The effects of Ring1A on gene expression profiles of lamina propria immune cells in DSS colitis at single cell level

Project description:immune cells in intestinal lamina propria play important roles in pathogenesis of DSS colitis. Here, we used single cell RNA sequencing (scRNA-seq) to reveale the intestinal immune landscape of DSS colitis and study the effects of Ring1A on intestinal immune cells.

Expression data of lamina propria macrophages from LysMCre and LysMCre;Arntfl/fl mice with DSS-induced acute colitis

Project description:Mice with myeloid ARNT deficiency (LysMCre;Arntfl/fl mice) exhibit defective resolution of DSS-induced acute colitis compared to LysMCre mice. This microarray is carried out to compare the phenotype of lamina propria macrophages from the two cohorts, and to identify factors that are disrupted by myeloid ARNT deficiency and can potentially contribute to the defective resolution of acute colitis.

Expression profiles of CD45+ cells in colon lamina propria from macrophage-specific E4BP4 transgenic mouse

Project description:Purpose: The goals of this study are to confirm the hypothesis that E4BP4 regulates colon specific anti-inflammatory macrophage. Methods: We generated transgenic mice (TG) with macrophage-specific E4BP4 overexpression. CD45+ cells in colon lamina propria were isolated at Zeitgeber Time (ZT) 0 from TG mice and WT littermates during the recovery period of dextran sulfate sodium (DSS)-induced colitis, and total RNA was extracted. CD45+ cells in colon lamina propria RNA profiles were generated by deep sequencing for two groups with one mouse sample each. Results: There were significant differences between TG and WT mice. Conclusions: E4BP4 increased the number of M2 macrophage population and upregulated anti-inflammatory genes.

miRNAs expressed in murine CD4+ T cells of splenocyte and lamina propria lymphocytes

Project description:The levels of some murine mRNAs and proteins are expressed discrepantly between the central immune system and the gut immune system in murine colitis. It was possible that RNA interference would result in some of the discrepancy. Thus, we compared microRNAs that are expressed in CD4+ T cells of spleen (SP) and lamina propria (LP) using Il-10+/- mice (C57BL/6 background) in order to reveal the role of miRNAs in murine colitis. Using 10-week-old female Il-10+/- mice, we investigated the difference in miRNA expressions between CD4+ T cells of spleen and that of lamina propria.

Global genome expression analysis of lamina propria derived WT and Nlrp6-/- Ly6C-hi inflammatory monocytes

Project description:Nlrp6-/- lamina propria Ly6C-hi monocytes in response to AOM/DSS have deficient TNFÎ± production, but increased production of other pro-inflammatory cytokines as compared to WT NLRP6 is a member of the Nod-like receptor family, whose members are involved in the recognition of microbes and/or tissue injury. NLRP6 was previously demonstrated to regulate the production of IL-18 and is important for protecting mice against chemically-induced intestinal injury and colitis-associated colon cancer. However, the cellular mechanisms by which NLRP6 reduces susceptibility to colonic inflammation remain unclear. Here, we determined that NLRP6 expression is specifically upregulated in Ly6Chi inflammatory monocytes that infiltrate into the colon during dextran sulfate sodium (DSS)-induced inflammation. Adoptive transfer of WT Ly6Chi inflammatory monocytes into Nlrp6-/- mice was sufficient to protect them from mortality, significantly reducing intestinal permeability and damage. NLRP6-deficient inflammatory monocytes were specifically defective in TNFÎ± production, which was important for reducing DSS-induced mortality and dependent on autocrine IL-18 signaling by inflammatory monocytes. Our data reveal a previously unappreciated role for NLRP6 in inflammatory monocytes, which are recruited during intestinal injury to promote barrier function and limit bacteria-driven inflammation. This study also highlights the importance of early cytokine responses, particularly NLRP6-dependent and IL-18-dependent TNFÎ± production in preventing chronic dysregulated inflammation. Ly6Chi monocytes were sorted from lamina propria of WT or Nlrp6-/- mice at day 10 of AOM/2%DSS. RNA was extracted and hybridized to the mouse 2.1 ST array.

Interleukin 17 B is protective in colitis by regulating colonic mononuclear phagocytes in mice

Project description:IL17B protected mice from dextran sodium sulfate (DSS)-induced colitis since IL17B deficiency resulted in severe DSS-induced colitis with exaggerated weight loss, shorter colon length, and elevated proinflammatory cytokine production in colon. For mechanism study, we use single cell transcriptional analyses of CD45+ immune cells in colonic lamina propria to detect the effect of IL-17B on colon LP immune cells in colitis. We found increased inflammatory macrophages infiltration in colon lamina propria after colitis induction expressing inflammatory cytokines such as S100a9, S100a8, Tnf, which was confirmed by real-time PCR and flow cytometry. Reconstitute of Il17b-/- mice with recombinant IL17B alleviated the severity of DSS-induced colitis. IL17B treatment also inhibited LPS-induced inflammation in bone marrow derived macrophage and in mice. These data indicate that IL17B exerting its inhibitory role in inflammation by regulating inflammatory macrophage response. In view of the protective effect of IL17B on DSS-induced colitis and LPS-induced inflammation, IL17B might represent a novel potential therapeutic approach to treat the inflammation.

Comparison of splenic and small intestine lamina propria dendritic cells

Project description:This SuperSeries is composed of the following subset Series: GSE22127: Expression profiling of small intestine lamina propria dendritic cells GSE22128: Expression profiling of splenic dendritic cells Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) and compared it to splenic DCs (CD11c+ DC), from mice. We sought to determine the unique genetic profile of small intestine lamina propria CD11c+ cells compared to splenic CD11c+ cells. We performed a meta-analysis using the expression profiles of Intestinal lamina propria CD11c+ CD11b+ DCs (GSM550122), Intestinal lamina propria CD11c+ CD11b- DCs (GSM550121) and Splenic CD11c+ DCs (GSM550126). This study combined and re-normalized the microarray data from GSE22127 and GSE22128 studies. Refer to individual Series for additional details
