In vivo CRISPR screening in autoimmune disease model reveals differential dependence of Th1 and Th17 cells on amino acid transporter SNAT1

ABSTRACT: Purpose: The aim of this experiment was to determine the effect of SNAT1 loss on Th1 and Th17 cells. Methods: SNAT1 was knocked out using CRISPR/Cas9 in primary CD4+ T cells polarized to Th1 and Th17 cells in vitro. RNA was then isolated for RNAseq. n=3 biological replicates. Results: SNAT1 mRNA expression was significantly reduced in both Th1 and Th17 cells. Th1 cells displayed consequent changes in the mRNA expression of many other genes (with particular decrease in the expression of glycolysis pathways genes), while Th17 cells had no significant changes in the expression of all other mRNAs detected. Conclusion: This study demonstrates the differential dependence of Th1 and Th17 cells on the amino acid transporter SNAT1.

P2X7 signaling drives Th1 cell differentiation through metabolic reprogramming for aerobic glycolysis

Project description:This study provides evidence on the molecular mechanisms by which P2RX7 signaling promotes Th1 cell differentiation. P2RX7 induces T-bet expression and aerobic glycolysis in splenic CD4+ T cells that respond to malaria, at a time prior to Th1/Tfh polarization. Cell-intrinsic P2RX7 signaling sustains the glycolytic pathway and causes bioenergetic mitochondrial stress in activated CD4+ T cells. We also show in vitro the phenotypic similarities of Th1-polarized CD4+ T cells that do not express P2RX7 and those in which the glycolytic pathway is pharmacologically inhibited. In addition, ATP synthase blockade in vitro and the consequent inhibition of oxidative phosphorylation, which forces cells to use aerobic glycolysis, is sufficient to promote rapid CD4+ T cell proliferation and polarization to the Th1 profile in the absence of P2RX7. These data demonstrate that P2RX7-mediated metabolic reprograming for aerobic glycolysis is a key event for Th1 cell differentiation and suggest that ATP synthase inhibition is a fundamental mechanism by which P2X7 signaling induces the Th1 response.

Effects of Th1- and Th17-derived factors on microglia.

Project description:There is evidence that microglia interact with infiltrating Th1 and Th17 cells and this interaction results in mutual activation. However, the potential of a distinct cytokine milieu generated by these effector T cell subsets to activate microglia is poorly understood. In this study, we tested the ability of factors secreted by Th1 and Th17 cells to induce microglial activation. Interestingly, we found that only Th1-associated factors had the potential to activate microglia while the Th17-associated factors as well as direct contact of Th17 cells with microglia only had a minimal effect. Further Th1-derived factors triggered a proinflammatory M1-type gene expression profile in microglia Microglia harvested from mixed glial cultures were treated with supernatants from Th1- or Th17 cultures. Microglia cultured in medium was used as controls. At 16h post treatment RNA was isolated from the microglia and probed on AgilentÂ´s murine 4x44k microarrays. RNA isolated from four independent experiments were used for the gene expression profiling. Microglia, Th1, Th17

The antitumor function of Th17-derived Th1 cell is better than traditional Th1 and Th17 cells

Project description:Th17 cells have better stemness and differentiation potential, and under certain circumstances, they can be stimulated to differentiate into other subcelltypes including Th1 and Treg. Here, we report that compared to traditional Th1 and Th17 cells, Th17-derived Th1 cells had greater anti-tumor activity. Both C57 mice ACT therapy and CAR-T therapy models were used to validate it. Mechanism: Th17-derived Th1 cells are able to express Th1 effector molecules as well as retain a lower level of exhaustion than Th1 cells. Additionally, it has a higher amount of type 1 interferon response and a stronger capacity for migration. Our research offers a fresh perspective on how ACT therapy and CAR-T therapy might develop in the future.

Essential role for CD30-Transglutaminase 2 axis in memory Th1 and Th17 cell generation.

Project description:Memory helper T (Th) cells are crucial for secondary immune responses against infectious microorganisms but also drive the pathogenesis of chronic inflammatory diseases. Therefore, it is of fundamental importance to understand how memory T cells are generated. However, the molecular mechanisms governing memory Th cell generation remain incompletely understood. Here, we identified CD30 as a molecule heterogeneously expressed on effector Th1 and Th17 cells, and CD30hi effector Th1 and Th17 cells preferentially generated memory Th1 and Th17 cells. We found that CD30 mediated signal induced Transglutaminase-2 (TG2) expression, and that the TG2 expression in effector Th cells is essential for memory Th cell generation. In fact, Cd30-deficiency resulted in the impaired generation of memory Th1 and Th17 cells, which can be rescued by overexpression of TG2. Furthermore, transglutaminase-2 (Tgm2)-deficient CD4 T cells failed to become memory Th cells. As a result, T cells from Tgm2-deficient mice displayed impaired antigen-specific antibody production and attenuated Th17-mediated allergic responses. Our data indicate that CD30-induced TG2 expression in effector Th cells is essential for the generation of memory Th1 and Th17 cells, and that CD30 can be a marker for precursors of memory Th1 and Th17 cells.

Retinoic acid signaling constrains the plasticity of Th1 cells and prevents development of pathogenic Th17 cells [Affymetrix experiments]

Project description:CD4+ T cells differentiate into phenotypically distinct T-helper cells upon antigenic stimulation. Regulation of plasticity between these CD4+ T-cell lineages is critical for immune homeostasis and prevention of autoimmune diseases. However, the factors that regulate lineage stability are largely unknown. Here we investigate a role for retinoic acid (RA) in the regulation of lineage stability using T helper 1 (Th1) cells, traditionally considered the most phenotypically stable Th subset. We found that RA, through its receptor RARa, sustains stable expression of Th1 lineage specifying genes as well as repressing genes that instruct Th17 cell fate. RA signaling is essential for limiting Th1 cell conversion into Th17 effectors and for preventing pathogenic Th17 responses in vivo. Our studies identify RA-RARa as a key component of the regulatory network governing Th1 cell fate and define a new paradigm for the development of pathogenic Th17 cells. These findings have important implications for autoimmune diseases in which dysregulated Th1-Th17 responses are observed. IFN-gamma+ Th1 cells from IFNgeYFP reporter mouse; comparing dnRARa to WT
