[Proteolysis intensification during influenza virus interaction with plasma membrane of sensitive cells]

The possibility of the proteolotic enzymes incorporation into the viral particle and the changes in proteolysis during interaction of the purified influenza virus (A2 Hong-Kong (1)68) with isolated plasmatic membranes of the mice lungs were studied. The presence of trypsin-like protease in the purified influenza virion was found. It is established that proteolysis intensifies during a short-term interaction of the isolated plasmatic membranes with the influenza virus.
