title: [Effect of interferon on the cAMP system in cells].
abstract: The increase in cAMP concentration in CaOv cells affected by alpha-interferon has been found to have a two wave character with the maximums at 4 and 24 h after the effect. The waves are due to the increase in adenylate cyclase activity and to the decrease in the activity of cAMP phosphodiesterase. The described changes were characteristic of the native and partially purified interferon and depended on the concentration of interferon used (optimal effect at 1200 IU/ml-1). It suffices to notice that the described effects were more largely expressed when the preparations of the native alpha-interferon were used. The correlation was noticed between the increase in adenylate cyclase activity, the decrease in cAMP phosphodiesterase and the concentration of the cyclic nucleotide as well as the expression of antiproliferative effect. The correlation was less significant for antiviral effect.
