Texte intégralAntigen recognition by T cell can lead to immunity but also to antigen-specific T-cell tolerance. Immunological tolerance can be induced experimentally and may be useful for the treatment of organ-specific autoimmune diseases such as autoimmune diabetes. In this work, I have investigated the mechanisms of activation and tolerance induction in mature CD4+ and CDS+ T cells from TCR-transgenic mice. Systemic administration of soluble peptide is remarkably efficient to induce peripheral T-cell tolerance in vivo. Although one single injection induced transient T-cell tolerance, chronic intravenous (i. V. ) injections of soluble peptide is able to maintain CD4+ T-cell tolerance for more than 12 weeks. I have also shown that i. V. Injection of soluble peptide can tolerize naive CDS+ T cells but can also target effector CDS+ T cells thereby blocking the progression of an ongoing CDS-mediated autoimmune diabetes. Importantly, CDS+ T cell infiltrates are eliminated without bystander tissue damage. Furthermore, I have demonstrated that i. V. Injection of soluble MHC class I : peptide complexes represent an alternative strategy to induce CDS+ T cell tolerance in vivo. Tolerance was achieved by deletion and anergy of antigen-specific CDS+ T cells and allow to down-regulate an ongoing CDS mediated autoimmune diabetes. In experiments conducted in vitro with naïve T cells from TCR-transgenic mice, we have shown that antigen recognition by CD4+ T cells rapidly induced cytoskeletal alterations that are crucial for calcium responses and proliferation. Under conditions in which equal numbers of specific MHC class Il :peptide complexes are presented by dendritic cells (DC) and B cells, we could demonstrate that DC are always more efficient antigen presenting cells underlying the importance of adhesion/costimulatory molecules abundantly expressed by DC. Moreover, we provide evidence for the induction of small calcium signals in CD4+ T cells interacting with DC in the absence of specific antigen that involve MHC/TCR interactions. Finally, we have shown that naive CDS+ T cells can be fully activated and differentiated after antigenic stimulation in the absence of co-stimulatory signals. Altogether, these data contribute to our understanding of the mechanisms of activation and tolerance induction of CD4+ and CDS+ T cells

Texte intégralMono ADP-ribosyl transferases (ART) catalyse a posttranslational modification of proteins by transferring the ADP-ribose moiety of NAD to targets proteins. We investigated the functions of this newly identified proteins family and the effects of they substrate, extracellular NAD, on T lymphocytes. Exposure of T cells to micromolar NAD concentrations triggers rapid induction of apoptosis. This phenomenon requires the presence of ART2. 2 and of a functional P2X7 ATP receptor. ART2. 2-catalysed cell surface protein ADP-ribosylation activates the cytolitic P2X7 purinoreceptor causing pore formation and cell death. Interestingly, much lower NAD than ATP concentration are required to activate P2X7. In vivo, NAD concentration increases in inflamed tissue as a consequence of tissue injury. Based on the results that only peripheral naive T cells are sensitive to NAD, we proposed that NAD would participate to the control of autoimmunty by killing naive T cells surrounding inflamed tissue thereby limiting the activation of bystander T lymphocytes
Rivera, Cifuentes Claudia Andrea. « Intraepithelial dendritic cells : origin and function ». Electronic Thesis or Diss., Université Paris Cité, 2021. http://www.theses.fr/2021UNIP5167.
Texte intégralDendritic cells (DCs) patrol tissues and transport antigens to lymph nodes to initiate adaptive immune responses. Within tissues, DCs constitute a complex cell population made of distinct subsets that can exhibit different activation states and functions. How tissue-specific cues orchestrate DC diversification remains elusive. Particularly, the small intestine (SI) Lamina Propria (LP) is enriched in a peculiar population of cDC2s expressing the integrins CD103 and CD11b. Interestingly, a fraction of these cells can transmigrate into the epithelial layer both at steady state and in higher proportion upon infection. However, the consequences of such event on the identity and fate of these cells is unknown. By using single cell RNAseq analysis, we found that their epithelial colonization deeply modifies their transcriptomic profile, downregulating inflammatory genes expression and stimulating the transcription of antimicrobial genes. We then further described that the small intestine includes two pools of cDC2s originating from common preDC precursors: (1) lamina propria CD103+CD11b+ cDC2s that are mature-like pro-inflammatory cells and (2) intraepithelial cDC2s that exhibit an immature-like phenotype and induce tolerogenic T lymphocyte properties. Intraepithelial cDC2 phenotype results from the action of food-derived retinoic acid (ATRA), which enhances actomyosin contractility and promotes LP cDC2 transmigration into the epithelium. There, cDC2s are imprinted by environmental cues including ATRA itself and the mucus component Muc2. Hence, by reaching distinct sub-tissular niches, DCs can exist as immature and mature cells within the same tissue, revealing a novel mechanism of DC functional diversification

Texte intégralDendritic cells (DCs) have a central role in immunity and induce both specific immunity and immune tolerance thanks to their surface pathogen receptors (PPRs). The immune tolerance induced by tolerant DCs (Tol-DCs) appears as an interesting way to explore in order to improve the long-term transplantation outcome. Four DC subsets, at least, have been identified including conventional DCs (BDCA-1; BDCA-3), plasmacytoid DCs (pDC), Inflammatory DCs(MoDC) and Langerhans cells (LC). For each DC subset, an array of pathogen recognition receptors (PRRs) have been identified on their surface. The PRRs profile differs between DC subsets providing an individual responsiveness to target specific pathogens as well as to trigger and modulate immunological responses. The aim is to target DC subset PRRs by bispecific antibodies (BsAb) in order to induce physiological tolerance. Monocyte derived DC (moDC) and monocyte derived Langerhans DC (moLC) were obtained from CD14+ cells. The plasmacytoïd DC (pDC) were purified from an enriched DC cells fraction obtained by Percoll® gradient of PBMCs. The moDC, pDC and moLC subsets were analyzed by phenotype labelling and FACS. A Bispecific Ab (tandem scFv) were built to target PRR on DC subsets. The tandem is made of 2 scFv of 55KDa. The BsAb were produced using insect S2 (BIC05) or CHO cell (BIC15 or BIC25) and purified by protein L column. Each scFV recognize a PRR on DC. Each BsAb have been evaluated on its DC target and on PBMC at the phenotypic and functional levels by evaluating the maturation markers (CD83, CD86, CD25 and HLA-DR), cytokine secretions (IL-10, IL-12p70 and IFN- ) and the capacity to activate naïve T-cell as well as to induce regulatory T-cell (Treg)

Texte intégralThe first part of this work showed, in an original mice model, that regulatory CD4+ T cells play an important role in preventing peripheral CD8+ T cell-mediated autoimmunity. We suggest that regulatory CD4+ Foxp3+ T cells induce the generation at the periphery of regulatory CD8+ T cells that can then regulate conventional CD8+ T cells activity. The second part of this work suggests strongly that self-recognition events are required to control autoreactive, potentially pathogenic, conventional T cells. Autoreactivity would thus be necessary for its own control
