2) could elicit leukotriene B 4 (LTB 4) biosynthesis in human neutrophils (Han, SK, Kim, KP,
Koduri, R., Bittova, L., Munoz, NM, Leff, AR, Wilton, DC, Gelb, MH, and Cho, W.(1999) J. Biol.
Chem. 274, 11881–11888). To determine the mechanism of the hVPLA 2-induced LTB 4
biosynthesis in neutrophils, we thoroughly examined the effects of hVPLA 2 and their lipid
products on the activity of group IVA cytosolic PLA 2 (cPLA 2) and LTB 4 biosynthesis under …
