Inhibition of superoxide generation and myeloperoxidase release by carvedilol after receptor and nonreceptor stimulation of human neutrophils.
OBJECTIVES: To compare three stimuli which activate human neutrophils with different signal transduction mechanisms, in order to better localize the effect of the beta-adrenoceptor antagonist carvedilol (CARV) on superoxide generation (O2*-) and myeloperoxidase release (MPO). The effect of CARV [0.1-100 micromol/l] on O2*- generation an.....
