Texto completoThailand is an endemic area for chronic HBV infection. Despite implementation of HBV vaccination, perinatal HBV transmission remains a major cause of chronic infection. This study aimed at identifying HBV mutants that may be associated with vaccine failure, misdiagnosis of chronic HBV infection and antiviral treatment failure. The dissertation is divided in three parts. In the first part, we analyzed the prevalence of perinatal HBV transmission in a large HIV prevention cohort in Thailand and characterized the HBV vaccine escape mutants. Among 3,349 HIV-infected pregnant women, 7% were found HBsAg positive. Eleven children born to HBsAg-positive mother were found HBsAg-positive at 2–18 months of age. Complete series of samples were available for 9 mother-child pairs. Based on direct sequencing and cloning analysis, 3 patterns of transmission were observed : i) transmission of wild-type variants from mothers with high HBV DNA level, ii) transmission of maternal minor variant and iii) transmission of variants already present in maternal blood samples. The capacity of HBV variants to escape from anti-HBs neutralization in vitro will be further studied using HBV-pseudoviral particles harboring the characterized mutations

Texto completoHepatitis C infection (HCV) concerns 10% to 30% of HIV patients. The aim of our research was to explore the influence of HCV co infection in HIV patients with data from the French Pharmacovigilance database and from a regional cohort of HIV and coinfected patients. We showed that hepatic or haematological troubles occurred more frequently in coinfected patients. In the cohort study, clinical and immunological worsening of HIV infection seems to be faster in co infected patients, despite the lack of statistically significant difference. This work underlines the differences in the therapeutic management of the HIV and HIV+HCV patients (ARV drugs, modifications or withdrawal of ARV drugs). The risk of the occurrence of hepatic or haematological troubles with ARV drugs is a possible explanation. The cohort should be continued to increase the number of patients included

Texto completoChronic hepatitis C virus (HCV) infection is common in patients with human immunodeficiency virus (HIV). HIV-HCV Co-infection is associated with more severe and more rapid progression of HCV, leading to increased incidence of fibrosis, cirrhosis, and end-stage liver disease. Our work is devoted to the description of HIV-HCV co-infected patients (2006-2008). We also evaluated the prevalence and factors associated with liver steatosis in these patients. Lastly, we addressed the issue of the non-invasive assessment of liver fibrosis. The management of HIV-HCV co-infected patients should comprise a systematic screening of liver steatosis. The assessment of liver fibrosis using two non-invasive tests (eg Fibroscan-Apri, Fibroscan-Fibrotest) should be considered. In case of discordance between the results of these tests, a liver biopsy must be performed

Texto completoMacrophages are both crucial host effector cells for HIV-1 and important leukocytes involved in viral pathogenesis. For my doctoral thesis, I was interested in further characterizing the role of macrophages in HIV-1 pathogenesis, and during co-infection with Mycobacterium tuberculosis (Mtb), the etiological agent for tuberculosis (TB). I first participated in a study that provided evidence that HIV-1 infection reprograms the migration of macrophages, particularly by triggering the protease-dependent migration mode. This effect was mediated by the interaction of the viral protein Nef with the host proteins Hck and WASP, which leads to modification in the organization and proteolytic activity of podosomes, important structures for protease-dependent migration. The higher migration capacity of HIV-1-infected macrophages translated in vivo by an increase in the recruitment of macrophages in several tissues of Nef-transgenic mice. This work revealed a novel mechanistic understanding of how HIV-1 infection drives macrophages into tissues, contributing to viral dissemination and possibly creating a hidden cellular reservoir of virus. Worsening this public health issue posed by the HIV-1 epidemic is the frequent association of the virus with Mtb. Indeed, Mtb aggravates HIV-1 pathogenesis in co-infected individuals. Yet, the mechanisms involved in this process are still poorly understood, including the contribution of macrophages. To investigate how Mtb exacerbates the HIV-1 infection in human macrophages was the main focus of my thesis. First, I revealed that Mtb-infected macrophages generate a microenvironment that drives bystander macrophages towards phenotypic and functional features of the so-called M(IL-10) anti-inflammatory program. I found that these M(IL-10) macrophages are highly efficient for HIV-1 production. I demonstrated that the TB-associated microenvironment induces the formation of macrophage-to-macrophage connecting tunneling nanotubes (TNTs) through the IL- 10/STAT3 axis, a phenomenon that is responsible for the dramatic increase of HIV-1 production in M(IL-10) macrophages. Moreover, I provided evidence that M(IL-10) cells are expanded in the peripheral blood of co-infected patients and accumulate in the lungs of co-infected non-human primates. Altogether, this central part of my PhD thesis sheds light to TNTs as key players in the aggravation of HIV-1 pathogenesis in human macrophages during co-infection with Mtb. Thus, this cellular mechanism (together with the IL- 10/STAT3 axis) could represent an unexpected target to develop novel therapeutics against AIDS/TB co-morbidity. Collectively, the results obtained during my thesis contribute to a better understanding of the role of macrophages during HIV-1 pathogenesis and their ability to disseminate the virus in a mono-infection context, or during co-infection with Mtb

Texto completoMycobacterium tuberculosis (Mtb), the bacteria causing tuberculosis (TB), and the human immunodeficiency virus type 1 (HIV-1), the etiological agent of acquired immunodeficiency syndrome (AIDS), act in synergy to exacerbate the progression of each other in co-infected patients. While clinical evidence reveals a frequent increase of the viral load at co-infected anatomical sites, the mechanisms explaining how Mtb favours HIV-1 progression remain insufficiently understood. Macrophages are the main target for Mtb. Their infection by the bacilli likely shapes the microenvironment that favours HIV-1 infection and replication at sites of co-infection. To address this issue, I took advantage of an in vitro model mimicking the TB-associated microenvironment (cmMTB, "conditioned media of Mtb-infected macrophages") previously established in the laboratory; a model that renders macrophages susceptible to intracellular pathogens like Mtb. Upon joining the team, I participated in the study on how Mtb exacerbates HIV-1 replication in macrophages, using this model. We found that cmMTB-treated macrophages (M(cmMTB)) have an enhanced ability to form intercellular membrane bridges called tunneling nanotubes (TNT), which increase the capacity of the virus to transfer from one macrophage to another, leading to the exacerbation of HIV-1 production and spread. The principal objective of my PhD thesis was to identify novel factors that are involved in the exacerbation of HIV-1 replication in macrophages in the context of tuberculosis. To this end, a transcriptomic analysis of M(cmMTB) was conducted, and revealed two key factors: the Siglec-1 receptor and type I interferon (IFN-I)/STAT1 signaling. The first part of my PhD thesis dealt with the characterization of Siglec-1 as a novel factor involved in the synergy between Mtb and HIV-1 in macrophages. First, I demonstrated that its increased expression in M(cmMTB) was dependent on IFN-I. Second, in Mtb and simian immunodeficiency virus co-infected non-human primates, I established a positive correlation between the abundance of Siglec-1+ alveolar macrophages and the pathology, associated with the activation of the IFN-I/STAT-1 pathway.
