Interaction of plasma membranes with influenza virus. VI. The possible role of the adenylate cyclase system
Abstract
The amounts of released soluble (s) antigen of influenza A/WSN virus were increased when the virus was allowed to interact with isolated plasma membranes in a medium containing substances enhancing the level of adenosine 3',5' cyclic monophosphate (c'AMP) or activating the enzyme adenylate cyclase. By contrast, less s-antigen was released upon addition to the incubation medium of foetal calf serum or calf serum proteins which activate c'AMP phosphodiesterase and thus decrease the level of c'AMP. Changes in the amount of released s-antigen were parallelled by changes in the activities of membrane Ca-adenosine triphosphatase and creatine phosphokinase.
