Project description:We plan to describe different characters of LTi-like cells from distinct tissues. Also, we further compare the LTi-like cells from both Id2fl/fl and RorccreId2fl/fl mLN and gut.
Project description:To search for factors that affect naive CD4+ T (TN) cell phenotypes in spleen, we performed RNA-seq analysis to compare mRNA expression between freshly-prepared spleen and mLN hematopoietic cells.
Project description:To analyze difference between spleen and mLN TN cells, RNA-seq analysis was performed on TN cells freshly prepared from each organ.
Project description:Gut microbiota plays a significant role in shaping gut and systematic immune and huge strain- and species- dependent differences exit. Using in-vitro MLN co-culture models, we want to initially uncover these differences. MLN cells were isolated from C57BL/6 mice and co-cultured with bacterial cells with or without anti-CD3 and anti-CD28 antibodies for three days. After that, IL-10 in cell supernatant was measured and RNA was extracted using Trizol reagent. RNA-seq was performed on Illumina Hiseq X ten. Raw sequenced data were filtered by fastp and clean data were mapped to reference genome (Mus_musculus, GRCm39). Data processing adopted featurecounts in subread, abundance_estimates_to_matirx.pl in Trinity, DEseq and ClusterProfiler. We found that all bacterial species activated the innate immunity response. However, only Akkermansia muciniphila and Clostridium butyricum had cognate T cell antigen and activated adaptive immunity responses even without stimulus.
Project description:Transcriptome analysis of dentritic cells from the spleen (CD11c+) or MLN (CD11c+CD103+) of mice with DC-specific deletion of TGFBR2 gene, or their control littermates. TRGFR2 gene was deleted in dendritic cells using Cre/lox approach. Mice with this deletion develop spontaneous multi-organ autoimmune inflammation and die by 15 weeks of age. Splenic CD11c+ Dc were isolated by magetic cell sorting. MLN CD11c+CD103+ DC were flow sorted. RNA was isolated using RNAqueous-Micro kit (Ambion) and analyzed using Affymetrix Mouse Exon 1.0 ST Array

Project description:We purified two populations of human duodenal MLN-expressing enteroendocrine cells (Venus+ and Venus-) from mature differentiated hMLN-Venus organoids by FACS and identified transcripts enriched in endocrine cell lineages.
Project description:To find the signalling pathway involved in WT/2D2 CD4+ gut T cell (CD4+ intraepithelial lymphocytes, CD4+IEL) differentiation, particulary to determine whether aryl hydrocarbon receptor (AHR) pathway is involved. Gene expression was analyzed ex vivo in CD4+ T cells that were sorted from Wild type-Gut / 2D2 mouse-Gut / Wild type-Spleen / 2D2 mouse-Spleen (N=3 per group). The genes highly expressed in WT/2D2 Gut compared to WT/2D2 Spleen were selected by k-means clustering. AHR pathway related genes (IPA software) were further selected.
