title: Lack of association between the elevation of adenosine 3',5'-cyclic monophosphate and the potentiation of the interferon-induced antiviral state by noradrenaline in normal and tumoral rat cells.
abstract: Rat interferon (IF) induced a moderate and persistent elevation of adenosine 3',5'-cyclic monophosphate (cAMP) after 6 h of contact with rat embryo fibroblasts (REFs), whereas in rat glial tumoral c6 cells IF did not enhance cAMP. Noradrenaline potentiated the antiviral state of REFs treated for 2 h or more with IF and increased cAMP in these cells, but it did not potentiate the IF-induced antiviral state of C6 cells. However, as the control cells, IF-treated C6 cells responded to catecholamines by a 100-fold or more increase in cAMP. This suggested that cAMP was not primarily involved in the establishment of the antiviral state.
