Peripheral blood T helper cells circulate with pathogenic tissue resident T helper cells in chronic GVHD

Project description:Chronic graft versus host disease (cGVHD) is a systemic autoimmune-like syndrome. The role of Tph cells in the pathogenesis of cGVHD has not been examined, although previous studies have shown that cGVHD is characterized by loss of Tfh cells. Here, we show that in cGVHD patients and in a murine model that reflects characteristic features of human cGVHD, the proportions of Tph cells among CD4+ T cells in the blood were expanded. These cells augmented memory B cell differentiation and production of IgG via IL-21. Adoptive transfer experiments showed recirculation between Tph in the blood and tissue-resident T helper (Trh) cells in GVHD target tissues. The TCR repertoires of blood Tph cells and Trh cells in GVHD target tissues of mice were highly overlapping.

Transcriptional profiling for lung tissue-resident helper T cell and spleen follicular T cells

Project description:We reported hybrid CD4+ T cell population following influenza viru infection. The hybrid CD4+ T cells exhibit both tissue residency and follicular helper T cell features. To further charaterization, we sorted lung tissue-resident helper T (TRH or TTH) cells (CD45iv-CD4+CD44+GITR-PD1hiFR4hi), non-TRH (CD45iv-CD4+CD44+GITR-PD1lowFR4low), spleen follicalar helper T (TFH) cells (CD4+CD44+GITR-PD1hiCXCR5hi) and non-TFH cells (CD4+CD44+GITR-PD1lowCXCR5low). Then the cells were applied for RNA sequencing. At the resut, we showed tissue-residency related genes are highly enriched in lung TRH but not spleen TFH cells. And The lung TRH cells express higher levels of TFH-related genes than lung-non TRH cells. Therefore, we suggest TRH cells play a role as tissue-resident helper T cells.

Characterization of lung tissue-resident helper T cells

Project description:To identify the characters of tissue resident CD4 T cells following influenza virus infection, we sorted lung CD45iv-CD4+CD44hi T cells from influenza PR8 infected mice (28 d.p.i.). Then the cells were performed single cell RNA sequencing. At the result, we found clera 5 differnt clusters and each cluster represent different helper T cell types including TH1, TH17 and Treg. One cluster exhibited both tissue residency and TFH cell features. So, we identify the characters of this hybrid lung CD4 T cells.

Tc17 cells are a pro-inflammatory, plastic lineage of pathogenic CD8+ T-cells that induce GVHD without anti-leukemic effects

Project description:IL-17-producing cells are important mediators of graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). Here we demonstrate that a distinct CD8+ Tc17 population develops rapidly after SCT but fails to maintain lineage fidelity such that they are unrecognizable in the absence of a fate reporter. Tc17 differentiation is dependent on alloantigen presentation by host-DC together with IL-6. Tc17 cells express high levels of multiple prototypic lineage-defining transcription factors (e.g. RORgt, T-bet) and cytokines (e.g. IL-17A, IL-22, IFNg, GM-CSF, IL-13). Targeted depletion of Tc17 early after transplant protects from lethal acute GVHD, however Tc17 cells are non-cytolytic and fail to mediate graft–versus–leukemia (GVL) effects. Thus, the Tc17 differentiation program during GVHD culminates in a highly plastic, hyper-inflammatory, poorly-cytolytic effector population which we term inflammatory Tc17 (iTc17). Since iTc17 mediate GVHD without contributing to GVL, therapeutic inhibition of iTc17 development in a clinical setting represents an attractive approach for separating GVHD and GVL.

Glycolytic metabolism of pathogenic T cells enables early detection of GvHD by 13C-MRI.

Project description:Graft-versus-host disease (GvHD) is a prominent barrier to allogeneic hematopoietic stem cell transplantation (HSCT). Definitive diagnosis of GvHD is invasive and biopsies of involved tissues pose a high risk of bleeding and infection. Our previous studies in a chronic GvHD mouse model demonstrated that alloreactive CD4+ T cells are distributed to target organs ahead of overt symptoms, meanwhile CD4+ T cell activation is tied to increased glycolysis. We aimed to compare the gene expression of allogeneic (mismatched) naive (Tn) and effector memory (Tem) CD4+ T cell subsets early post transplant. Specifically, we hypothesized that allogeneic CD4 effector memory T cells would show upregulated expression of genes related to glycolysis. We found that almost all enzymes of glycolysis were upregulated in effector memory CD4 T cells compared to naive cells, including transporters for glucose. In contrast, enzymes of the tricarboxylic acid cycle were not uniformly elevated.

Human resident memory T cells exit the skin and mediate systemic Th2-driven inflammation.

Project description:To investigate the transcriptional profile of human circulating T cells with skin tissue-resident memory phenotype (cTRM) in GVHD we performed bulk RNA sequencing from SMART-seq2 of sorted human cTRM (CD3+ CD4+ CLA+ CD103+) and conventional T cells (CD3+ CD4+ CD103-), and single cell RNA sequencing from 10X Genomics of sorted human CD45+, both from isolated blood PBMCs of patients with active acute GVHD.
