Abstract

Incubation of patients’ serum catalytically active by type IIA secretory phospholipase A2 (SP-IIA) with serum containing the enzyme in a high concentration but exhibiting no catalytic activity in 1:1 volume ratio led to a significant inhibition of SP-IIA catalytic activity. Donor and patient sera with low levels of SP-IIA had no effect on the serum with SP-IIA activity under these conditions. However, the increase in the content of patients’ serum with a low level of SP-IIA in the incubation mixture to 1:2 (v/v) and of donor serum to 1:3 (v/v) also led to blockade of SP-IIA catalytic activity. These results indicate that human serum contains an SP-IIA inhibitor and its concentration decreases significantly in sera with SP-IIA activity.
