Endogenous nitric oxide activates prostaglandin F2 alpha production in human microglial cells but not in astrocytes: a study of interactions between eicosanoids, nitric oxide, and superoxide anion (O2-) regulatory pathways.


Secretion of the eicosanoids, nitric oxide (NO.) and superoxide anion (O2.-) was evaluated in human embryonic astrocytes and microglia. An inducible form of cyclo-oxygenase (COX 2) was demonstrated in astrocytes and microglia after IL-1 beta plus IFN-gamma stimulation; since 1) large amounts of PGF2 alpha were released; 2) PGF2 alpha secretion required… (More)
