by Gertrud U. Rey Have you ever wondered what would happen if you were infected with two different viruses at the same time? A recent study aimed at addressing this question has produced some astounding new findings. The authors of the study wanted to observe the interactions between respiratory syncytial virus (RSV) and influenza A …

Neuraminidase is one of three different viral proteins embedded in the lipid membrane of influenza virus (NA is blue in the illustration at left). This enzyme has a clear and proven role in virus release from cells. NA is also believed to be important during virus entry, by degrading the mucus barrier of the respiratory …

The hemagglutinin (HA) and neuraminidase (NA) glycoproteins of the influenza virus particle serve distinct functions during infection. The HA binds sialic acid-containing cellular receptors and mediates fusion of the viral and cell membranes, while the NA removes sialic acids from glycoproteins. Apparently this division of labor is not absolute: influenza viruses have been identified with …

The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into cells. I have written about the HA and its …
