Project description:Opportunistic oral infections are ultimately presented in a vast majority of HIV-infected patients, often causing debilitating lesions that also contribute to deterioration in nutritional health. Although appreciation for the role that the microbiota is likely to play in the initiation and/or enhancement of oral infections has grown considerably in recent years, little is known about the impact of HIV infection on host-microbe interactions within the oral cavity. In the current study, we characterize modulations in the bacterial composition of the lingual microbiome in patients with treated and untreated HIV infection. Bacterial species profiles were elucidated by microarray assay and compared between untreated HIV infected patients, HIV infected patients receiving antiretroviral therapy, and healthy HIV negative controls. The relationship between clinical parameters (viral burden and CD4+ T cell depletion) and the loss or gain of bacterial species was evaluated in each HIV patient group. Characterization of modulations in the dorsal tongue (lingual) microbiota that are associated with chronic HIV infection.

Project description:Collectively, viruses are the principal cause of cancers arising in patients with immune dysfunction, including HIV+ patients. Kaposi’s Sarcoma (KS) etiologically linked to KSHV continues to be the most common AIDS-associated tumor. The involvement of oral cavity represents one of the most common clinical manifestations of this tumor. HIV infection incurs an increased risk for periodontal diseases and oral carriage from a variety of pathogenic bacteria. In the current study, by using 16S rRNA based pyrosequencing, we found that oral shedding of KSHV altered oral microbiota signature in HIV+ patients which may contribute to virus-associated malignancies development.

Project description:Despite a successful antiretroviral therapy (ART), adolescents living with perinatally acquired HIV (PHIV) experience signs of B-cell hyperactivation with expansion of 'namely' atypical B-cell phenotypes, including double negative (CD27-IgD-) and termed age associated (ABCs) B-cells(T-bet+CD11c+), which may result in reduced cell functionality, including loss of vaccine-induced immunological memory and higher risk of developing B-cells associated tumors. In this context,perinatally HIV infected children (PHIV) deserve particular attention, given their life-long exposure to chronic immune activation.

Project description:In perinatal HIV infection, early ART initiation is recommended but questions remain regarding infant immune responses to HIV and impact of HIV on immune development. Using single cell transcriptional and phenotypic analysis we evaluated the T cell compartment at pre-ART initiation of infants with perinatally acquired HIV from Maputo, Mozambique (TARA cohort). CD8+ T cell maturation subsets exhibited altered distribution in HIV exposed infected (HEI) infants relative to control infants (HIV exposed uninfected) with reduced naïve, increased effectors, higher frequencies of activated T cells, and lower frequencies of cells with markers of self-renewal. Additionally, a cluster of CD8+ T cells identified in HEI displayed gene profiles consistent with cytotoxic T lymphocytes (CTL) and showed evidence for hyper expansion. Longitudinal phenotypic analysis revealed accelerated maturation of CD8+ T cells was maintained in HEI despite viral control. The results point to a HIV directed immune response that is likely to influence reservoir establishment.

Project description:We sought to determine how gene expression changes during the first two years of HIV-1 infection among participants from HIV-1 serodiscordant couple cohorts from sub-Saharan Africa. This study included whole blood samples from 26 participants who did not have HIV-1 at study enrollment, had a steady sexual relationship with a partner with HIV-1 and acquired HIV-1 during follow-up. Most participants had samples from before and after infection.

Project description:A majority of individuals infected with human immunodeficiency virus (HIV) have inadequate access to antiretroviral therapy and ultimately develop debilitating oral infections that often correlate with disease progression. Our study evaluates the potential of simian immunodeficiency virus (SIV) infected rhesus macaques to serve as a non-human primate model for oral manifestations of HIV disease. Microarrays were used to characterize changes in gene expression in the tongue mucosa that occur during chronic SIV infection. Dorsal tongue tissues from healthy uninfected macaques and macaques with chronic stage SIV infection were used for RNA extraction and hybridization on Affymetrix microarrays.
