Lambert, Caroline. "Les anticorps neutralisants contre l'infection des virus foamy simiens chez l'homme". Thesis, Sorbonne Paris Cité, 2016. http://www.theses.fr/2016USPCC328/document.
Testo completoSimian foamy virus (SFV) are the third family of exogenous complex retroviruses infecting humans. These viruses, of origins, are transmitted by body fluids (mainly saliva), through a direct contact between an individual and an infected m establish a chronic infection in the infected human host. To date, neither pathology, nor secondary transmission has be to be associated with SFV infection in humans. Therefore, SFV represents a natural model of restriction emerging simiar in humans. During my PhD, I characterized the humoral response against SFV in people living in Cameroon and Gabon, mainly infected bites during hunting episodes. I showed the presence of SFV neutralizing antibodies in the plasma of 48 infected individ titers. Our study population is infected with viruses of 2 different genotypes, which differ in the central region of the En region involved in binding to the cellular receptor.While in 60% of cases, neutralizing response was specific to a single genotype, 40% of cases showed cross-reactivity. Cr( was associated in 50% of cases with co-infection with viruses from both genotypes.In conclusion, my PhD is the first study to characterize neutralizing antibodies in individuals chronically infected with a zoonotic SFV : these antibodies are frequently detected at high titers and are directed against epitopes commonly found in chimpanzee and gorilla SFV

Testo completoThe enteric viruses are ubiquitous virus infecting a broad range of vertebrates, including humans and non-human primates (NHPs). They are spread by direct or indirect fecal-oral route following which they reach the enterocytes and multiply. Even though infections caused by these viruses are asymptomatic, enteric viruses could be responsible for frequent gastroenteritis in children under 5 years of age. These viruses may be responsible for severe pathologies such as respiratory, encephalitic, cardiac and neurological diseases. In the 1950s, many viruses have been isolated from NHPs species commonly used in cell culture and biomedical research. Since, many studies have been conducted to characterize, then enteric viruses have been mainly identified in captive NHPs or those living in close contact with humans. Little is known concerning the circulation, epidemiology and diversity of enteric viruses in the wild, except for enteroviruses and adenoviruses. The objective of this thesis is to investigate and characterize the enteric virus in NHPs of Central Africa. Thus from 600 samples of feces of NHPs collected in natural forests and reserves in Gabon, we highlighted the circulation of different species enteroviruses (EVs) in mandrills and chimps. We also identified EVs close to those infecting humans as well as two new serotypes in a chimpanzee and in a mandrill. We have highlighted an astrovirus (AstV) completely divergent from those referenced in a gorilla. Apart from their outstanding natural environment, enteric viruses are also present in NHPs in frequent contact with humans. Therefore fecal samples from a group of 12 chimpanzees from the Tchimpounga Sanctuary, we characterized the EV-C99 responsible for cases of paralysis in humans and probably responsible for that observed in a chimpanzee. In addition, two sapovirus (SaVs) very close to a SaV identified in humans have also been characterized. Central Africa is therefore characterized by a diversity of enteric virus circulating in NHPs. The identification in the wild of enteric virus in NHPs close to those infecting humans raises probability of cross-species transmissions between NHPs and humans whose sense remains to be determined. However in NHPs in the sanctuary, susceptibility to these human viruses can be responsible for severe diseases such as paralysis observed in chimpanzee

Testo completoSIV infecting chimpanzees and gorillas are the precursors of the Human Immunodeficiency Virus type 1. The four groups of HIV-1 are the results of four different viral transmissions from apes to humans. Using non invasive methods we discovered the reservoir of HIV-1 M and N in two communities of chimpanzees (Ptt) in Cameroon and found that Gorillas (Ggg) are infected by a SIV close to HIV-1 O and P. While SIVgor has not yet been detected in chimpanzees, phylogeny shows that Ptt transmitted this virus to Ggg. Using a multidisciplinary approach, we studied the characteristics of the infection in wild living gorillas. We prospected 13 sites in Cameroon and 3 in CAR. 2120 fecal samples of gorillas and 442 of chimpanzees were collected. SIVgor infection was detected in 3 sites in Cameroon and the prevalence ranges from 3.2% to 4.6%, lower than in chimpanzees. Several social groups of gorillas with overlapping home-ranges were infected and the prevalence within group could exceed 25%. Viruses of the same group are genetically close, showing epidemiologic links. In a follow up study between 2004 and 2009 on one site, we discovered a focus of infection with 2 cases of seroconvertion and we re-sampled one infected female 5 years after. In this site, the prevalence of SIVgor is stable and the number of infected females is higher than the males. The social structure of gorillas and their behavior can partly explain for the repartition and prevalence of SIVgor, as well as the differences with the infection in chimpanzees. This multidisciplinary study proves the feasibility of a follow up study in wild living gorillas. If SIVgor turns out to be pathogenic, a follow up will be essential for this endangered species

Testo completoEver since HIV has been discovered to be the pathogenic agent that causes AIDS in 1983, much progress has been made in the field. Two different viruses are now known to infect humans, HIV-1 and HIV-2. These two distinct viruses have many sub-types and clades representing a high diversity inter and intra-individuals (quasi-species). The finding of HIV simian counterparts, the Simian Immunodeficiency Viruses (SIVs), has broadened the knowledge of primate lentiviruses and to date forty-five species of non-human primates are known to be infected with SIVs in sub-saharan Africa. It is now clear that HIV-1 and HIV-2 epidemics are the result of zoonosis from chimpanzees/gorillas and sooty mangabeys, respectively. With such a big diversity of SIVs in the wild and a frequent contact of SIV infected monkey species with humans, it is interesting that so far, only two lineages breached the species barrier and infected human populations. To be able to correctly infect a cell, a lentivirus has to overcome the installed cellular barriers known as restriction factors while at the same time correctly exploiting the established host cellular machinery. Proteins such as TRIM5, APOBEC3, Tetherin/Bst2, SAMHD1 are able to restrict retroviral infections in certain conditions. In this thesis, it has been evaluated the role of TRIM5 proteins and other capsid interacting proteins with a scope to the eventuality of a cross-species transmission infection. The results showed that human TRIM5alpha does not restrict any of the primate lentiviruses tested, and so far, no primate lentivirus is known to be restricted by it. Cyclophilin A binding and dependence is variable depending on the SIV capsid; this interaction is widespread among the primate lentiviruses phylogenetic tree but not a universal phenotype. Different capsids from SIVs have been tested for the sensitivity to the depletion of nucleoporins that are known to be used by HIV-1 in its infection; it has been concluded that the same diversity applies to the interaction with RanBP2 and Nup153. Additionally, we identified a SIV capsid that is highly restricted in human cells; this phenotype was called Ref2. With the report of a possible correlation between HIV-2 capsid variations and different levels of progression to AIDS, we devised a study aiming to identify if TRIM5 proteins were involved in this phenotype. We concluded that human TRIM5alpha does not restrict any HIV-2 capsid obtained from a HIV-2 cohort, in which individuals were presenting different levels of progression to AIDS. However, we observed a different viral fitness that correlated with pathogenicity. Moreover, Cyclophilin A dependence seems ubiquitous among all of the tested HIV-2 capsids. All of these capsids are sensitive to RanBP2 depletion and the interaction is much likely mediated by RanBP2's C-terminal motif that shares a high homology with Cyclophilin A. Summing up, it is much likely that some SIVs that still circulate in the wild can hijack the same specific cellular co-factors as HIV-1 to produce a new epidemic in humans. TRIM5α does not seem to be a potent barrier to an eventual cross-species transmission from lower primates to humans, and Cyclophilin A interaction seems to play a major role to the infection of some SIVs

Testo completoAnaplasma phagocytophilum is an obligate intracellular alphaproteobacterium, mainly transmitted by Ixodes ticks. It is the causative agent of bovine and human granulocytic anaplasmosis and can infect various mammalian species, including rodents and wild ruminants. Several epidemiological cycles may coexist in Europe. In particular, human and bovine strains seem to belong to distinct cycles, which leads to the hypothesis that cattle strain are not zoonotic. Due to its intracellular location in vivo inside granulocyte neutrophils, A. phagocytophilum culture is challenging and leads to several methodological difficulties. This explains why few studies have so far been performed in order to explore the interactions between this bacterium and its host species (mammals and ticks). In order to investigate these interactions at different levels, I performed four complementary studies. First, our epidemiological study in cattle herd highlighted the genetic diversity of strains circulating in the herds and challenges the role of cattle as a reservoir for A. phagocytophilum. The infections of endothelial cells that we performed to study the role of these cells as niche cells and/or determinants of species barrier during A. phagocytophilum infection led us to consider that endothelial cells could host A. phagocytophilum during their transmission from dermis to blood, without allowing their multiplication. For studying A. phagocytophilum transcriptomic reactions during the transmission from tick to vertebrate host, we submitted infected tick cells to heat shocks. Our results suggest that few transcriptomic events are induced during this transmission. Nevertheless, A. phagocytophilum is able to respond to non-physiological heat stress. We identified differentially expressed proteins, which could play an important role during tick or mammal infection. The yeast two hybrid analysis allowed us to detect three host cell interactors to APH_0032, an A. phagocytophilum vacuolar membrane protein. This technique could be applied for studying the molecular interactions involving proteins that where differentially expressed during heat shock, for example. Finally, our four complementary studies raise the question of the basis for such genetic variability and host diversity within an obligate intracellular bacterium and open up a wide field of perspectives
