RNA-seq of mouse ileum to investigate the role of IL-17 receptor signaling in Paneth cells in their biology and intestinal physiology

ABSTRACT: IL-17 receptor plays a major role in the antibacterial defense and regulation of host-microbiota interaction. However its impact on Paneth cells, cell-type specific for production of antibacterial peptides, is still not clear. Here, we used genetic depletion of IL-17 receptor specific for Paneth cell population (Defa6-iCre x Il17ra-flox) and performed the RNA sequencing on FACS-sorted Paneth cells and also complete ileum tissue, comparing Cre+ and Cre- littermates.

Interleukin (IL)-17 protects epithelial barriers by inducing the secretion of antimicrobial peptides. However, the effect of IL-17 on Paneth cells (PCs), the major producers of antimicrobial peptides in the small intestine, is unclear. Here, we show that the targeted ablation of the IL-17 receptor (IL-17R) in PCs disrupts their antimicrobial functions and decreases the frequency of ileal PCs. These changes become more pronounced after colonization with IL-17 inducing segmented filamentous bacter ...[more]

RNA-seq of crypt cells from mouse small intestinal epithelium with an intestinal-epithelial specific deletion of LSD1 compared to wild type crypts

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (KO) (Villin-Cre+; Lsd1f/f) mice. We dissociated crypts into single cells, and FACS sorted Epcam+ cells, to avoid immune-cell contamination. RNA was directly isolated from these sorted cells, and this was used for RNA seq. As KO crypts are different from WT crypts (KO crypts lack Paneth cells), identifying genes specifically regulated by LSD1 helps us to identify how LSD1 regulates intestinal crypt biology. Specifically, because we were able to combine this with ChIP-seq of the same cells, to identify where H3K4me1 levels (target of the histone demethylase LSD1) were different in the genome.

ATAC-sequencing mice small intestinal epithelium with intestinal epithelium specific LSD1 knock out compared to wild type

Project description:To study the epigenetic regulation of intestinal epithelium we focus on the role of chromatin modulators. Lysine-specific histone demethylase 1a (KDM1A, LSD1) is one of the enzymes that can erase the H3K4me1/2 mark. To assess the role of LSD1 in intestinal epithelium we studied wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (KO) (Villin-Cre+; Lsd1f/f) mice. We found that KO mice completely lack Paneth cells, and have altered stem cell characteristics compared to WT littermates. To assess genome-wide ATAC levels in WT and KO small intestines, we isolated intestinal epithelium tissue from wild type mice and LSD1 KO mice. This tissue was digested to single cells and performed ATAC seq as described in the protocols.

Paneth cells constitute the niche for Lgr5 stem cells in intestinal crypts

Project description:Homeostasis of self-renewing small intestinal crypts results from neutral competition between Lgr5 stem cells, small cycling cells located at crypt bottoms1, 2. Lgr5 stem cells are interspersed between terminally differentiated Paneth cells, that are known to produce bactericidal products such as lysozyme and cryptdins/defensins3. Single Lgr5-expressing stem cells can be cultured to form long-lived, self-organizing crypt-villus organoids in the absence of non-epithelial niche cells4. Here, we note a close physical association of Lgr5 stem cells with Paneth cells in vivo and in vitro. CD24+ Paneth cells express EGF, TGF?, Wnt3 and the Notch-ligand Dll4, all essential signals for stem cell maintenance in culture. Co-culturing of sorted stem cells with Paneth cells dramatically improves organoid formation. This Paneth cell requirement can be substituted by a pulse of exogenous Wnt. Genetic removal of Paneth cells in vivo results in the concomitant loss of Lgr5 stem cells. In colon crypts, CD24+ cells residing between Lgr5 stem cells may represent the Paneth cell equivalents. We conclude that Lgr5 stem cells compete for essential niche signals provided by a specialized daughter cell, the Paneth cell. We used intestinal cell fractions from Lgr5-EGFP-ires-CreERT2 mice, expressing GFP under the control of the Lgr5 promoter. RNA was isolated from two FACS sorted cell populations: stem cells were sorted based on high level of GFP expression (GFPhi) and Paneth cells were sorted based on high level of CD24 expression (CD24hi) and high side-scatter (SSChi). Differentially labelled cRNA from GFPhi and CD24hi/SSChi cells from two different sorts (each combining ten individual mice) were hybridized on 4X44K Agilent Whole Mouse Genome dual colour Microarrays (G4122F) in two dye swap experiments, resulting in four individual arrays.

RNA-seq of crypt and villus cells from mouse small intestinal epithelium with an intestinal-epithelial specific deletion of LSD1 compared to wild type controls

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts and villus from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (cKO) (Villin-Cre+; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% deletion efficiency. RNA was directly isolated from intestinal crypt and villus, and this was used for RNAseq. Gene expression analysis of cKO derived crypt and villus provides a spatially restricted outlook on the maturation status of the intestinal epithelium in the villi and the absence of Paneth cells in the crypt.

RNA-seq of mouse small intestinal organoids with an intestinal-epithelial specific deletion of LSD1 compared to wild type

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we grew small intestinal organoids in vitro from mice with an epithelial specific deletion of LSD1 (Villin-Cre+; Lsd1f/f) and from wild type (Villin-Cre-; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% recombination efficiency. Similar to intestinal epithelium from mice with an intestinal epithelium specific LSD1-KO, Paneth cells are not present in LSD1-KO small intestinal organoids. We used these sequencing data to show intrinsic epithelial changes in the intestinal epithelium caused by LSD1 deletion in the absence of microbiota and surrounding in vivo cell types.
