Project description:BackgroundGenome-wide profiling to examine brain transcriptional features associated with excessive ethanol (EtOH) consumption has been applied to a variety of species including rodents, nonhuman primates (NHPs), and humans. However, these data were obtained from cross-sectional samples which are particularly vulnerable to individual variation when obtained from small outbred populations typical of human and NHP studies. In the current study, a novel within-subject design was used to examine the effects of voluntary EtOH consumption on prefrontal cortex (PFC) gene expression in a NHP model.MethodsTwo cohorts of cynomolgus macaques (n = 23) underwent a schedule-induced polydipsia procedure to establish EtOH self-administration followed by 6 months of daily open access to EtOH (4% w/v) and water. Individual daily EtOH intakes ranged from an average of 0.7 to 3.7 g/kg/d. Dorsal lateral PFC area 46 (A46) brain biopsies were collected in EtOH-naïve and control monkeys; contralateral A46 biopsies were collected from the same monkeys following the 6 months of fluid consumption. Gene expression changes were assessed using RNA-Seq paired analysis, which allowed for correction of individual baseline differences in gene expression.ResultsA total of 675 genes were significantly down-regulated following EtOH consumption; these were functionally enriched for immune response, cell adhesion, plasma membrane, and extracellular matrix. A total of 567 genes that were up-regulated following EtOH consumption were enriched in microRNA target sites and included target sites associated with Toll-like receptor pathways. The differentially expressed genes were also significantly enriched in transcription factor binding sites.ConclusionsThe data presented here are the first to use a longitudinal biopsy strategy to examine how chronic EtOH consumption affects gene expression in the primate PFC. Prominent effects were seen in both cell adhesion and neuroimmune pathways; the latter contained both pro- and antiinflammatory genes. The data also indicate that changes in miRNAs and transcription factors may be important epigenetic regulators of EtOH consumption.

Project description:Recombinant insect baculoviral vectors efficiently transduce several types of cells in the brain and can possibly be used for gene therapy for brain disorders. To verify the suitability of using these viral vectors to develop gene therapy strategies in the brain, we evaluated immune reactions upon acute administration of baculoviral vectors into the brain of the cynomolgus macaque using microarray global gene expression profiling. Adult male cynomolgus macaques (Macaca fascicularis) were administered with baculovirus BV-HSVtk purified by membrane chromatography + high-speed centrifugation (MC+HS) into the brain.

Project description:The non-human primate (NHP) model (specifically rhesus and cynomolgus macaques) has facilitated our understanding of the pathogenic mechanisms of yellow fever (YF) disease and allowed evaluation of safety and efficacy of YF-17D vaccines. However, the accuracy of this model in mimicking vaccine-induced immunity in humans remains to be fully determined. We used a system biology approach to compare hematological, biochemical, transcriptomic, innate and antibody-mediated immune responses in cynomolgus macaques and human participants following YF-17D vaccination. Immune response progression in cynomolgus macaques followed a similar course as in adult humans, but with slightly earlier onset. Yellow fever virus neutralizing antibody responses occurred earlier in cynomolgus macaques (by Day 7 [D7]), but titers >10 were reached in both species by D14 post-vaccination and were not significantly different by D28 (PRNT50 titers 3.6 Log vs 3.5 Log in cynomolgus macaques and human participants, respectively; p = 0.821). Changes in neutrophils, NK cells, monocytes, T and B cell frequency were higher in cynomolgus macaques and persisted for four weeks versus less than two weeks in humans. Low levels of systemic inflammatory cytokines (IL-1Ra, IL-8, MIP-1α, IP-10, MCP-1 or VEGF) were detected in either or both species, but with no or only slight changes versus baseline. Similar changes in gene expression profiles were elicited in both species. These included enriched and up-regulated type I IFN-associated viral sensing, antiviral innate response, and dendritic cell activation pathways D3–D7 post-vaccination in both species. Hematological and blood biochemical parameters remained relatively unchanged versus baseline in both species. Low level YF-17D viremia (RNAemia) was transiently detected in some cynomolgus macaques (28% [5/18]) but generally absent in humans (except one participant [5%; 1/20]). Importance: Cynomolgus macaques were confirmed as a valid surrogate model for replicating YF-17D vaccine-induced responses in humans, and suggest a key role for type I IFN.

Project description:In this study, we established the COVID-19 infection model in cynomolgus macaques (CMs), the differentially expressed proteins was analyzed in lung tissue collected from 3 untreated (NC1-3) and 4 CMs inoculated with SARS-CoV-2 for 7 days (nCoV1-4). The results showed the differentially expressed genes (DEGs) before and after exposure. The median CV values was analyzed to confirm the proteomics data with good degree of consistency and reproducibility (median<0.25). The histogram of GO terms enriched in biological process, cellular component and molecular function.

Project description:Smallpox has played an unparalleled role in human history and remains a significant potential threat to public health. Despite the historical significance of this disease, we know little about the underlying pathophysiology or the virulence mechanisms of the causative agent, variola virus. To improve our understanding of variola pathogenesis and variola-host interactions, we examined the molecular and cellular features of hemorrhagic smallpox in cynomolgus macaques. We used cDNA microarrays to analyze host gene expression patterns in sequential blood samples from each of 22 infected animals. Variola infection elicited striking and temporally coordinated patterns of gene expression in peripheral blood. Of particular interest were features that appear to represent an IFN response, cell proliferation, immunoglobulin gene expression, viral dose-dependent gene expression patterns, and viral modulation of the host immune response. The virtual absence of a tumor necrosis factor /NF-B-activated transcriptional program in the face of an overwhelming systemic infection suggests that variola gene products may ablate this response. These results provide a detailed picture of the host transcriptional response during smallpox infection, and may help guide the development of diagnostic, therapeutic, and prophylactic strategies.
