520 |a The pro-inflammatory cytokines, TNFα, IL-1 and IL-18, amplify cartilage destruction associated with osteoarthritis (OA). Current data suggest that basic calcium phosphate (BCP) crystals are potent drivers of inflammatory mediator and matrix metalloprotease expression in the OA joint. It has previously been demonstrated that synovial macrophages play a role in initiating and driving BCP-induced inflammation. However, the molecular mechanisms by which BCP crystals exert their effects remain unclear. Here we demonstrate that exposure of macrophages to BCP crystals leads to activation of Syk and PI3 kinase. Furthermore, we show that production of pro-inflammatory cytokines and phosphorylation of the downstream kinase, ERK, are suppressed following treatment with Syk and PI3 kinase inhibitors. Finally, we demonstrate that treatment of macrophages with BCP crystals induces the production of the damage-associated molecule, S100A8, in a Syk dependent manner. We therefore identify Syk and PI3 kinase as potential novel targets for the treatment of BCP-related pathologies
