stimulators were n-formyl-methionyl-leucyl-phenylalanine ( fmlp , affecting cells via specific membrane receptors ) and phorbol-myristate-acetate ( pma , activating protein kinase c , thereby short-cutting intramembraneous steps in normal signal transmission , and presumably provoking near-maximal cell responses with the dose applied ) .
