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:HIV-infected persons are at increased risk for developing pulmonary diseases including chronic obstructive pulmonary disease (COPD), and the fungal opportunistic pathogen, Pneumocystis jirovecii (Pc) has been implicated in the pathogenesis of HIV-related COPD. We previously developed a non-human primate model of HIV-related COPD using simian-human immunodeficiency virus (SHIV) and Pc co-infection in cynomolgus macaques. In the present study we examined gene expression profiles in lung tissue from SHIV/Pc co-infected monkeys with COPD and compared them to SHIV-infected monkeys infected with normal lung function. Microarray technology was used to develop gene profiles, and differential gene expression was determined by a comparative evaluation of competing normalization methods applied to our expression data set followed by validation using quantitative real-time polymerase chain reaction analysis for select genes. Of over 52,000 transcripts representing more than 20,000 genes analyzed, the SHIV/Pc infected macaques with COPD exhibited 243 differentially expressed (DE) genes compared to SHIV-infected monkeys with normal lung function. DE genes fell into a number of functional categories which may be important in COPD development including: inflammation (pulmonary surfactants A2, B, C, D, upregulated; alternative macrophage activation-associated CC chemokine, upregulated), protease/antiprotease balance (cathepsin H, upregulated; alpha-1-chymotrypsin and secretory leukocyte peptidase inhibitor, downregulated), redox balance (glutathione peroxidase 4 and mitochondrial aldehyde dehydrogenase 2, upregulated) and tissue homeostasis (connective tissue growth factor, downregulated; ornithine decarboxylase antizyme, upregulated). These results identify factors and pathways that may be involved in early development of Pneumocystis and SHIV-associated COPD and reveal several novel, potential therapeutic targets. There are totally 11 samples in the experiment. The sample breakdown is as follows: KN14(group 1) is a true control in that the monkey was not infected with simian-human immunodeficiency virus (SHIV) nor was it colonized with Pneumocystis. KN02, KN03, KN07 and KN08 (group 2) are also controls of a sort. They were infected with SHIV but they did not become colonized with Pneumocystis. The remainder (KN01, KN04, KN06, KN11, KN12, KN13) (group3) were both infected with SHIV and colonized with Pneumocystis. The primary interest is in comparing the two SHIV-infected groups (2 and 3)

Project description:Impact of CD8 depletion on peripheral CD4+ T cells transcriptome during ART-treated SIV infection of rhesus macaques. Analysis of CD8+ T cells, CD4+ T cells, and NK cell transcriptomes following administration of HIV/SIV latency reversing agent IL-15 superagonist N-803 in ART-suppressed SIV infected rhesus macaques. Methods: RNA-Seq of sorted CD4+ T cells from SIV-infected, ART-suppressed rhesus macaques before intervention with the anti-CD8a depleting antibody MT807R1 and then again on day 3, week 2, and week 4 following the start of intervention. Some animals also had an intervention that includes four weekly administrations of the IL-15 superagonist complex N-803 initiated at the time of CD8 depletion. Methods: RNA-Seq of sorted CD4+ T cells, CD8+ T cells, and NK cells from SIV-infected, ART-suppressed rhesus macaques before intervention with four weekly administrations of the IL-15 superagonist complex N-803, then again on day 3, week 2, and week 4 following the start of intervention. Methods: RNA from sorted cells was collected and extracted and DNA was digested. Libraries were prepared and normalized, pooled, and clustered on a flow cells for sequencing. RNAseq data were aligned to the MacaM v7.8 assembly of the Indian rhesus macaque genome. To identify pathways differentially modulated, Gene Set Enrichment Analysis (GSEA)34 was performed on the ranked transcript lists using 1000 phenotype permutations and random seeding. Gene sets used included the MSigDB H (hallmark) gene sets

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:Question Addressed: Does gene expression change in the buccal mucosa of Lymphocryptovirus (LCV) infected animals when they are chronically infected with Simian immunodeficiency virus (SIV)? Oropharyngeal mucosal tissue samples were collected from rhesus macaques. A pooled common reference was used for all hybridizations. This reference was composed of RNA harvested from rhesus macaques not infected with either LCV or SIV. Infection: Animals were infected with SIV and/or LCV

Project description:To gain insights into the early immune dynamics of transcriptional changes during SARS-CoV-2 infection in airways, we performed longitudinal scRNA-Seq of the broncho-alveolar lavage (BAL) cells isolated from SARS-CoV-2 infected rhesus macaques. We found early induction of innate type-1 interferon responses with accumulation of a distinct macrophage population that possesses an interferon-driven innate anti-viral gene signature early during infection.
