[Ab] Resumo:For group-living primates, social organization hinges upon multiple factors, including group size, group cohesion, and the group's age and sex composition. Fission-fusion dynamics reduce the risks of living in a large group, which can include feeding competition related to the seasonality of resources. Here we report on the group dynamics (i.e. formation of parties) of a population of red-capped mangabeys (Cercocebus torquatus) located in Sentier Nature forest, South Loango National Park, Gabon, and examine the role of fruit availability in episodes of fission-fusion and shifting range use during the peak fruiting season of 2014. To assess fission-fusion dynamics, we obtained data on party type (i.e. number, size and age-sex composition), the effect of availability of fruit from 4 tree species on the home range and habitat used by parties, and the periodicity of these processes. The results show that red-capped mangabeys displayed seasonal fission-fusion dynamics related to fruit availability during the season under study.

[Ab] Resumo:Infections with mycobacteria, including Mycobacterium tuberculosis (Mtb) and Mycobacterium bovis (M. bovis) BCG, are a leading cause of morbidity and mortality for HIV-infected persons. In contrast to HIV, nonpathogenic SIV infections of sooty mangabeys are characterized by a lack of clinical disease including an absence of opportunistic infections. The goal of this study was to identify innate immune responses to M. bovis BCG maintained during nonpathogenic lentiviral infections through a comparison of functional responses during pathogenic HIV or nonpathogenic SIV infections. Monocytes were evaluated for their ability to express key anti-mycobacterial cytokines TNF-α and IL-12 following a six-hour ex vivo BCG exposure. While HIV-infection was associated with a decreased percentage of IL-12-producing monocytes, nonpathogenic SIV-infection was associated with an increased percentage of monocytes producing both cytokines. Gene expression analysis of PBMC following ex vivo BCG exposure identified differential expression of NK cell-related genes and several cytokines, including IFN-γ and IL-23, between HIV-infected and control subjects. In contrast, SIV-infected and uninfected-control mangabeys exhibited no significant differences in gene expression after BCG exposure. Finally, differential gene expression patterns were identified between species, with mangabeys exhibiting lower IL-6 and higher IL-17 in response to BCG when compared to humans. Overall, this comparison of immune responses to M. bovis BCG identified unique immune signatures (involving cytokines IL-12, TNF-α, IL-23, IL-17, and IL-6) that are altered during HIV, but maintained or increased during nonpathogenic SIV infections. These unique cytokine and transcriptome signatures provide insight into the differential immune responses to Mycobacteria during pathogenic HIV-infection that may be associated with an increased incidence of mycobacterial co-infections.

[Ti] Título:The well-tempered SIV infection: Pathogenesis of SIV infection in natural hosts in the wild, with emphasis on virus transmission and early events post-infection that may contribute to protection from disease progression.

[Ab] Resumo:African NHPs are infected by over 40 different simian immunodeficiency viruses. These viruses have coevolved with their hosts for long periods of time and, unlike HIV in humans, infection does not generally lead to disease progression. Chronic viral replication is maintained for the natural lifespan of the host, without loss of overall immune function. Lack of disease progression is not correlated with transmission, as SIV infection is highly prevalent in many African NHP species in the wild. The exact mechanisms by which these natural hosts of SIV avoid disease progression are still unclear, but a number of factors might play a role, including: (i) avoidance of microbial translocation from the gut lumen by preventing or repairing damage to the gut epithelium; (ii) control of immune activation and apoptosis following infection; (iii) establishment of an anti-inflammatory response that resolves chronic inflammation; (iv) maintenance of homeostasis of various immune cell populations, including NK cells, monocytes/macrophages, dendritic cells, Tregs, Th17 T-cells, and γδ T-cells; (v) restriction of CCR5 availability at mucosal sites; (vi) preservation of T-cell function associated with down-regulation of CD4 receptor. Some of these mechanisms might also be involved in protection of natural hosts from mother-to-infant SIV transmission during breastfeeding. The difficulty of performing invasive studies in the wild has prohibited investigation of the exact events surrounding transmission in natural hosts. Increased understanding of the mechanisms of SIV transmission in natural hosts, and of the early events post-transmission which may contribute to avoidance of disease progression, along with better comprehension of the factors involved in protection from SIV breastfeeding transmission in the natural hosts, could prove invaluable for the development of new prevention strategies for HIV.

[Ab] Resumo:OBJECTIVE: Procolobus badius, Colobus polykomos, and Cercocebus atys are three West African primate species known to have distinctive feeding behaviors. Our objectives were (1) to test whether intra-taxon variation in bone mineral content exists between anterior and posterior regions of the mandible and (2) to determine if interspecific differences are interpretable via feeding and dietary idiosyncracies among the three taxa. DESIGN: Twenty-one mandibles from naturally deceased C. polykomos (n=7), P. badius (n=9), and C. atys (n=5) were scanned using cone beam computerized tomography. Alveolar bone (AB) and basal cortical bone (CB) of incisor (I1) and second molar (M2) regions were digitally isolated. Degree of bone mineralization (DBM) distribution was obtained using histograms of CT attenuation values. Mean, standard deviation (SD), the 5th (Low5) and the 95th (High5) percentiles of the DBM histogram were compared between the jaw regions in species. RESULTS: The mean and Low5 of DBM were significantly lower for AB than CB of all species (p<0.001). The AB DBM parameters were not significantly different between I1 and M2 of all species (p>0.056) except the mean of C. polykomos (p<0.05). The mean, SD, High5 of CB DBM at M2 of C. atys was significantly higher than those of C. polykomos and P. badius (p<0.006). CONCLUSIONS: The durophagous C. atys had higher CB DBM value at the M2 region than C. polykomos and P. badius, which supports the hypothesis that materially stiffer mandibular bone in C. atys can develop in response to the generation of high bite forces during hard object feeding.

[Ti] Título:Down-modulation of primate lentiviral receptors by Nef proteins of simian immunodeficiency virus (SIV) of chimpanzees (SIVcpz) and related SIVs: implication for the evolutionary event at the emergence of SIVcpz.

[Ab] Resumo:It has been estimated that human immunodeficiency virus type 1 originated from the zoonotic transmission of simian immunodeficiency virus (SIV) of chimpanzees, SIVcpz, and that SIVcpz emerged by the recombination of two lineages of SIVs in Old World monkeys (SIVgsn/mon/mus in guenons and SIVrcm in red-capped mangabeys) and SIVcpz Nef is most closely related to SIVrcm Nef. These observations suggest that SIVrcm Nef had an advantage over SIVgsn/mon/mus during the evolution of SIVcpz in chimpanzees, although this advantage remains uncertain. Nef is a multifunctional protein which downregulates CD4 and coreceptor proteins from the surface of infected cells, presumably to limit superinfection. To assess the possibility that SIVrcm Nef was selected by its superior ability to downregulate viral entry receptors in chimpanzees, we compared its ability to down-modulate viral receptor proteins from humans, chimpanzees and red-capped mangabeys with Nef proteins from eight other different strains of SIVs. Surprisingly, the ability of SIVrcm Nef to downregulate CCR5, CCR2B and CXCR6 was comparable to or lower than SIVgsn/mon/mus Nef, indicating that ability to down-modulate chemokine receptors was not the selective pressure. However, SIVrcm Nef significantly downregulates chimpanzee CD4 over SIVgsn/mon/mus Nefs. Our findings suggest the possibility that the selection of SIVrcm Nef by ancestral SIVcpz is due to its superior capacity to down-modulate chimpanzees CD4 rather than coreceptor proteins.

[Ti] Título:Characterization of the interactions between SIVrcm Vpx and red-capped mangabey SAMHD1.

[Ab] Resumo:SAMHD1 (SAM domain- and HD domain-containing protein 1) inhibits HIV-1 infection of myeloid cells and resting CD4+ T-cells. Two lineages of primate lentiviruses, the sooty mangabey SIV (simian immunodeficiency virus) (SIVsm)/macaque SIV (SIVmac)/HIV-2 lineage and the red-capped mangabey SIV (SIVrcm) lineage, carry a SAMHD1 antagonist called Vpx. Vpx recognizes SAMHD1 and recruits a ubiquitin E3 ligase complex that is composed of CUL4 (Cullin4), DDB1 (damaged DNA-binding protein 1) and a member of the DCAF (DDB1/CUL4-associated factor) family called DCAF1. This E3 ligase complex polyubiquitinates SAMHD1, which leads to proteasomal degradation of SAMHD1. As opposed to the well-characterized interaction of SIVmac Vpx with human SAMHD1 and DCAF1, SIVrcm Vpx adopts a different mode of interaction with SAMHD1 of red-capped mangabeys. In the present study, we have characterized the interactions that are essential for SIVrcm Vpx-mediated degradation of rcmSAMHD1 (red-capped mangabey SAMHD1). Using mutagenesis and molecular modelling, we have determined the key role of the W23LHR26 peptide of SIVrcm Vpx in recognizing rcmSAMHD1. The amino acids Phe15, Leu36, Phe52, Arg55 and Arg56 at the N-terminal domain (NtD) of rcmSAMHD1 are involved in interaction with Vpxrcm (red-capped mangabey Vpx). The molecular model of rcmSAMHD1-NtD, Vpxrcm and C-terminal domain (CtD) of DCAF1 (DCAF1-CtD) complex reveals further that rcmSAMHD1-NtD and Vpxrcm utilize an interaction interface that is different from that used by human SAMHD1-CtD and Vpxsm. These findings provide further insights into the different modes of interaction between Vpx and SAMHD1 as the result of the 'arms race' of virus and host cell.

[Ab] Resumo:Medium-to-large mammals within tropical forests represent a rich and functionally diversified component of this biome; however, they continue to be threatened by hunting and habitat loss. Assessing these communities implies studying species' richness and composition, and determining a state variable of species abundance in order to infer changes in species distribution and habitat associations. The Tropical Ecology, Assessment and Monitoring (TEAM) network fills a chronic gap in standardized data collection by implementing a systematic monitoring framework of biodiversity, including mammal communities, across several sites. In this study, we used TEAM camera trap data collected in the Udzungwa Mountains of Tanzania, an area of exceptional importance for mammal diversity, to propose an example of a baseline assessment of species' occupancy. We used 60 camera trap locations and cumulated 1,818 camera days in 2009. Sampling yielded 10,647 images of 26 species of mammals. We estimated that a minimum of 32 species are in fact present, matching available knowledge from other sources. Estimated species richness at camera sites did not vary with a suite of habitat covariates derived from remote sensing, however the detection probability varied with functional guilds, with herbivores being more detectable than other guilds. Species-specific occupancy modelling revealed novel ecological knowledge for the 11 most detected species, highlighting patterns such as 'montane forest dwellers', e.g. the endemic Sanje mangabey (Cercocebus sanjei), and 'lowland forest dwellers', e.g. suni antelope (Neotragus moschatus). Our results show that the analysis of camera trap data with account for imperfect detection can provide a solid ecological assessment of mammal communities that can be systematically replicated across sites.

[Ab] Resumo:BACKGROUND: By reshuffling genomes, structural genomic reorganizations provide genetic variation on which natural selection can work. Understanding the mechanisms underlying this process has been a long-standing question in evolutionary biology. In this context, our purpose in this study is to characterize the genomic regions involved in structural rearrangements between human and macaque genomes and determine their influence on meiotic recombination as a way to explore the adaptive role of genome shuffling in mammalian evolution. RESULTS: We first constructed a highly refined map of the structural rearrangements and evolutionary breakpoint regions in the human and rhesus macaque genomes based on orthologous genes and whole-genome sequence alignments. Using two different algorithms, we refined the genomic position of known rearrangements previously reported by cytogenetic approaches and described new putative micro-rearrangements (inversions and indels) in both genomes. A detailed analysis of the rhesus macaque genome showed that evolutionary breakpoints are in gene-rich regions, being enriched in GO terms related to immune system. We also identified defense-response genes within a chromosome inversion fixed in the macaque lineage, underlying the relevance of structural genomic changes in evolutionary and/or adaptation processes. Moreover, by combining in silico and experimental approaches, we studied the recombination pattern of specific chromosomes that have suffered rearrangements between human and macaque lineages. CONCLUSIONS: Our data suggest that adaptive alleles - in this case, genes involved in the immune response - might have been favored by genome rearrangements in the macaque lineage.

[Ab] Resumo:An accurate description of reproductive characteristics and ovarian endocrinology is necessary to address questions about the reproductive strategies and life history of a species and for meaningful, cross species analyses. Here we used analysis of fecal estradiol (fE) and behavioral observations to determine for the first time the reproductive characteristics and endocrinology of a wild group (N = 18 adult and 3 adolescent females) of Sanje mangabeys (Cercocebus sanjei). The study was conducted in the Udzungwa Mountains National Park, Tanzania, from October 2008 through September 2010. Average cycle length (±SD) was 29.3 ± 3.2 days in adults and 51.4 ± 5.5 days in adolescents. Menses appeared within 5.1 ± 2.1 days in adults and 4.8 ± 0.3 days in adolescents after the end of maximum tumescence, and lasted 6.7 ± 3.1 and 10.3 ± 5.0 days, respectively. Infant death tended to reduce the number of cycles to conception (4.3 ± 1.5 cycles after a surviving infant vs. 2.6 ± 1.0 cycles after infant death). Adolescents cycled for at least 16 months without conceiving. Implantation bleeding began 17.5 ± 0.7 days from the onset of detumescence, and lasted 10.0 ± 1.4 days. Gestation length averaged 171.8 ± 3.4 days. Postpartum amenorrhea lasted 6.7 ± 2.3 months while females whose infants had died resumed cycling within 14.3 ± 5.9 days. The interbirth interval after a surviving infant averaged 20.0 ± 4.3 months. These reproductive characteristics of the Sanje mangabey resembled those of other mangabeys and related cercopithecines, with the exception of an earlier onset and longer duration of menstruation and implantation bleeding. Further information on the physiology of the Sanje mangabey is needed to clarify what factors may cause the unusual characteristics of both, their menses and implantation bleeding.

[Ab] Resumo:Chronic lymphoplasmacytic gastritis in two red-capped mangabeys (Cercocebus torquatus) at a zoological facility progressed to severe hypertrophic gastropathy similar to Ménétrier's disease that affects humans. Clinical signs included emesis, diarrhea, hunched posture consistent with abdominal pain, anemia, and hypoproteinemia. Large gastric masses were present and in one case created a gastric outflow obstruction. Both cases were positive for simian immunodeficiency virus and Helicobacter spp. were variably isolated, although the association with the hypertrophic gastropathy is unclear. Medical treatment had varying success and included sucralfate, H2 receptor antagonists, proton pump inhibitors, diet manipulations, and antibiotic therapies targeting Helicobacter spp. Surgical resection of a large portion of the stomach resulted in some palliative improvement in one case. Overall, this disease presented many challenges regarding identification, confirmation of diagnosis, and clinical management. Both aggressive medical and surgical treatments were unrewarding for long-term management of hypertrophic gastropathy in this pair of red-capped mangabeys and resulted in a poor prognosis in these cases.
