Abstract
Recently, we reported stimulation of rat macrophages and human platelets by isolated C5b-9 to synthesize prostaglandin E (PGE) or thromboxane B2 (TXB2). In the present study, we tested whether besides prostanoids, C5b-9 also would induce the production of other mediators. We found that C5b-9 in sublytic concentrations stimulated human granulocytes (polymorphonuclear leukocytes) or monocytes to release oxygen radicals. Furthermore, monocytes release interleukin-1 in response to C5b-9. Thus, besides having a lytic capacity, C5b-9 also functions as a stimulator of various cells.
