Abstract

Synthetic lipopeptides activate superoxide-anion (O2-) formation in human neutrophils in a pertussis-toxin (PTX)-sensitive manner, suggesting the involvement of G-proteins of the Gi family in the signal-transduction pathway. We compared G-protein activation by lipopeptides and the chemotactic peptide N-formylmethionyl-leucyl-phenylalanine (fMLP) in dibutyryl-cyclic-AMP-differentiated HL-60 cells. ...
