Fig. 4From: The synthetic cannabinoid WIN55,212-2 mesylate decreases the production of inflammatory mediators in rheumatoid arthritis synovial fibroblasts by activating CB2, TRPV1, TRPA1 and yet unidentified receptor targetsImpact of fetal calf serum (FCS) content on the effects of high concentrations of WIN55212-2 mesylate (WIN, 10−6M to 10−5M)) on TNF-induced IL-6 (a), IL-8 (b) and MMP-3 (c) production in RA and OA synovial fibroblasts. Cytokine/MMP-3 production was determined under hypoxic (1 % O2) conditions. ***p < 0.001, **p < 0.01, *p < 0.05 for comparisons vs WIN/TNF with 0 % FCS. The general linear model with Bonferroni correction was used for all comparisons. All data are given as mean ± semBack to article page
