[HTML][HTML] A bifunctional role for group IIA secreted phospholipase A2 in human rheumatoid fibroblast-like synoviocyte arachidonic acid metabolism

Human group IIA-secreted phospholipase A 2 (sPLA 2-IIA) is an important regulator of
cytokine-mediated inflammatory responses in both in vitro and in vivo models of rheumatoid
arthritis (RA). However, treatment of RA patients with sPLA 2-IIA inhibitors shows only
transient benefit. Using an activity-impaired sPLA 2-IIA mutant protein (H48Q), we show that
up-regulation of TNF-dependent PGE 2 production and cyclooxygenase-2 (COX-2)
induction by exogenous sPLA 2-IIA in RA fibroblast-like synoviocytes (FLSs) is independent …
