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.

Microarrays were used to characterize changes in gene expression in the dorsal tongue epithelium that occur during chronic SIV infection. Epithelial cells were laser microdissected from dorsal tongue tissue sections from healthy uninfected macaques and macaques with chronic stage SIV infection and used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Cannabinoid administration before and after simian immunodeficiency virus (SIV)-inoculation ameliorated disease progression and decreased inflammation in male rhesus macaques. Δ9-tetrahydrocannabinol (Δ9-THC) did not increase viral load in brain tissue or produce additive neuropsychological impairment in SIV-infected macaques. To determine if the neuroimmunomodulation of Δ9-THC involved differential microRNA (miR) expression, miR expression in the striatum of uninfected macaques receiving vehicle (VEH) or Δ9-THC (THC) and SIV-infected macaques administered either vehicle (VEH/SIV) or Δ9-THC (THC/SIV) was profiled using next generation deep sequencing.

Project description:Rhesus macaques vaccinated by rhesus cytomegalovirus vectors expressing simian immunodeficiency virus proteins (RhCMV/SIV) activate gene expression signature associated with IL15. To examine the gene expression signature activated by IL15, we performed longitudinal examinations of rhesus macaques during IL15 treament.

Project description:Molecular basis for CNS dysfunction in simian immunodeficiency virus-infected rhesus monkeys. We used microarrays to identify differentially expressed genes in chronic simian immunodeficiency virus-infected rhesus monkeys. Frontal lobe samples were obtained from control and SIV infected animals for RNA extraction and hybridization on Affymetrix microarrays. We sought to better understand the gene that changes in gene expression with SIV infection in the frontal lobe.

Project description:Rhesus macaques (RMs) inoculated with live-attenuated Rev-Independent Nef¯ simian immunodeficiency virus (Rev-Ind Nef¯SIV) as adults or neonates controlled viremia to undetectable levels and showed no signs of immunodeficiency over 6-8 years of follow-up. We tested the capacity of this live-attenuated virus to protect RMs against pathogenic, heterologous SIVsmE660 challenges Blood PBMC Time after SIV infection: 2 weeks post SIV infection Infection:Rev-Ind Nef¯SIV

Project description:Salmonella enterica serotype Typhimurium cause a localized enteric infection in immunocompetent patients while human immunodeficiency virus (HIV)-infected patients develop a life threatening bacteremia. We used a rhesus macaque ileal loop model to study how simian immunodeficiency virus (SIV) infection triggers defects in mucosal barrier function that enhance S. Typhimurium dissemination. SIV infection resulted in significant depletion of CD4+ T cells in the intestinal mucosa. Gene expression profiling revealed a defective TH17 response (with suppression of IL-17 and IL-22 expression) and impaired homeostasis of the intestinal epithelium in SIV-infected animals during NTS infection. These findings correlated with an impaired ability of lamina propria CD4+ T cells from SIV-infected macaques to produce IL-17 upon ex vivo stimulation, while production of IFNï§ was not affected. This cytokine imbalance in SIV-infected animals was associated with reduced expression of genes required for intestinal epithelial maintenance and repair, increased fluid secretion during NTS infection, epithelial damage and translocation of a non-invasive S. Typhimurium mutant. Although no defects in neutrophil recruitment were noted, the ileum of SIV-infected animals contained lower levels of the enzyme myeloperoxidase, which may indicate defects in neutrophil killing capacity. S. Typhimurium was recovered in markedly increased numbers from the mesenteric lymph nodes of SIV-infected macaques, illustrating the increased potential for systemic dissemination during co-infection. Our data suggest that SIV-infection causes a multi-factorial defect in mucosal barrier function that promotes bacterial dissemination.
