T cells and ILC3 results in robust complementary fail-safe mechanisms that ensure gut homeostasis.
