Full textThe Human Immunodeficiency Virus (HIV) genomic RNA is multifunctional. It acts both as a genome that is packaged within virions and as messenger RNA translated to yield the Gag and Gag-Pol polyproteins. The translation of these proteins relies exclusively on the cellular translation machinery and is initiated through two mechanisms: the canonical cap-dependent initiation pathway and the use of internal ribosome entry sites (IRESes). HIV-1 has two IRESes, one located within the 5' UTR (5' UnTranslated Region) that is stimulated during the G2/M phase of the cell cycle, and the other embedded within the Gag polyprotein coding region. The later drives translation initiation from two AUG in frame and results in the production of the full-length Gag protein but also of an additional N-terminally truncated Gag isoform. Few things are known about this isoform, but the mutation of the second AUG causes a significant decrease in the rate of viral replication. The structural and functional conservation of Gag IRES among lentiviruses suggests an important role of this isoform and thus of the IRES in the viral cycle. Our work aims to understand at a molecular level the host-pathogen relationships in the translation of the viral messenger RNA. My work focused on the roles of the 40S ribosomal subunit and of the cellular helicase DDX3 in the translation initiation of Gag. During the first part of my Phd, I studied the interaction between the 40S ribosomal subunit and HIV-1Gag IRES. Following complementary approaches, we evidenced two distinct ribosome binding sites present close to the two the initiation sites of Gag. Then, we evaluated the effect of each 40S binding site deletion on Gag translation efficiency, both in vitro and in cellulo (in collaboration with the team of T. Ohlmann, CIRI-ENS-Lyon). Taken together, our results confirm the functional relevance of the two ribosomal binding sites to ensure optimal production of the two Gag isoforms. The second part of my Phd project aims to define the role of DDX3 in the translation initiation of Gag. DDX3 is a RNA DEAD-box helicase involved in many cellular processes such as cell cycle regulation and the innate immune response but also in all aspects of RNA metabolism such as transcription, splicing, mRNA nuclear export and translation. Recently DDX3 has been shown to favor HIV-1 Gag translation. To define its role, we first purified a recombinant form of the protein and performed kinetic experiments to analyze its biochemical properties. Contrary to what has been previously described, MBP-DDX3 displays a strictly RNA-dependent ATPase activity with kinetic constants similar to those displayed by its yeast counterpart Ded1p. We next evaluated MBP-DDX3 helicase activity towards RNA duplexes or RNA/DNA hybrids, with different length and single strand overhangs. Our preliminary results indicate that DDX3 alone is sufficient to enhance Gag translation in our in vitro system which paves the way to fine biochemistry experiments such as reconstruction of functional initiation complexes assembled onto Gag RNA and evaluation of its role on Gag RNA structure

Full textThe epidemiology of sexually transmitted infections (STIs) is poorly documented in Mayotte especially among pregnant women (PW) and knowledge of determinants that increased STI in the island, and in this particular socio-economic and health situation, is needed. The objectives of this study were to estimate the frequency and risk factors associated with HIV, HBV, and syphilis, to study the HBV vaccination and describe the knowledge, attitudes, beliefs and behaviors related to HIV/AIDS-STIs in PW. A prospective cross-sectional study was conducted among 671 PW followed in Mayotte public prenatal clinic (Protection Maternelle et Infantile (PMI)) services. No case of HIV seropositivity was observed. The prevalence of HBsAg of HBV was 3.4% and of active syphilis was 2.1%, but the prevalence of HBV infection and HBV vaccination was respectively 35.5% and 18.6%. The HBV infection was associated with birthplace (Comoros), behavioral factors and history of STIs. Syphilis was rather associated with lack of education and history of STIs. The HBV vaccination was associated with sociodemographic determinants. The socio-behavioral study showed that there is a good knowledge of HIV/AIDS-STIs in PW despite the practice of some risky sexual behaviors. This work has helped to draw up an update of HIV and STIs, and their determinants among PW in Mayotte, and could lead to the development of prevention methods adapted to this context

Full textHIV infection is associated with a defect of humoral response. T follicular helper cells (Tfh) support multiple steps of B cell maturation and antibody production. My work was divided in two complementary axes aiming to characterize Tfh and memory B cell responses in HIV-infected patients.I identified several Tfh populations in HIV+ and HIV- spleens by FACS. These three populations were increased in HIV+ spleen. I also evidenced an impact of HIV infection on transcriptional profile and a compromised production of B cell differentiation-related cytokines by splenocytes from HIV+ donors. These results suggest Tfh functions impairment during HIV-infection. In parallel, we noticed an altered maturation of B cells in HIV+ spleens. In a cohort study, we compared memory B cell responses in the blood of Elite controllers (EC) who naturally control HIV and treated HIV+ patients. I evidenced that EC naturally preserve their memory B cell compartments. In contrast to anti-HIV IgG2 and IgG3 secreting B cells, most EC exhibit a high frequency of anti-HIV IgG1 secreting B cells. My work highlights a defective Tfh differentiation, which might explain why B cell maturation is severely affected in HIV-progressors. The status of HIV-controller seems associated with the presence of an IgG1 B cell memory response. Further work will highlight whether Tfh functions are preserved in EC

Full textTRBP (TAR RNA Binding Protein) is a cellular RNA binding protein that facilitates the replication of Human Immunodeficiency Virus type 1 (HIV-1). Isolated for its ability to bind HIV-1 TAR sequence present at the 5' end of all HIV-1 RNA, TRBP promotes HIV-1 replication at a post-transcriptional level by counteracting the antiviral activity of the protein kinase R (PKR).To gain more insight on how TRBP enhances HIV-1 replication, TRBP associated factors were purified using tandem immunoaffinity purification and identified by mass spectrometry. In addition to already known associated factors, a new protein with a putative RNA 2'-O-methyltransferase activity (2'OMTases) was copurified: FTSJ3. In higher eukaryotes, cellular mRNA are methylated on 2'-O ribose position on the first (Cap 1) and second nucleotide (Cap 2). This capping provides a molecular signature for the discrimination of endogenous versus exogenous mRNA. In the cell, MDA5, a cytoplasmic sensor, recognizes exogenous uncapped RNA and activate type I interferons (IFNs) production to establish an antiviral state. To evade innate immune response, some viruses have evolved mechanisms to mimics cap 1/2.HIV-1 does not encode a 2'O-MTase activity. However, owing to its interaction with TRBP, FTSJ3 is recruited at the 5' end of the viral genome and methylates TAR RNA in vitro. When capped by FTSJ3, TAR does not induce type I IFNs anymore when transfected in monocytic cell line U937. Conversely, HIV-1 viruses produced in FTSJ3 knock-down cells triggers type I IFNs expression through MDA5 sensing. This virus is attenuated, expressed in low amounts because of a block at the level of HIV-1 nuclear import. This study shows that FTSJ3 is recruited to HIV-1 5' end TAR sequence by TRBP and facilitates HIV-1 replication. HIV-1 RNA capping allows HIV-1 escape from MDA5 sensing and type I IFN induction. This study highlights a new way of HIV-1 escape from innate immune system

Full textInforming research participants is a fundamental ethical principle. . While information delivered during the inclusion in research has been described in numerous recommendations and guides, initiatives for providing general information during the course of research are more rarely considered whereas it represents a duty to respect the participants. When it exists, post-inclusion information is mainly seen in terms of return of the overall results at the end of the research. In some contexts, such as cohorts and long-term studies, the need to disclose general information during the course of research, in order to keep participants informed of the progress of the research and its developments, begins to emerge. The goal of this study was to explore the viewpoints of patient representatives, research professionals and patient groups affected by the question of information after inclusion, in the context of two cohorts of HIV-infected patients (AQUITAINE and COPILOTE) from the French Agency for Research on AIDS and Viral Hepatitis (ANRS). Face to face semi-direct interviews were conducted with 1) members of the TRT-5 group, a coalition of HIV patient associations working close with the ANRS to improve access to research information; 2) professionals of two cohorts (AQUITAINE and COPILOTE) identified with the help of the principal investigators and 3) a representative of the ANRS designated by the head of the agency. The interviews were fully transcribed and citations that may highlight clues to improving the process of information are reported. Patient groups were interviewed by questionnaire. Eleven patient representatives; 16 professionals (principal investigators, clinicians, researchers and the representative of the ANRS) and 134 patients agreed to participate. A qualitative analysis of interviews was conducted and compared to patient’s responses to the questionnaire. The results showed that written information is a relevant tool which: 1) helps to palliate the perceived lack of information; 2) participates in the education of participants; 3) helps to distinguish between the care and the research and 4) motivates professionals to communicate about research. Despite this relevance, written information should not be a substitute for verbal information, but should complete the latter. Oral information helps, indeed, to better address the heterogeneous nature of participants' expectations. This work supports the idea that the development of tools aiming the delivering of general information on ongoing research, even if it does not necessarily correspond to the preferred approach of participants, is essential to show them respect, to stimulate their interest and commitment in research and finally to initiate spoken information from professionals. Although the specific context of the work (the participants are patients followed by professionals in the field of medical care) makes it difficult to generalise the results, it is believed that it is essential to share initiatives and empirical studies such as that carried out here to better understand the content of information that can, or should be issued during the research and its dissemination. This must indeed be balanced with the difficulties of developing such information for professionals
