Single cell RNA and TCR profiling of tetramer sorted mouse mLN and IELs.

ABSTRACT: We utilized H2-I-Ab tetramers to isolate CD4 T cells from mice to characterize the functional characteristics of ileal intraepithelial T cells and their lymphoid counterparts in the corresponding draining lymph nodes (mLN). Non-CD4 T cells (B220+, CD11b+, CD11c+, F4/80+, CD8a+) were excluded before FACS-sorting of CD45+CD3+CD4+ tetramer-specific T cells discriminated by double-positive staining with dual-labeled tetramer fluorophores. We recovered tetramer+ and tetramer- IELs and mLN T cells, and profiled them by single-cell RNA and TCR sequencing.

Total and cholera toxin B-tetramer specific T cells from Peyer's patches and mesenteric lymph nodes

Project description:T cells were separately isolated from MLN and PP from two naive mice, and T cells binding to a cholera toxin B subunit specific MHC II tetramer from mice orally immunized with cholera toxin 7 days or boosted 5 days with a second dose of cholera toxin. Cells were purified using flow cytometric cell sorting and 3´ (n=5) or 5´ (n=5) libraries were constructed using the 10X workflow. From 5´libraries TCR libraries were also constructed and sequenced.

RNA libraries of sorted CD8+ memory T cells from the spleen and RNA libraries of sorted IELs from the small intestine of C57BL/6J mice

Project description:Intraepithelilal lymphocytes (IELs) are located at the intestinal barrier where they can offer swift protection against invading pathogens. However, they are kept in a heightened state of activation resembling effector T cells, but without cytokine production or clonal proliferation. They also posses altered metabolic pathways than CD8+ memory T cells from spleen. With differentially expressed gene analysis of intestinal IELs and CD8+ memory T cells from spleen, we confirmed increased expression of metabolic enzymes involved in lipid uptake and lipid metabolism in IELs compared with CD8+ memory T cells. This was particularly the case for enzymes involved in mevalonate, lanosterol and cholesterol synthesis pathways, suggesting increased lipid metabolite generation. Differential gene expression showed also strong predisposition for cytotoxic potential that IELs possess in comparison to CD8+ memory T cell.

T cell receptor is required for differentiation but not maintenance of intestinal CD4+ intraepithelial lymphocytes

Project description:The gut epithelium is populated by intraepithelial lymphocytes (IELs), a heterogeneous T cell population with cytotoxic and regulatory properties, which can be imprinted on CD4+ T cells at the epithelium. However, the role of the T cell receptor (TCR) in this process remains unclear. Single-cell transcriptomic analyses revealed distinct clonal expansions between cell states, with CD4-IELs being one of the least diverse populations. Conditional deletion of TCR on differentiating CD4+ T cells or of MHCII on intestinal epithelial cells prevented CD4-IEL differentiation. However, TCR ablation on differentiated CD4-IELs, or long-term cognate antigen withdraw, did not affect their maintenance. TCR re-engaging of antigen-specific CD4-IELs during Listeria monocytogenes infection did not alter their state but correlated with reduced bacteria invasion. Thus, local antigen recognition is an essential signal for differentiation of T cells at the epithelium but differentiated CD4-IELs are able to preserve an effector program in the absence of TCR signaling.
