Abstract
The level of 2-5A synthetase in extracts of peripheral blood lymphocytes and a specific protein kinase activity in platelet-rich plasma were measured in normal individuals and in patients suffering from viral or bacterial infections. The level of these enzymes was tested at different times during the disease. The level of 2-5A synthetase and the protein kinase activity was enhanced by several-fold during viral and bacterial infections and decreased during the course of the disease in parallel with clinical ameliorations and reversal of clinical symptoms. Among the different types of infections studied, higher levels of these enzymes were observed during viral than bacterial infections. Our results emphasize the use of these enzymes as markers to evaluate the state of the disease and recovery. Furthermore, they provide evidence for the production of interferon during different types of infection.
