Full textFas (CD95/TNFRSF6), a type-I transmembrane receptor of the tumor necrosis factor receptor (TNFR) superfamily, is a well-known cell death activator. However, it has been also implicated in non-cell death processes including cell survival, differentiation, migration. Whereas the molecular cascade that initiates apoptosis upon Fas engagement with its ligand FasL is particularly well described, the informations concerning the molecular mechanisms underlying the Fas mediated non-apoptotic pathways are sparse.As indicated by the induction of autoimmunity and lymphoproliferation in ALPS patients harboringmutations in either the receptor or its ligand, the Fas/FasL system plays a major role in T cell immune homeostasis and thus, in the control of autoimmunity and cancer. On one side, the Fas mediated death has been described critical for (i) the deletion of autoreactive lymphocytes, and thus in the maintenance of peripheral tolerance; (ii) the control of the number of lymphocytes activated by weak antigens during pathogen infections.On the other side, and beyond cell death induction, some Fas non-death pathways have been described in T cells, among which the role of Fas as co-regulatory receptor for the TCR during its activation. Despite the potential importance of this role in immunotherapeutic strategies, only few and controversial studies related to this involvement were done. Indeed, whereas several studies have described Fas as a TCR co-stimulatory receptor, others defined an inhibition of T cell activation by Fas-TCR concomitant stimulation. In this context, the aim of my PhD project consisted into molecularly dissect the Fas-TCR co-signaling.By using both primary T cells and cell lines bearing a specific transgenic TCR, we could define Fas as a costimulatory receptor. By exploiting biochemical approaches as well as flow cytometry and microscopy we could decipher the Fas-TCR crosstalk both at functional and molecular level. First, we show that Fas-TCR costimulation occurs in both naïve and in memory T cells as well as in both CD4+ and CD8+ T cell subpopulations.Molecularly, we could describe that Fas enhances the TCR signaling at membrane proximal level, since the phosphorylation of the first proteins involved in TCR activation is increased. Furthermore, both membrane-bound and soluble FasL are capable to initiate Fas co-stimulatory signal. Lastly, we could exclude the involvement of FADD and Caspase-8, first actors of Fas signaling, in the co-activation, and even more importantly, the involvement of the death domain of Fas cytoplasmic tail, unveiling the implication of another Fas receptor domain. To describe the molecular mechanisms and the context where Fas-TCR co-stimulation occurs might be of an outstanding importance in the comprehension of Fas physiopathology in T cells and for future studies that might involve its potential for immunotherapeutic strategies

Full textUsing a new global approach referred to as TcLandscape, we previously observed that direct -type pathway of allorecognition was associated with a strong accumulation of V~ transcript without skewing of CDR3 length distribution. Such a pattern was also observed in vivo in acute rejection of cardiac allografts and in acute delayed rejection of " accommodated " cardiac xenografis in rats. In contrast, T cell infiltrating cardiac tolerated allografis showed an altered pattern of TCR V~ chain that might represent the molecular signature of regulatory T cells. This pattern allowed to attribute quantitative difference in the response of different T cell families. This quantitative/qualitative approach allowed to follow over time the effect of an immune-based therapy in HIV-1 infected patients vaccinated with a mixture of lipopeptides

Full textSignal transducer and activator transcription (STAT) proteins are essential transcription factors regulating gene expression involved in many biological functions especially immune responses. Here we report a patient with a de novo heterozygous missense mutation in STAT5B gene resulting in altered STAT5 transcriptional function. The patient presented with immune thrombocytopenia, lymphadenopathy, splenomegaly, an antibody class switching defect and granulocytosis with necrotizing granulomas. We found a specific dysregulation of CD4+ T cell subsets with an abnormal accumulation of effector memory T (TEM) cells. Transcriptome analysis in patient's T cells revealed a selective downregulation of the STAT5-dependent IL-2 signaling pathway. We found that TEM cells from the patient were resistant to in vitro TCR restimulation-induced cell death. These results demonstrate a key role of STAT5 in memory T cell homeostasis by regulating cell death during TCR restimulation

Full textDaxx (Death Associated protein) is a multifunctional adaptor protein involved in several signalling pathways. During my PhD, I studied the role of Daxx in T cell homeostasis, focussing on its role in Fas and TCR-CD3 signalling pathways. The activation of Fas pathway, by the engagement of the receptor Fas by its ligand, induces cell death. After activation, the proteins Fadd and Caspase 8 are recruited to Fas, forming the Death Inducing Signalling Complex (DISC). We have shown that, in T cells, Daxx is also recruited to Fas after activation, enhancing the DISC formation. In fact, in T cells in which Daxx has been abolished (by the overexpressing a dominant negative form of Daxx (Daxx-DN) or by siRNA technique) Fas-induced cell death is inhibited because of the impaired Daxx recruitment to the receptor, preventing DISC formation. On the other hand, the activation of TCR-CD3 signalling pathway by the antigen in T cells generates a signal inducing proliferation. The recruitment of the protein ZAP70 to the TCR-CD3 complex and its phosphorylation are initial steps of this pathway. We have shown that Daxx is also recruited to TCR-CD3 complex, what prevents the recruitment of phosphorylated ZAP70 to the signalling complex and so inhibits TCR-induced proliferation. Indeed, we have observed, in vivo and in vitro, that TCR-induced proliferation is increased in T cells in which Daxx has been abolished because of the impaired recruitment of Daxx to the TCR-CD3 complex, enhancing phosphorylated ZAP70 recruitment. All together, these results show that Daxx is a critical regulator element in T cell homeostasis
