title: Role of the 15-lipoxygenase in the immune system.
abstract: Recent data from our laboratory, as well as supporting evidence from other investigators, strongly suggest that the PMN 15-LO exists in a cryptic state. Several stimuli, including HETEs, can convert the inactive 15-LO to an active species that can metabolize AA to a variety of products. Many of these metabolites have been reported to modulate various components of the immune response.
