Project description:Influenza A viruses (IAVs) present major public health threats from annual seasonal epidemics and pandemics as well as from viruses adapted to a variety of animals including poultry, pigs, and horses. Vaccines that broadly protect against all such IAVs, so-called “universal” influenza vaccines, do not currently exist, but are urgently needed. Here, we demonstrated that an inactivated, multivalent whole virus vaccine, delivered intramuscularly or intranasally, was broadly protective against challenges with multiple IAV hemagglutinin and neuraminidase subtypes in both mice and ferrets. The vaccine is comprised of four beta-propiolactone-inactivated low pathogenicity avian influenza A virus subtypes of H1N9, H3N8, H5N1, or H7N3. Vaccinated mice and ferrets demonstrated substantial protection against a variety of IAVs, including the 1918 H1N1 strain, the highly pathogenic avian H5N8 strain, and H7N9. We also observed protection against challenge with antigenically variable and heterosubtypic avian, swine, and human viruses. Compared to mock vaccinated animals, vaccinated mice and ferrets demonstrated marked reductions in viral titers, lung pathology, and host inflammatory responses. This vaccine approach indicates the feasibility of eliciting broad, heterosubtypic IAV protection and identifies a promising candidate for influenza vaccine clinical development.

Project description:The goal of this study is to use newly designed ferret Agilent arrays to compare transcriptome profiles between wild type, CF3959(-/-) and CF3959(+/-) ferrets. Lung and trachea tissues from newborn and 15 day-old ferrets were RNA-extracted and subsequently analyzed by microarray. Using the newly designed ferret Agilent arrays, we compared the transcriptome profiles between wild type, CF3959(-/-) and CF3959(+/-) ferrets. Samples sets: RNA from a combination of trachea and lung tissue from 4 newborn wild type ferrets and 4 newborn CF3959(-/-) ferrets. In addition, lung tissue from two 15 day-old wild type, three 15 day-old CF3959(+/-) and three 15 day-old CF3959(-/-) ferrets was RNA-extracted and subsequently analyzed by microarray.

Project description:The infected ferrets depleted of alveolar macrophages showed up-regulation of inflammatory related genes compared to the infected ferrets which has alveolar macrophage. There are three group of ferret. One is the infected ferrets depleted of alveolar macrophages. Another is the infected ferret non-depleted of alveolar macrophages. The other is mock

Project description:To further investigate the underlying mechanisms of severe acute respiratory syndrome (SARS) pathogenesis and evaluate the therapeutic efficacy of potential drugs and vaccines it is necessary to use an animal model that is highly representative of the human condition in terms of respiratory anatomy, physiology and clinical sequelae. The ferret, Mustela putorius furo, supports SARS-CoV replication and displays many of the symptoms and pathological features seen in SARS-CoV-infected humans. We have recently established a SARS-CoV infection-challenge ferret platform for use in evaluating potential therapeutics to treat SARS. The main objective of the current study was to extend our previous results and identify early host immune responses upon infection and determine immune correlates of protection upon challenge with SARS-CoV in ferrets. Keywords: time course This study is a simple time course (58 day) examination of host responses in 35 SARS-CoV (TOR2) infected ferrets with the addition of a challenge inoculation of SARS CoV (TOR2) at day 29 post infection. Three mock-infected ferrets are included as negative controls. Due to the unavailability of ferret microarrays, Affymetrix Canine 2.0 oligonucleotide arrays were chosen following sequence analysis of our ferret cDNA library (~5000 clones) and demonstration of high levels of homology (>80%) between dog and ferret.

Project description:The domestic ferret has recently been described as a uniformly lethal model of infection for three species of Ebolavirus known to be pathogenic to humans. Reagents to systematically analyze the ferret host response to infection are lacking; however, the recent publication of a draft ferret genome has opened the potential for transcriptional analysis of ferret models of disease. In this work, we present comparative analysis of longitudinally sampled blood taken from ferrets and non-human primates infected with lethal doses of the Makona strain of Zaire ebolavirus. Strong induction of proinflammatory and prothrombotic signaling programs were present in both ferrets and non-human primates and both transcriptomes were similar to previously published datasets of fatal cases of human Ebola virus infection.

Project description:Severe fever with thrombocytopenia syndrome phlebovirus (SFTSV), listed in the WHO most dangerous pathogens, has 12-30% fatality rates with a characteristic thrombocytopenia syndrome. With a majority of clinically diagnosed SFTSV patients older than ~50 years, age is a critical risk factor for SFTSV morbidity and mortality. Here, we report an age-dependent ferret model of SFTSV infection and pathogenesis that fully recapitulates the clinical manifestations of human infections. While young adult ferrets (≤2 years old) did not show any clinical symptoms and mortality, SFTSV-infected aged ferrets (≥4 years old) demonstrated severe thrombocytopenia, reduced white blood cells, and high fever with 93% mortality rate. Moreover, significantly higher viral load was observed in aged ferrets. Transcriptome analysis of SFTSV-infected young ferrets revealed strong interferon-mediated anti-viral signaling, whereas inflammatory immune responses were markedly upregulated and persisted in aged ferrets. Thus, this immunocompetent age-dependent ferret model should be useful for anti-SFTSV therapy and vaccine development.
