Baculoviral Expression of Influenza A Virus (H1N1 New Caledonia) Neuraminidase in Insect Cells

Background and Aims: Each year, the influenza virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, an influenza vaccine that ensures protection with only a single dose would be a much more cost effective approach to influenza prophylaxis. Generation of Influenza non-replicating virus-like particles (VLP) in baculoviral expression system is an attr...

2009 H1N1 Influenza Virus Seroepidemiology

Development and Sequence Analysis of a Cold-Adapted Strain of Influenza A/New Caledonia/20/1999(H1N1) Virus

Background and Aims: Vaccination is the most effective method to prevent influenza infection. Among the available vaccines, cold-adapted live-virus vaccines are suitable approach that have been produced and evaluated for recent years in few countries. The goal of this project was to derivate a cold adapted variant of the influenza A/New Caledonia/20/1999(H1N1). Materials and Methods: Influenza ...

Design, Production, and Evaluation of Virosomes from H1N1 Influenza Virus

Background: The last two decades witnessed the spread of the first generation of influenza viruses. Influenza virosomes are promising tools in vaccine and immunotherapy programs because of their applications in various medical fields. The aim of the present study was to construct cationic virosomes derived from influenza virus using dialyzable detergent (DCPC) and cationic lipid (DOTAP) in vit...

Construction of Influenza A/H1N1 Virosomal Nanobioparticles

Background and Aims: Influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. Vaccination is one of the best ways to prevent infections including influenza. Influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (RNP). A vi...

Clinical Aspects of Pandemic 2009 Influenza A (H1N1) Virus Infection

Copyright © 2010 Massachusetts Medical Society. During the spring of 2009, a novel influenza A (H1N1) virus of swine origin caused human infection and acute respiratory illness in Mexico.1,2 After initially spreading among persons in the United States and Canada,3,4 the virus spread globally, resulting in the first influenza pandemic since 1968 with circulation outside the usual influenza seaso...
