Live Attenuated Tetravalent Dengue Vaccination in Non-Human Primates

ABSTRACT: We measured genome-wide transcript abundance patterns in 246 whole blood samples collected from 35 cynomolgus macaques before and after vaccination with a live attenuated tetravalent dengue vaccine (TDV) or PBS (placebo). Animal work was conducted at the Charmany Instructional Facility of the School of Veterinary Medicine, University of Wisconsin-Madison, and all animal procedures were approved by the University of Wisconsin-Madison's Animal Care and Use Committee. Thirty-five adult male, DENV-seronegative cynomolgus macaques from Vietnam were placed in quarantine for 30 days prior to the start of the study. Five groups of animals (n=6 animals per group) received TDV either subcutaneously (SC) in 0.5 mL inocula or intradermally (ID) in 0.1 mL inocula using a needle-free injector (PharmaJet' device) or needle and syringe (N&S). Animals received two doses (same route) of TDV either on the same day (Day 0) or sixty days apart. One group (n=5) received PBS by ID route and needle-free injector. On day 90 after primary vaccination, 3 animals from each group were challenged with 105 PFU wt DENV-2 (New Guinea C strain) or 105 PFU wt DENV-4 (Dominica/81 strain) by SC route using N&S. Whole blood samples were collected for transcriptional profiling from all animals on days -11, -2, 1, 3, 5, and 7 before and after immunization, and for placebo animals on days 88, 91, 93, 95, and 97 before and after wt DENV challenge. Blood samples were drawn into PAXgene Blood RNA tubes and stored at -80'C prior to RNA extraction and processing.

Induction of a peptide with activity against a broad spectrum of pathogens in the Aedes aegypti salivary gland, following infection with dengue virus

Project description:Dengue viruses (DENV) are generally maintained in a cycle which requires horizontal transmission via their arthropod vector, Ae. Aegypti, to the vertebrate host. One important consequence of this process is the interference of these arboviruses with both invertebrate and vertebrate immune systems. While infection of vertebrates causes disease, the presence of DENV gives rise to life-long, persistent infection in mosquitoes. The results of a comparative transcriptome analysis between DENV-infected and uninfected salivary glands revealed activation of both the immune deficiency (IMD) and the Toll pathways, as well as involvement of the putative antibacterial cecropin-like peptide (AAEL000598), in controlling DENV infection in Ae. aegypti. The mature form of this peptide was found to be active against DENV and Chikungunya viruses, whereas its precursor also had a strong anti-Leishmania effect. This study is the first to establish a comparative transcriptome analysis of DENV-infected and uninfected salivary glands and demonstrates that certain DENV-induced peptides, that are part of the IMD pathway, possess broad-spectrum anti-pathogenic activity and may have therapeutic potential in human. Infectious blood meals were offered to 3-day-old, adult, female Ae. aegypti Liverpool mosquitoes using a silicone membrane feeder system (Alto et al., 2005). Human blood was combined with DENV-2 16681 to provide a blood meal titer of 5.106 plaque forming units (PFU)/ml. At different time-points after the blood meal, salivary glands were dissected in acid guanidium thiocyanate-phenol-chloroform (RNAble; Eurobio, France) or phosphate-buffered saline (PBS), and the samples were frozen at -70°C until use.

Expression profiling of rat heart and blood after amiodarone treatment

Project description:In the present study, an oligonucleotide microarray platform was used to compare expression profiles of heart and blood in rats treated with amiodarone against respective controls. Male Sprague-Dawley (CD) rats, which were 10 weeks old and weighed 290-320 grams at the beginning of the study, have been treated for ten days with amiodarone by oral route at a dose of 300mg/Kg/die. The study has been constituted by a control group, which received the vehicle (methylcellulose 1%, w/v), and by a treatment group (10 animals for both groups). For each tissue sample, total RNA has been individually extracted and evaluated. For each tissue, three pools/group (2 pools composed of 3 animals and the last one by 4) have been used for microarray analysis. A modulation of 600 genes in heart and 8300 genes in blood has been obtained.

SAGE analysis reveals variation in midgut transcriptomes of dengue-2 susceptible and refractory Aedes aegypti mosquitoes

Project description:Oral susceptibility of Aedes aegypti mosquitoes to dengue viruses varies between different Aedes species and strains. However, the midgut-specific transcriptional profile that may produce this variation is presently obscure and was the subject of our investigation. The variation in active expression between dengue-2 susceptible (SUS) and refractory (REF) mosquitoes was investigated during the first critical 96 hours after infection Transcriptional profiles were mined from respective guts using the serial analysis of gene expression technique (SAGE) and libraries constructed from midguts obtained from mosquitoes that received a dengue-2 infected blood meal (DENV-2), a non infected blood meal (naive) or a 5% sucrose meal (SM). Here we report that variation between DENV-2 infected libraries versus respective naÃ¯ve libraries revealed very few transcripts that were common and statistically significant in DENV-2 infected libraries. In addition, the expression profiles among libraries displayed up regulation of antisense transcripts especially in the SUS strain. A strong proclivity towards strain-specificity in differential expression was observed, which suggested an exclusive transcription that is likely up-regulated after DENV-2 infection Thirty Aedes aegypti female mosquitoes aged 4-5 days were transferred to 500 ml paper cups and offered a 5% sucrose meal (SM), a naÃ¯ve blood meal or a dengue-2 (JAM 1409 strain) infectious blood meal, using standard artificial membrane feeders. Fully engorged females were isolated and maintained on a 5% sucrose solution ad libitum at 26oC and relative humidity till dissection

Early and sustained innate immune response defines pathology and death in nonhuman primates infected by highly pathogenic influenza virus.

Project description:This study revealed important similarities but also critical differences between the H5N1 and 1918-reassortant viruses, highlighting aspects of the host–pathogen interface caused by highly virulent influenza viruses. Animals assigned to 4 experimental groups (n = 8) matched for age, weight, and sex, were inoculated by intratracheal, intranasal, tonsillar, and conjunctival routes with a total of 107 pfu of A/Vietnam/1203/2004 (H5N1) virus, A/Texas/36/91 (H1N1) virus or reassortants of this virus containing either 2 (HA, NA) or 3 (HA, NA, NS) genes from the 1918 virus. Two animals per group were scheduled for sacrifice on days 1, 2, 4, and 7. Two additional animals were used as uninfected control animals and killed on day 7. Oligoarray analyses consisted of comparing array profiles of individual lung samples (with representative pathology and degree of infection) from infected animals to pooled equal masses of mRNA from all lung lobes of 7 reference cynomolgus macaques obtained through the tissue program of the University of Washington National Primate Research Center. There are 2 technical array replicates fro each sample.

Immunologic Control of Zika Virus in Rhesus Monkeys

Project description:Zika virus (ZIKV) is responsible for a major current outbreak in the Americas and has been causally associated with fetal microcephaly as well as Guillain-Barre syndrome in adults. However, the immune responses associated with controlling ZIKV replication remain poorly characterized. Here we report a detailed analysis of innate and adaptive immune responses following ZIKV infection in 16 rhesus monkeys. A robust proinflammatory innate immune response was observed within the first few days of infection, including upregulation of type 1 interferon, which correlated directly with viral loads. Immunomodulatory pathways, including IL-10 and TGF-β, were also upregulated. ZIKV-specific neutralizing antibodies emerged rapidly by day 7 and correlated inversely with viral loads, which were undetectable in peripheral blood by day 6-10. In contrast, virus replication persisted in cerebrospinal fluid (CSF) for at least 21-42 days in 75% (3 of 4) of the monkeys that received the lowest dose of ZIKV tested, and ZIKV-specific antibodies were essentially undetectable in CSF. These data suggest that antibodies play a critical role in the rapid control of acute viremia in the periphery but were largely excluded from the central nervous system, allowing viral persistence at this immuonoprivileged site. 16 outbred, Indian-origin, adult male and female rhesus monkeys (Macaca mulatta) were included in this study. All monkeys were housed at Bioqual, Rockville, MD. Animals were infected with 103-106 pfu (106-109 vp) of our ZIKV-BR or ZIKV-PR challenge stocks by the s.q. route (N=2/group). All animal studies were approved by the appropriate Institutional Animal Care and Use Committee (IACUC).

The identification of putative circulating miRNA biomarkers of Thioacetamide-induced hepatotoxicity.

Project description:The Thioacetamide-treated rat was first identified as a model of hepatotoxicity by Gupta in 1956 and is now well-established, not least because the histopathogical output closely mimics that seen in humans with chronic liver disease. Acute treatment of rats with Thioacetamide causes pronounced necrosis and inflammation. Animals received intraperitoneal (ip) doses of vehicle-only (0.9% (v/v) saline) (n=3), or 100 mg/kg Thioacetamide (n=3) and were sacrificed after 24 hours. Blood was withdrawn via the descending vena cava and immediately transferred into potassium/EDTA tubes. Following centrifugation (16,100g, 4M-BM-0C, 5 min) the plasma was collected and stored at -80M-BM-0C. miRNA microarray profiling of RNA extracted from the plasma of rats treated with Thioacetamide revealed that a subset of miRNAs were differentially expressed following treatment. These miRNAs appeared to mediate pathways involved in hepatic fibrosis and stellate cell activation, suggesting that they might function as predictive biomarkers following compound-induced hepatotoxicity. The changes correlated well with increases in ALT levels, which are the current gold standard method for determining the extent of liver injury. Furthermore, it is hypothesised that particular aetiologies of liver damage might cause differing expression profiles of miRNAs, thus certain miRNAs could be implemented in a panel-type expression study to distinguish between different types of hepatic injury. Single channel miRNA microarrays were performed on n= 3 samples, 2 treatment groups; control and test. Control animals received vehicle-only (0.9% (v/v) saline) via the ip route. Test animals received 100 mg/kg Thioacetamide dissolved in 0.9% (v/v) saline, via the ip route. 24 h after dosing animals were sacrificed using decapitation under terminal anaesthesia.
