Figure 4From: CTLA4-Ig interacts with cultured synovial macrophages from rheumatoid arthritis patients and downregulates cytokine productionEvaluation of cytokine production by ELISA assay. Evaluation by ELISA assay of IL-6 and IL-1β production in supernatants of co-cultured macrophage/Jurkat untreated (controls (cnt)) and treated with CTLA4-Ig (10, 100, 500 μg/ml). Results are expressed as mean value ± standard deviation from three experiments. * P < 0.05; ** P < 0.01; *** P < 0.001.Back to article page
