Enteric nervous system: timecourse analysis of longitudinal muscle and myenteric plexus (LMMP) in mice

Project description:Samples of dissociated mouse small intestinal longitudinal muscle-myenteric plexus were prepared from post natal day 10 (P10), P20, and P60, each with two biological replicates. Samples were run through the 10x Chromium 3' Single Cell Gene Expression platform v3.1

Single-cell transcriptomic and epigenetic profiling of mouse myenteric plexus glial cells

Project description:This study was undertaken to define the molecular subtypes of myenteric plexus glial cells in mice, and to understand the molecular basis for glial cells’ capacity to become neurons. Methods: We performed single-cell RNA sequencing and single-nucleus ATAC sequencing of enteric neurons from small intestine at the adolescent mice (on or near postnatal day of life 14). We also performed both single-cell RNA sequencing and single-nucleus ATAC sequencing on 3-dimensional neurosphere cultures. Results: We identify numerous distinct transcriptional subgroups of myenteric plexus glial cells, including cells expressing genes associated with neuronal differentiation. Epigenetic analysis shows distinct chromatin accessibility profiles that correlate with gene expression patterns. Glial cells maintain open chromatin at gene loci associated with neuronal fate. 3-dimensional cultures provide a niche for active neurogenesis. Chromatin closes at glial-associate loci during neurogenesis. Conclusion: Utilizing single-cell RNA sequencing and single-nucleus ATAC sequencing, we identify myenteric glial cell subtypes and uncover a molecular basis for a glial-to-neuronal fate transition.

Transcription profiling of mouse small intestine interstitial cells of Cajal (ICC) from deep muscular plexus and myenteric plexus

Project description:Interstitial cells of Cajal (ICC) have important functions in regulation of motor activity in the gastrointestinal tract. In murine small intestine ICC are gathered in the region of the myenteric plexus (ICC-MY) and within the deep-muscular plexus near the submucosal surface of the circular muscle layer (ICC-DMP). These two classes of ICC have different physiological functions. ICC-MY are pacemaker cells and generate the slow wave electrical rhythmicity of gastrointestinal organs. ICC-DMP form synaptic connections with the varicose nerve terminals of enteric motor neurons and are involved in reception and transduction of motor neurotransmission. In the present study we used recently developed highly selective techniques to isolate the two classes of ICC from enzymatically dispersed intestinal muscles by fluorescence-activated cell sorting. Transcriptional expression of the two functional classes was investigated using DNA microarray analysis. Experiment Overall Design: ICC-DMP and ICC-MY cells were isolated from the murine small intestinal tissues and their transcriptional expression was compared with that of the tunica muscularis tissues. Transcriptional expression profiles of ICC-DMP and ICC-MY were compared to each other also.

Identification of novel genes involved in postnatal longitudinal muscle growth

Project description:Overall goal: To identify genes involved in postnatal longitudinal muscle growth through misregulation by neonatal brachial plexus injury leading to contracture formation. Purpose of analysis: To generate a transcriptional profile of mice given unilateral neonatal brachial plexus injuries. Experimental structure: The transcriptional profiles generated from the RNA-Seq analysis would be compared as neonatally-denervated biceps muscle versus the contralateral control to identify genes regulating postnatal longitudinal muscle growth.

A Population of Radio-Resistant Macrophages in the Deep Myenteric Plexus Contributes to Postoperative Ileus Via Toll-Like Receptor 3 Signaling

Project description:Postoperative ileus (POI) is triggered by an innate immune response in the muscularis externa (ME) and is accompanied by bacterial translocation. Bacteria can trigger an innate immune response via toll-like receptor (TLR) activation, but the latter’s contribution to POI has been disproved for several TLRs, including TLR2 and TLR4. Herein we investigated the role of double-stranded RNA detection via TLR3 and TIR-domain-containing adapter inducing interferon-b (TRIF) signaling pathway in POI. POI was induced by small bowel intestinal manipulation in wt, TRIF-/-, TLR3-/-, type I interferon receptor-/- and interferon-b reporter mice, all on C57BL/6 background, and POI severity was quantified by gene expression analysis, gastrointestinal transit, and leukocyte extravasation into the ME. TRIF/ TLR3 deficiency reduced postoperative ME inflammation and prevented POI. With bone marrow transplantation, RNA-sequencing, flow cytometry, and immunohistochemistry we revealed a distinct TLR3-expressing radio-resistant MHCIIhiCX3CR1- IBA-1+ resident macrophage population within the deep myenteric plexus. TLR3 deficiency in these cells, but not in MHCIIhiCX3CR1+ macrophages, reduced cytokine expression in POI. While this might not be an exclusive macrophage-privileged pathway, the TLR3/TRIF axis contributes to proinflammatory cytokine production in MHCIIhiCX3CR1- IBA-1+ macrophages during POI. Deficiency in TLR3/TRIF protects mice from POI. These data suggest that TLR3 antagonism may prevent POI in humans.

Intestinal crypt-derived enteroid coculture in presence of peristaltic longitudinal muscle myenteric plexus.

Project description:The role of enteric neurons in driving intestinal peristalsis has been known for over a century. However, in recent decades, scientists have begun to unravel additional complex interactions between this nerve plexus and other cell populations in the intestine. Investigations into these potential interactions are complicated by a paucity of tractable models of these cellular relationships. Here, we describe a novel technique for ex vivo coculture of enteroids, so called "mini-guts," in juxtaposition to the longitudinal muscle myenteric plexus (LMMP). Key to this system, we developed a LMMP culture media that: (i) allows the LMMP to maintain ex vivo peristalsis for 2 weeks along with proliferation of neurons, glia, smooth muscle and fibroblast cells, and (ii) supports the proliferation and differentiation of the intestinal stem cells into enteroids complete with epithelial enterocytes, Paneth cells, goblet cells, and enteroendocrine cells. Importantly, this technique identifies a culture condition that supports both the metabolic needs of intestinal epithelium as well as neuronal elements, demonstrating the feasibility of maintaining these two populations in a single culture system. This sets the stage for experiments to better define the regulatory interactions of these two important intestinal cell populations.
