A study published in PLOS PATHOGENS describes the prevalence and functions of mutations in neuraminidase enzyme of avian H5N1 influenza viruses that are preferentially selected in human H5N1 influenza ...

To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical ...

A schematic diagram of the influenza virus, showing the surface proteins hemagglutinin (blue, peanut shaped) and neuraminidase (red, flower shaped), to which antibodies attach during an immune ...

Troy, N.Y. — What happens if the next big influenza mutation proves resistant to the available anti-viral drugs? This question is presenting itself right now to scientists and health officials this ...

DURHAM, N.C. -- Duke researchers have opened a new avenue in the attack against influenza viruses by creating a vaccine that encourages the immune system to target a portion of the virus surface that ...

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses. The devastating respiratory virus, influenza A virus, utilize its hemagglutinin ...

Vaccines now in clinical trials can raise broad-spectrum antibodies against more than one form of hemagglutinin and provide protection against the flu strains that have been most troublesome from a ...

The difference between seasonal flu and pandemic flu is whether or not people have had a chance to build immunity to the virus through previous exposure. People are exposed to influenza viruses ...

A new analysis from the Paul Ehrlich Institute (PEI) and University Medical Center Freiburg, Freiburg, Germany, showed that only certain influenza A virus (IAV) strains trigger life-threatening ...

An experimental influenza vaccine carrying more than 80,000 variations of hemagglutinin antigens caused the immune system of mice and ferrets to respond more strongly to less variable portions of the ...
