background preventing the seasonal or pandemic outbreak of influenza can be powerful and cost-effective. objectives in this study, we constructed a novel virus-like particle (vlp) platform that contains two hemagglutinin (ha) subtypes and evaluated immunogenicity of constructed vlp in mice. materials and methods this recombinant candidate vaccine model resulted in the expression of two has of h...

Pseudotype viruses: applications and troubleshooting’ (EuroSciCon 2013), a 1-day conference held at Cineworld: The O2 (London, UK) on 2 October 2013, focused on the technique of pseudotyping enveloped viruses (for a review of the technique, see [1]). The talks and posters covered the challenges and successes of pseudotyping viruses from a broad range of families (Retroviridae, Flaviviridae, Ort...

Equine influenza virus belongs to the family Orthomyxoviridae (enveloped RNA viruses having helicoidal symmetry). Until 1963 equine influenza was attributed to a single type of virus, isolated and identified in Prague in 1956, and now referred to as inf luenza/A/equine/Prague/1/56 (H7N7). A strain of virus completely different in its antigenic properties appeared in 1963 in the USA. This subtyp...

Influenza A virus belongs to the family of Orthomyxoviridae. It is an enveloped virus with a negative sense RNA segmented genome that encodes for 11 viral genes. This virus has evolved a number of mechanisms that enable it to invade host cells and subvert the host cell machinery for its own purpose, that is, for the sole production of more virus. Two of the mechanisms that the virus uses are "c...

Cholesteryl 3",4"-dimethoxycinnamate (7) and a new synthesized o-coumaroyl ester of 3 beta-(2'-hydroxyethoxy)-cholest-5-en (13) exhibited a marked activity against poliovirus type 1 (Mahoney). Compound 7 showed an approximately 20-fold greater selectivity in its antiviral activity than compound 13. These compounds were selected from thirteen steryl esters of cinnamic acid derivatives through an...

Etiology • Influenza virus C (IVC) and influenza virus D (IVD) are enveloped RNA viruses in the family Orthomyxoviridae. They are more closely related to each other than to influenza virus A (IVA) or influenza virus B (IVB), containing seven genomic segments and a hemagglutinin-esterase (HE) fusion protein responsible for recognition, binding, and destruction of host receptors. • IVC appears to...

Influenza viruses are members of the Orthomyxoviridae family, of which influenza A, B, and C viruses constitute three separate genera. Arterial thrombosis associated with H1N1 influenza A virus infection has rarely been reported. A Turkish man aged 28 years was admitted to our emergency department with dyspnea, bilateral lower extremity insensitivity, and cold. He reported symptoms of fever, my...

The ectodomain of the Ebola virus Gp2 glycoprotein was solubilized with a trimeric, isoleucine zipper derived from GCN4 (pIIGCN4) in place of the hydrophobic fusion peptide at the N terminus. This chimeric molecule forms a trimeric, highly alpha-helical, and very thermostable molecule, as determined by chemical crosslinking and circular dichroism. Electron microscopy indicates that Gp2 folds in...
