Enteric Nervous System Derived IL-18 Orchestrates Mucosal Barrier Immunity [DropSeq]

ABSTRACT: Using DropSeq single cell RNA sequencing, we report that neuronal derived-IL-18 is required for goblet cell expression of intestinal antimicrobial protein expression Mucosal barrier immunity is essential for the maintenance of the commensal microflora and combating invasive bacterial infection. Although immune and epithelial cells are thought to be the canonical orchestrators of this complex equilibrium, here we show that the enteric nervous system (ENS) plays an essential and non-redundant role in governing the anti-microbial protein (AMP) response. Using confocal microscopy and single-molecule fluorescence in situ mRNA-hybridization (smFISH) studies, we observed that intestinal neurons produce the pleiotropic cytokine IL-18. Strikingly, deletion of IL-18 from the enteric neurons alone, but not immune or epithelial cells, rendered mice susceptible to invasive Salmonella typhimurium (S.t.) infection. Mechanistically, unbiased RNA sequencing and single cell sequencing revealed that enteric neuronal IL-18 is specifically required for homeostatic goblet cell AMP production. Together, we show that neuron derived IL-18 signaling controls tissue wide intestinal immunity and has profound consequences on the mucosal barrier and invasive bacterial killing.

Rhesus macaque ileal loop study

Project description:Salmonella enterica serotype Typhimurium cause a localized enteric infection in immunocompetent patients while human immunodeficiency virus (HIV)-infected patients develop a life threatening bacteremia. We used a rhesus macaque ileal loop model to study how simian immunodeficiency virus (SIV) infection triggers defects in mucosal barrier function that enhance S. Typhimurium dissemination. SIV infection resulted in significant depletion of CD4+ T cells in the intestinal mucosa. Gene expression profiling revealed a defective TH17 response (with suppression of IL-17 and IL-22 expression) and impaired homeostasis of the intestinal epithelium in SIV-infected animals during NTS infection. These findings correlated with an impaired ability of lamina propria CD4+ T cells from SIV-infected macaques to produce IL-17 upon ex vivo stimulation, while production of IFNï§ was not affected. This cytokine imbalance in SIV-infected animals was associated with reduced expression of genes required for intestinal epithelial maintenance and repair, increased fluid secretion during NTS infection, epithelial damage and translocation of a non-invasive S. Typhimurium mutant. Although no defects in neutrophil recruitment were noted, the ileum of SIV-infected animals contained lower levels of the enzyme myeloperoxidase, which may indicate defects in neutrophil killing capacity. S. Typhimurium was recovered in markedly increased numbers from the mesenteric lymph nodes of SIV-infected macaques, illustrating the increased potential for systemic dissemination during co-infection. Our data suggest that SIV-infection causes a multi-factorial defect in mucosal barrier function that promotes bacterial dissemination.

Transcription profiling of mouse rectum after physiological stress

Project description:Using isolation stress model, we showed that goblet cell-dependent mucosal barrier functions in the mouse rectum was more vulnerable to stress than the colon. We also found that isolation stress specifically stimulated IL-18 production only in the rectum. Furthermore, the crucial role of IL-18 in the stress response of the mouse rectum was confirmed using IL-18 knockout mice. Microarray analysis was used to assess the stress response and to identify responsible genes for the vulnerability of the mouse rectum to isolation stress. Experiment Overall Design: Total RNA was prepared from the colon and the rectum of wild-type and IL-18 knockout mice before isolation and 8 days after starting isolation. The one GSM sample of microarray analysis was made by pooling an equal amount of total RNA 5 mice of each group. Agilent whole mouse genome oligonucleotide microarray was used to measure gene expression in these samples according to the manufactureâ??s protocol.

Faecalibacterium prausnitzii promotes intestinal epithelial IL-18 production through activation of the HIF1A pathway

Project description:In this study, we investigated the regulation of interleukin-18 (IL-18) expression, crucial for intestinal barrier integrity, in inflammatory bowel disease (IBD). Through experiments with Caco-2 cells, we demonstrated that HIF1α-mediated IL18 expression induced by F. prausnitzii was dependent on HIF1α, suggesting a potential role for butyrate-producing gut bacteria in promoting mucosal healing in IBD.
