(Submitter supplied) Recent studies of nonhuman primates (NHPs) have suggested that during the acute phase of infection, antiviral mucosal immunity is restricting viral replication in the primary infection compartment. These studies imply that HIV achieves systemic infection as a consequence of a failure in host antiviral immunity. Here, we used high-dose intrarectal inoculation of rhesus macaques with SIVmac251 to examine how the mucosal immune system is overcome by SIV during acute infection. more...

(Submitter supplied) This study describes differential miRNA expression in small intestinal lamina propria leukocyte samples longitudinally during the course of SIV infection of rhesus macaques. Notably, the T-cell activation associated miR-15b, miR-142-3p, miR-142-5p and miR-150 expression was significantly downregulated at 90 and 180DPI. Further, reporter and overexpression assays validated IRAK1 as a direct miR-150 target. more...

(Submitter supplied) Pathogenic HIV/SIV infection of humans and rhesus macaques (RMs) induces persistently high production of type-I interferon (IFN-I) which is thought to contribute to disease progression. To elucidate the specific role of IFN in SIV pathogenesis, 12 RMs were treated prior to i.v. SIVmac239 infection with a high or a low dose of an antibody (AGS-009) that neutralizes most IFN subtypes, and compared with six mock-infused, SIV-infected controls. more...

(Submitter supplied) The mucosa that lines the respiratory and gastrointestinal (GI) tracts is an important portal of entry for pathogens and provides the frontline of immune defense against HIV infection. Using the simian immunodeficiency virus (SIV) rhesus macaque model, we have performed a comparative analysis of host gene expression in the lung and GI mucosa in response to SIV infection and antiretroviral therapy. Microarrays were used to characterize changes in gene expression in the colonic, jejunal, and pulmonary (lung) mucosa that occur during chronic SIV infection in the presence or absence of antiretroviral therapy.

(Submitter supplied) The study describes miRNA expression in colon tissue following delta 9 tetrahydrocannabinol (Δ9-THC) administration to chronically SIV-infected rhesus macaques. To identify the underlying molecular mechanisms underlying its anti-inflammatory effects, we simultaneously profiled miRNA and mRNA expression in colon of chronically simian immunodeficiency virus (SIV)-infected rhesus macaques (RMs) administered either vehicle (VEH/SIV; n=9) or Δ9- tetrahydrocannabinol (THC; THC/SIV; n=8). more...

(Submitter supplied) We profiled and characterized mRNA expression in colon of 12 chronically SIV-infected rhesus macaques (RMs) receiving vehicle (n=7) or delta-9-tetrahydrocannabinol (THC) and 4 uninfected control macaques. Further analysis identified significant downregulation of genes associated with ion transport, epithelial barrier integrity/function, protection against oxidative injury, double stranded DNA damage repair and autophagy. more...

(Submitter supplied) This study describes differential miRNA expression in intact colon tissue during acute SIV infection of rhesus macaques. Nine miRNAs were found to be significantly affected by infection, with 5 down-regulated and 4 up-regulated miRNAs. The expression of one upregulated miRNA was further characterized and found to be significantly elevated specifically in response to SIV replication and not immune activation/inflammation accompanying SIV infection.

(Submitter supplied) The study describes miRNA expression in intact duodenum following chronic delta 9 tetrahydrocannabinol (Δ9-THC) administration to SIV-infected rhesus macaques. Chronic Δ9-THC administration to uninfected macaques significantly and positively modulated intestinal miRNA expression by increasing the total number of differentially expressed miRNAs from 14 to 60 days post infection (DPI). At 60DPI, ~28% of miRNAs showed decreased expression in VEH/SIV compared to none in the THC/SIV group. more...
