The antibiotic cerulenin, a known inhibitor of fatty acid and sterol synthesis, inhibited bactericidal activity of mouse peritoneal macrophages and chemiluminescence (CL) response upon phagocytosis. The antibiotic also inhibited the CL response of human neutrophils upon exposure to various stimuli such as chemotactic pep tide N-formylmethionylleucylphenylalanine (fMLP), calcium ionophore A23187 and Staphylococcal delta toxin. The loss of CL response of both types of cells was observed only after incubation of the cells with cerulenin for certain periods. The results of radioactive precursor incorporation suggest that lipid metabolism blocked by cerulenin affected in turn signal transduction across the cell membrane and inhibited CL production in these cells.
