Immunopharmacology Comments
sPLA2 enzymes catalyze the first step of the arachidonic acid pathway, so are inextricably involved in the production of arachadonic acid for inflammatory mediator synthesis. Excess sPLA2 activity is suggested to contribute to several inflammatory diseases. The sPLA2-1B isozyme has been reported to induce leukotriene B4 (LTB4) production in human neutrophils, using a mechanism independent of arachadonic acid generation [2].
