Project description:Microbial density and diversity increase in distal intestinal segments, affecting tissue physiology, metabolism, and function of both the immune and nervous systems. We characterized the influence of the microbiota on murine intrinsic enteric-associated neurons (iEAN). We found that iEAN are functionally adapted to the intestinal segment they occupy, with a stronger microbiota influence on ileal and colonic neurons. Chemogenetic characterization of microbiota-influenced iEAN identified a subset of viscerofugal CART+ neurons, enriched in the ileum and colon, able to modulate feeding and glucose metabolism. Retro- and anterograde tracing revealed that CART+ viscerofugal neurons send axons to the prevertebral ganglia and are poly-synaptically connected to the liver and pancreas. Microbiota depletion led to NLRP6 and Caspase 11-dependent loss of CART+ neurons, and impaired liver-mediated gluconeogenesis. Our results demonstrate a region-specific adaptation of enteric neurons and indicate that iEAN subsets are capable of regulating blood glucose levels independently from the central nervous system.

Project description:The gut microbiota, immune system, and enteric nervous system interact to regulate adult gut physiology. Yet the mechanisms establishing gut physiology during development remain unknown. We report that in developing zebrafish, enteroendocrine cells produced IL-22 in response to microbial signals before lymphocytes populate the gut. In larvae, IL-22 shaped the gut microbiota, increased Lactobacillaceae abundance and ghrelin expression to promote gut motility. Impaired motility and ghrelin expression were restored in il22-/- zebrafish by transfer of microbiota from wild-type zebrafish or by monoassociation with Lactobacillus plantarum. IL-22-deficient mice had impaired gut motility and reduced ghrelin expression in early life too, indicating a conserved function. Thus, before immune system maturation, enteroendocrine cells regulate early-life gut function by controlling the microbiota via IL-22.

Project description:The enteric nervous system (ENS) senses microbiota-derived signals and orchestrates mucosal immunity and epithelial barrier functions, in health and disease. However, mechanistic dissections of intestinal neuro-immune-microbiota communications remain challenging and existing research methods limit experimental controllability and throughput. Here, we present a novel optogenetics-integrated gut organ culture system that enables real-time, whole-tissue stimulation of specific ENS lineages, allowing for detailed analysis of their functional impact. We demonstrate that optogenetic activation of enteric cholinergic neurons rapidly modulates intestinal physiology. Interestingly, distinct neuronal firing patterns differentially modulate neuro-immunological gene expression and epithelial barrier integrity. Furthermore, diverse enteric neuronal lineages exert distinct regulatory roles. While cholinergic activation promotes gene-sets associated with type-2 immunity, tachykininergic enteric neurons differentially control mucosal defense programs. Remarkably, luminal introduction of the immunomodulatory bacterium T. ramosa significantly remodeled cholinergic-induced neuro-immunological transcription. These findings suggest that complex combinatorial signals delivered by gut microbes and enteric neurons are locally integrated to fine-tune intestinal immunity and barrier defense. Collectively, we provide a powerful platform for systematic discovery and mechanistic exploration of functional neuroimmune connections, and their potential modulation by microbes, drugs or metabolites.

Project description:The enteric nervous system (ENS) can control most essential gut functions owing to its organization into complete neural circuits consisting of a multitude of different neuronal subtypes. We used microarrays to identify transcription factor networks and signaling pathways involved in diversification and differentiation of enteric neurons during development of the enteric nervous system.
