pubmed:abstractText |
Fluoride elicited in liver macrophages a release of arachidonic acid and prostaglandins but not formation of inositol phosphates or superoxide. The effects of fluoride required extracellular calcium and were inhibited by staurosporine and by phorbol ester treatment of the cells. Furthermore, fluoride led to a translocation of protein kinase C from the cytosol to membranes. This indicates that the calcium-dependent protein kinase C is involved in the action of fluoride. Cholera toxin decreased the zymosan-induced release of arachidonic acid and prostaglandins but not of inositol phosphates or superoxide. Pertussis toxin ADP-ribosylated a 41,000 molecular weight membrane protein; enhanced specifically the zymosan-induced formation of prostaglandin(PG)E2 but did not affect the zymosan-induced release of arachidonic acid, PGD2, inositol phosphates or superoxide. These data suggest that activation of phospholipase (PL)A2, phosphoinositide (PI)-specific PLC and NADPH oxidase in liver macrophages is most probably not mediated by activation of guanine nucleotide binding (G)-proteins coupled directly to these enzymes.
