Formyl peptides and ATP stimulate Ca2+ and Na+ inward currents through non-selective cation channels via G-proteins in dibutyryl cyclic AMP-differentiated HL-60 cells. Involvement of Ca2+ and Na+ in the activation of beta-glucuronidase release and superoxide production.

Abstract

In human neutrophils, the chemotactic peptide N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP) induces increases in the intracellular free Ca2+ concentration ([Ca2+]i) with subsequent activation of beta-glucuronidase release and superoxide (O2-) production. Results from several laboratories suggest that the increase in [Ca2+]i is due to activation of non-selective cation (NSC) channels. We ...
