INTRODUCTION: ;Secretory phospholipase A2 (sPLA2) and matrix metalloproteinase (MMP) inhibitors are potent modulators of inflammation with therapeutic potential, but have limited efficacy in rheumatoid arthritis (RA). The objective of this study was to understand the inhibitory mechanism of phospholipase inhibitor from python (PIP)-18 peptide in cultured synovial fibroblasts (SF), and to evaluate its therapeutic potential in a human tumor necrosis factor (hTNF)-driven transgenic mouse (Tg197) model of arthritis.;METHODS: ;Gene and protein expression of sPLA2-IIA, MMP-1, MMP-2, MMP-3, MMP-9, tissue inhibitor of metalloproteinase (TIMP)-1, and TIMP-2 were analyzed by real time PCR and ELISA respectively, in interleukin (IL)-1beta stimulated rheumatoid arthritis (RA) and osteoarthritis (OA) synovial fibroblasts cells treated with or without inhibitors of sPLA2 (PIP-18, LY315920) or MMPs (MMP Inhibitor II). Phosphorylation status of mitogen-activated protein kinase (MAPK) proteins was examined by cell-based ELISA. The effect of PIP-18 was compared with that of celecoxib, methotrexate, infliximab and antiflamin-2 in Tg197 mice after ip administration (thrice weekly for 5 weeks) at two doses (10, 30 mg/kg), and histologic analysis of ankle joints.

3.[Role of secreted and lipoprotein-associated phospholipase A2 in cardiovascular risk].
Ferri N;Corsini A G Ital Cardiol (Rome). 2014 Dec;15(12):664-9. doi: 10.1714/1718.18766.
Phospholipase A(2) (PLA(2)) are enzymes that hydrolyze the ester bond of glycerophospholipids releasing free fatty acids and lysophospholipids, including the arachidonic acid, the precursor of the eicosanoids and the inflammatory cascades. PLA(2) are present in the atherosclerotic plaques and their direct involvement in the proatherogenic inflammatory response is well documented. Epidemiological and genetic studies have demonstrated the correlation of the PLA(2) mass and enzymatic activity with the incidence of cardiovascular diseases. The potential pro-atherogenic role of PLA(2) led to the development of two small molecules, varespladib, a reversible sPLA(2) inhibitor, and darapladib, a selective Lp-PLA(2) inhibitor. Both molecules have demonstrated antiatherosclerotic properties in animal models, and positive effects on atherosclerotic plaque composition evaluated in phase 2 clinical trials. On these grounds, the results of three phase 3 studies have recently been published: the VISTA-16 study with varespladib in patients with acute coronary syndrome, and the STABILITY and SOLID-TIMI 52 studies with darapladib in patients with stable coronary heart disease and acute coronary syndrome, respectively.
