Texto completoPrimary immunodeficiencies, or inborn errors of immunity, are a group of disorders caused by monogenic mutations in genes playing a key role in the development and function of the immune system. In this thesis, a multiomics approach was taken to study two genes associated with these conditions, further elucidating the mechanisms by which pathogenic variants impair the immune system. The first subject was HYOU1, defined as a gene whose defects cause primary immunodeficiency. We observed hypogranularity in the patient's neutrophils and revealed a maturation arrest in the B cell lineage before the pro-B cell stage. The second subject was ITGAL, a potential candidate gene not previously described in relation to primary immunodeficiencies. We demonstrated that the studied variant is inherited in an autosomal recessive pattern, and pathway analyses revealed impairment of multiple adhesion and motility-related pathways. Moreover, we showed an elevation in the expression of other integrins, suggesting a compensatory response to counterbalance the defective integrins

Texto completoThe association between primary immune deficiency (PID) and autoimmunity may seem paradoxical when PID is considered only as an immune response defect against pathogens and autoimmunity only as an excess of immunity. Nevertheless, far from being simple immune defects increasing the risk of infections, DIPs are frequently associated with autoimmunity. Even more, autoimmunes manifestations can sometimes reveal a PID. Thus, epidemiological data from registers or large series of patients with PIDs agree on an overall prevalence of 25 to 30% of autoimmune complications (with auto-immune cytopenias as first causes). Several hypotheses have been proposed with different underlying mechanisms to explain the tolerance breakdown in PIDs. We can cite : 1°) a severe disturbance of lymphocyte homeostasis, for example in severe combined immunodeficiencies ; 2°) an impaired B-cell developpement with earlystage defects of tolerance ; 3°) a dysregulation of T cells (developpement or activation impairments) ; 4°) a dysfunction of T-reg (or B-reg) ; 5°) an excess of production of proinflammatory cytokines. These hypotheses are especially true for early-onset PIDs (in infancy). In this work (PhD), we explore the mechanisms of tolerance breakdown involved in adults PIDs. We use several approaches to describe the pathways leading to autoimmunity, focusing on the most common PID in adult : CVID (common variable immunodeficiency). This syndrome is not well defined on the genetic and physiopathological level. It is still a therapeutic challenge when complicated by autoimmunity (requiring immunosuppressive therapy)

Texto completoImportance: Most children with primary immunodeficiencies (PID) now reach adulthood. Assessment of their long-term health status represents a major challenge. We aimed to gain insight into how PID affects patient health status and quality of life (QoL). Design: The French Reference Center for PIDs (CEREDIH) initiated a prospective multicenter cohort which enrolled participants who met all inclusion criteria: (1) patient with PID included in the CEREDIH registry, (2) clinical diagnosis before 18 years, (3) alive and living in France. Among 1810 patients eligible for inclusion (on 1/17/2016), 1047 were children, and 763 were adults. A severity score was assigned to each health condition: grade 1 (mild) to grade 4 (life-threatening/disabling). We report the health status of children by focusing on two endpoints: grade 4 conditions and grade 3 or 4 conditions. Results: In the adult study, only 12% of adults with PID had never experienced severe or life-threatening conditions, and 7.6% of patients had been diagnosed with cancer. Furthermore, adults reported significantly lower scores for all domains of QoL, and QoL was strongly associated with poor health conditions. In the pediatric study, the response rate was 62.5%. Of the 656 children participants, 83% experienced at least one grade 3 or 4 condition. Children with PID scored significantly lower for most QoL domains. QoL was strongly associated with heavy burden of health conditions. Conclusions: Taken together, these studies demonstrate that the deleterious health effects bore by patients with PID become heavy since childhood, emphasizing the need to establish multidisciplinary healthcare teams, from childhood

Texto completoInnate lymphoid cells (ILCs) are recently identified components of the immune system, but their functions in vivo in humans are still elusive. In a first study, we show in patients with common variable immunodeficiency that non-infectious inflammatory complications and severe bacterial infections were more frequent in patients with severe NK cell lymphopenia, indicating potential non-redundant immune functions of NK cells when the adaptive immune response is not optimal. In a second study, we observe that in patients with ɣc and JAK3 severe combined immunodeficiencies, all ILC subsets are absent. After hematopoietic stem cell transplantation, ILCs remain indetectable with no susceptibility to disease, suggesting that ILCs might be redundant and dispensable in humans, if T and B cells functions are preserved. In the second part of this thesis, we study phenotypic and functional modifications of NK cell compartment in primary immune thrombocytopenia. Interferon gamma production by the peripheral blood NK cells of ITP patients is decreased. In contrast, splenic NK cells of ITP patients tend to be more efficient in antibody-dependent cell cytotoxicity. Intravenous polyvalent immunoglobulins lead to the inhibition of blood NK cell activation. Finally, we present the preliminary results of a study investigating the modifications of circulating ILCs in IgG4-related disease, and present an extensive litterature review concerning the role of ILCs in inflammatory diseases. In conclusion, the apparent redundancy of ILCs for protective immunity and their pathogenic role in inflammatory diseases make their targeting in humans for therapeutic purposes particularly promising

Texto completoHuman populations are exposed to infectious agents such as bacteria, fungi, viruses and parasites on a daily basis without developing any disease. However, a minority of individuals will suffer from infections to some microbes that are usually non-pathogenic to man, or will undergo severe and/or recurrent diseases usually easily treatable for others. This means that there is variability among individuals regarding their immune system, underlined by genetics between susceptible and resistant individuals. Two types of primary immuno deficiencies with a Mendelian mode of inheritance have been described. The first known as the classical primary immunodeficiency and is monogenic and predisposes in general to infections with a broad spectrum of infectious agents (one gene, multiple infections). The second type is also monogenic but predisposes generally to infections limited to a particular group of pathogens (one gene, one type of infection). The aim of my doctoral research was to characterize two new immunodeficiencies. First I highlighted a new physiopathological mechanism of the NEMO protein, a regulator of NF-κB pathway. This defect is characterized by normal protein expression and folding, but a specific defect of NEMO’s ubiquitin binding, which is an essential mechanism for the activation and regulation of the NF-κB pathway. This demonstrates that normal expression and structure of the protein do not exclude a pathological role of NEMO mutations in EDA-ID. I also described a new immune deficiency affecting the respiratory burst pathway in granulocytes which specifically confers a selective susceptibility to pyogenic bacterial infections. We studied a patient who was born from consanguineous parents, and who suffered from recurrent infections of the upper respiratory tract and cellulitis to S. epidermidis. By a genetic approach involving linkage analysis and exome sequencing, I identified a rare homozygous mutation (V484M) in the gene encoding for the NRAMP1 protein that co segregates with the disease with an autosomal recessive transmission. Specifically, this mutation impairs NRAMP1 protein expression in granulocytes, while expression remains normal in other phagocytic cells. NRAMP1 deficiency impairs both the respiratory burst and control of in vitro infection by S. aureus in granulocytes. Therefore, we identified the first NRAMP1 human deficiency. The mutation selectively affects granulocytes and is clinically responsible for pyogenic infections. This study helps to delineate the role of NRAMP1 in immunity against pyogenic bacteria through its involvement in reactive oxygen species production in granulocytes
