Testo completoTitle : Development of new animal models to study the pathophysiology of RA and the role of methotrexate-induced tolerance.Keywords : Rheumatoid arthritis, shared epitope, ACPA, immunogenicity, methotrexate, TNF inhibitorsAbstract: Rheumatoid arthritis (RA) is an autoimmune disease (AID) where antibodies directed against citrullinated peptides (ACPA) are highly specific for the diagnosis. One of the key treatments of RA is methotrexate. It has an action on both the disease and reinforces the effect of second line TNF inhibitors (TNFi). MTX might act via prevention of anti-drug antibodies (ADAb) directed against TNFi that are implicated in loss of efficacy of TNFi. We have developed a macaque model to recapitulate the human disease by immunization with citrullinated peptides in the context of a genetic factor favoring RA: the shared epitope on the HLA. Immunization of macaques with citrullinated peptides and intra-articular boost cause an anti-citrulline T and B cell response and a chronic monoarthritis.The role of MTX-induced tolerance against TNFI has been studied in autoimmune BAFF transgenic (tg) mice using MTX just before treatment with TNFi we were able to prevent ADAb formation in BAFFtg mice and not wild type mice or macaques. We identified that BAFFtg mice expressed elevated CD73 leading to more adenosine and regulatory B cells as actors in MTX-induced tolerance. This MTX-BAFF interaction was further confirmed in humans in the ABIRISK cohort where MTX was more efficient to prevent ADAb formation in RA patients with elevated BAFF levels.Setting up two new animal models allows better understanding of RA pathophysiology and better use of biologics that extend to other domains of medicine

Testo completoElevated expression of ‘B cell activating factor’ (BAFF), a potent B cell survival factor contributes to the expansion of low-affinity self-reactive B cells during the establishment of tolerance. However, mechanisms leading to BAFF over-expression in autoimmune diseases are not understood. We reported the discovery of a new variant for BAFF, 4BAFF in humans (in which exon 4 is excised) or 5BAFF in mice (in which exon 5 is excised), which acts as a transcription factor of the full-length form of BAFF, and which is preferentially found in cells isolated from patients with autoimmune diseases. When transfected in human B cells, D4BAFF upregulates a large number of genes associated with immune response and especially innate immunity and regulation of apoptotis. Furthermore D4BAFF acts, in association with p50 from the NF- B pathway, as a transcription factor for its own parent gene. Another important finding is that 4BAFF is an important component of the efficacy of regulatory B cell activity. Our work introduces an entirely novel concept in biology suggesting that a human cytokine gene can be transcriptionally regulated by the activity of one of its own splice variants.We have also tried to understand the complexity of the various forms of BAFF. We observed that epithelial cells expressed BAFF-receptor (BR3) and produce BAFF suggesting autocrine properties. Blocking BR3 results in nuclear translocation of PKC promoting epithelial cell apoptosis.Furthermore, only some forms of BAFF are required for epithelial cell survival. Finally, we studied the consequences of the expression of TLR9 on the B cell surface and demonstrated that TLR9 acts as a co-receptor of the B cell receptor to influence B cell fate independently of CpG binding. We show that CpG activation of B cells, acting synergistically with BCR signals, was inhibited by anti-TLR9 stimulation. Induction of CD25 expression and proliferation of B cells were thus down-regulated by engagement of cell surface TLR9. Overall, our results indicate that TLR9 expressed on B cell plasma membrane might be a negative regulator of endosomal TLR9, and could provide a novel control by which activation of autoreactive B cells is restrained. All these findings contribute to a better understanding on immunopathology of autoimmune diseases with potential applications in therapy

Testo completoAccelerated atherosclerosis is now recognized as the main cause of death in SLE patients. Of note, the increased prevalence of premature atherosclerosis in SLE is not fully explained by traditional cardiovascular risk factors. Although we and others showed that lupus immunopathogenesis may promote accelerated atherosclerosis, the mechanisms by which SLE pathogenesis might contribute to accelerate atherosclerosis remains elusive.B cells, by their ability to produce pathogenic autoantibodies, play a causative role in SLE. Consistently, there are strong evidence to connect B-cell activating factor (BAFF), a cytokine required for maturation and survival of B2 B cells, to lupus. Belimumab (GSK), a monoclonal antibody specifically directed against BAFF, is the only approved biotherapy for SLE treatment. BAFF is involved in atherosclerosis and atherosclerosis-prone mice in which hematopoietic cells did not express the receptor for the pro-B2 BAFF cytokine displayed a significant reduction in atherosclerotic lesion development. My thesis project consists of studying the contribution of BAFF in accelerated atherosclerosis associated with SLE.We first showed that ApoE-/-D227K mice were an appropriate model for the study of lupus associated atherosclerosis, when compared to the ApoE-/- pristane treated mice.We then demonstrated that, in the ApoE-/-D227K model, the neutralization of BAFF by using an antibody specifically targeting this cytokine, efficiently treated lupus by inducing the depletion of mature B cells in the secondary lymphoid organs. On the other hand, the atheroprotective effect of the BAFF neutralization, despite the depletion of B cells in the aortic tertiary lymphoid organs, was apparent in mice with low cholesterol levels, only. For high cholesterol levels, the neutralization of BAFF tended to aggravate atherosclerotic lesions by promoting the foam cell transformation of macrophages that expressed TACI.We then asked whether the observations made in our mouse model were relevant to human atherosclerosis associated with SLE and observed a positive correlation between BAFF serum levels, peripheral expansion of B lymphocytes and progression of subclinical atherosclerosis in lupus patients at apparent low risk for cardiovascular events. The effect of Belimumab treatment on atherosclerosis was also analyzed ex vivo and in vitro in a small number of patients and we showed that BAFF neutralization in lupus could enhance or dampen the development of atherosclerosis according to the body mass index (BMI).In conclusion, our work shows 1- that B cells and BAFF play a pathogenic role in atherosclerosis associated with lupus and 2-that BAFF can be atheroprotective or atheroaggravative depending on the mechanisms involved. In absence of classical cardiovascular risk factors (such as dysplipidemia or overweight), BAFF neutralizing therapy, by disrupting the BAFF/BAFFR interaction on B cells, depletes mature B cells in tertiary lymphoid organs and is atheroprotective. In the presence of classical cardiovascular risk factors, BAFF neutralizing therapy, by disrupting the BAFF/TACI interaction on macrophages, promotes the foam cell transformation of macrophages and aggravates atherosclerosis

Testo completoSystemic sclerosis (SSc) is a rare autoimmune disease characterized by skin fibrosis and occasionally pulmonary fibrosis. We first assessed the role of BAFF, a cytokine involved in B cell maturation, in bleomycin-induced pulmonary fibrosis in mice. We showed that BAFF was increased in response to bleomycin and that BAFF-/- mice or BAFF-R-Igtreated mice are protected from pulmonary fibrosis. Then, we assessed whether B cells and BAFF could regulate collagen production by skin fibroblasts isolated from SSc patients. We demonstrated that B cells increase collagen production and cytokines involved in skin fibrosis. The addition of BAFF increases the effect of B cells on fibroblasts. Lastly, we studied the regulation of BAFF expression by microRNAs. Our results show that miR-30a*, d* and e* directly target the BAFF mRNA

Testo completoPar cette approche, nous avons mis en évidence un rôle essentiel des membres de la famille BAFF/APRIL et de leurs récepteurs (BCMA, BAFF-R et TACI) dans la biologie du MM. Les cellules de MM expriment les récepteurs alors que les ligands sont principalement produits par les cellules de l'environnement médullaire. L'utilisation d'un inhibiteur spécifique de BAFF/APRIL a permis de montrer que ces facteurs de croissance sont importants pour la survie et la prolifération des cellules tumorales. TACI apparaît être le récepteur principal pour médier l'effet de BAFF et APRIL dans le MM. Une forte expression de TACI par les cellules de MM est associée à une signature génique de plasmocytes matures alors que les plasmocytes tumoraux présentant une faibles expression de TACI ont une signature génique de plasmablastes proliférants. Nous avons montré que syndecan-1, un protéoglycane à chaînes héparane sulfate joue un rôle essentiel dans la biologie du MM en permettant l'accumulation de fortes concentrations de facteurs de croissance à la surface des cellules. Nous avons identifié que syndecan-1 joue un rôle de corécepteur pour APRIL et TACI supportant ainsi la croissance des cellules de MM.
Ces travaux offrent de nouvelles perspectives thérapeutiques pour le MM et ont débouché sur un essai clinique de phase I/II, au CHU de Montpellier, utilisant un inhibiteur de la voie BAFF/APRIL dans le MM.

Testo completoPrimary Sjögren’s Syndrome (pSS) is a systemic autoimmune disease characterized by sicca symptoms and a broad variety of systemic manifestations. The most severe complication of the disease is the development of non-Hodgkin’s lymphoma (NHL) in 5% of patients. Recent evidence indicates a major contribution of B cells. In this work, we developed clinical and basic research subjects, related to the role of B-cell in the pathogenesis of pSS. In the first section, we showed that memory B-cell infiltrates are present in pSS and may be used as an additional diagnostic and follow-up tool. In the second section, we showed that high serum levels of the cytokine called FLT3-L (a cytokine implicated in B-cell ontogenesis and lymphoproliferation) are associated with abnormal B-cell distribution, characteristic of pSS; and disease clinical activity. In addition, this cytokine may explain the development of lymphoma. In the third section, we demonstrated that ∆4BAFF (a new variant of BAFF, due to the alternative splicing of exon 4) is a transcription factor of its own gene. Interestingly, this new variant is mainly detected in autoimmune diseases and its expression is regulated by IFN-y and SC35 protein (one of the proteins implicated in the splicing machinery). This finding provides an expanded conceptual view of BAFF gene regulation in autoimmune diseases, and contributes to a better understanding of the mechanisms involved in BAFF up-regulation in autoimmunity. Collectively, these results are of clinical and fundamental basic interest in pSS, in the diagnostic, physiopathology and therapeutic contexts

Testo completoHIV-1 (Human Immunodeficiency Virus I) infection is characterized by persistent viral replication, chronic immune activation, CD4+ T cell depletion and several immune dysfunctions that are observed even in cells that are not targeted by the virus such as B lymphocytes. Some B-cell abnormalities observed in HIV-1-infected individuals include hypergammaglobulinemia, nonspecific B-cell activation, class switching, increased cell turnover, breakage of tolerance as well as a loss of the capacity to generate and maintain memory, among others. Several cytokines and growth factors that are increased in the serum of HIV-1-infected individuals have been suggested to directly and/or indirectly trigger B-cell activation, and one of these is the B-cell-activating factor (BAFF). BAFF is an essential component of B-cell homeostasis but excess production results in B-cell hyperplasia, lymphoproliferation, hypergammaglobulinemia, and symptoms of autoimmunity. The mechanisms of BAFF upregulation in the context of HIV-1 infection are not fully understood and no previous studies have addressed the ability of fully competent HIV-1 to induce BAFF production by myeloid cells. The different studies presented in this thesis converge to the general objective of better characterizing the mechanisms underlying BAFF upregulation by primary human monocytes and monocyte-derived macrophages in the context of HIV-1 infection. We show here that HIV-1 drives BAFF secretion in monocytes by a type-I interferon (IFN)-dependent process. Moreover, we identified plasmacytoid dendritic cells (pDCs) as the cellular source of this type-I IFN-directed modulatory effect in our monocyte cultures, demonstrating that a pDC/monocyte interplay is required for the HIV-1-induced BAFF production. In addition, we provide evidence that HIV-1 upregulates BAFF production in monocyte-derived macrophages and this process relies on productive virus infection, which is itself influenced by the cell phenotype status, and is independent of Toll-like receptors and type-I IFN signal transduction as well as the action of Nef. Altogether, this doctoral project provides new insights for the increased BAFF levels observed during HIV-1 infection. These findings might be relevant for the design of therapies that could help restore the functionality of the B-cell compartment in HIV-1-infected individuals.

Testo completoThe maintenance of mature peripheral B cells depends on at least two survival cues, tonic signaling from the B cell receptor (BCR) complex and the extracellular cytokine B cell activating factor of the TNF family (BAFF). In addition to enhancing viability, BAFF controls the functional efficiency of the peripheral B cell pool by regulating complex physiological processes including cell growth, metabolism, energy homeostasis and entry into the cell cycle. BAFF-mediated induction of two molecular mechanisms, namely activation of the Akt signal transduction pathway and upregulation of the oncogenic kinase Pim-2 results in the modification of effector proteins including transcription factors and regulators of protein synthesis which are capable of executing the observed cellular physiological changes. The classic protein kinase C beta is instrumental in BAFF-induced Akt-activation and PKC beta-deficient B cells and mice show signs of partial refractiveness to BAFF. The protein tyrosine kinase Syk plays a role in early B cell development and is activated in mature B cells by immunogenic BCR-stimulation. Inducible ablation of Syk in mice results in the loss mature B cells from the peripheral lymphoid organs and reveals an indispensable function for Syk in tonic BCR survival signaling.

Testo completoPrevious data suggested that the monoclonal anti-CD20 antibody induced paradoxically the settlement of autoreactive splenic long-lived plasma cells (LLPC) in the spleen of patients with auto-immune cytopenia, explaining the treatment failure. To investigate whether this process had a general relevance and decipher its mechanism, we used the AID-CreERT2-EYFP mouse model, which allows the irreversible expression of EYFP in B cells engaged in an immune response after tamoxifen regimen to follow plasma cells at different times after immunization. When analyzed by multiplex PCR at the single-cell level, while the splenic EYFP+B220-PC of untreated mice displayed an intermediate profile between short-lived and long-lived PC, the PC from anti-CD20 treated mice composed a more mature homogeneous population, similar to the long-lived bone marrow PC. The absolute number of splenic EYFP+B220-PC did not change significantly upon anti-CD20 treatment indicating that B-cell depletion promoted PC differentiation rather than a long-lived PC selection. BAFF (B-cell activating factor) and CD4+ T-cells played a major role in plasma cell survival since combination of anti-CD20 with anti-BAFF or anti-CD4 antibodies dramatically reduced the number of splenic EYFP+B220- LLPC. Anti-CD20 treatment also promoted the differentiation of LLPC in the spleen in the lupus prone NZB/W model, while a treatment combining anti-CD20 with anti-BAFF induced a marked reduction in total splenic PC numbers. These results suggest that the process of PC maturation upon anti-CD20 treatment is a general mechanism and that interfering with anti-BAFF antibody at the time of B-cell depletion might greatly improve the response rate in auto-immune disease

Testo completoSjögren's syndrome (SS) is a systemic autoimmune disease (AID) characterized by the presence of autoantibodies expressed by autoreactive B cells (anti-SSA, anti-SSB and rheumatoid factor) associated with lesions of exocrine glands leading to dry eyes and mouth BAFF is a cytokine responsible for autoreactive B cells survival that is involved in pathogenesis of various AID. Objective We studied BAFF involvement in SS both in peripheral blood and in minor labial salivary glands. Results We observed: 1. An increase in BAFF serum level correlated with rheumatoid factor titer in patients with SS. 2 An increase in BAFF staining among T cells and epithelial cells labial salivary glands and salivary epithelial cells. 3. BAFF production by labial salivary epithelial cells, increased under interferon-alpha (IFNa) and -gamma stimulation and greater increase in BAFF production by epithelial cells from patients than controls under INFa. 4. A similar increase in BAFF production by peripheral blood monocytes from patients with SS under IFNa stimulation. 5. An increase in expression of BAFF in peripheral blood T cells from patients with SS. 6. An increase in BAFF serum level and BAFF mRNA level in peripheral blood mononuclear cells from patients after rituximab infusions. Conclusion BAFF play a key role in SS pathogenesis. BAFF increase seems to be related to IFNa in SS and is therefore a interesting therapeutic target in this disease, especially after rituximab infusions

Testo completoIn this thesis, we studied the expression, the effect and the signaling pathways of these two Systems TWEAK/FN14 and APRIL, BAFF/BCMA, TACI and BAFFR in normal and pathological skin and in the liver. We have shown that TWEAK by binding to its receptor Fn 14 induces cell cycle arrestinG2/M phase and translocation of AIF from mitochondria to the nucleus, inducing apoptosis of keratinocytes. This apoptosis is caspase and cathepsin B independent. We showed that the receptors TACI and BCMA are expressed in adult human epidermis, while the receptor BAFFR is absent. APRIL and/or BAFF bind BCMA trigger the activation of NF-kappaB and production of inflammatory proteins IL-6 and GM-CSF. The binding of APRIL to BCMA induce a cell cycle arrest in G2/M phase and decrease cell proliferation of hepatocellular carcinoma. This induces the phosphorylation of JNK and increased transcription of transcription factors FOXO3 andGADD45. Our data suggest that TWEAK/FN14 and APRIL,BAFF / BCMA, TACI, BAFFR could potentially be targets, markers or interesting tools in the therapy of certain diseases (inflammatory tumor) in different tissues

Testo completoChronic lymphocytic leukemia (B-CLL) is due to the accumulation of B lymphocytes deficient in apoptosis. NOS-II expressed by these cells produces NO which protects them from apoptosis. We have shown that resveratrol and some polyphenols derivatives, as well as flavopiridol, exert an apoptotic activity on B-CLL, correlated to an inhibition of NOS-II expression and of NO production. We study also genes modulation by NOS-II inhibition in patients' leukemic cells and the identified genes are currently under thorough investigation. Finally, we have shown that BAFF and APRIL proteins are abnormally expressed on B-CLL cells surface and favour their survival. Moreover, a BAFF soluble form is detected by SELDI-TOF in patients serums, more importantly than in normal individuals. BAFF and APRIL aberrant expression induces the existence of a survival autocrine loop in B-CLL
