TNFα protein production by unstimulated peripheral blood mononuclear cells from DLE, SCLE, tumid TLE and DM patients and from controls. TLE should be written in the figure Peripheral blood mononuclear cells (PBMCs) were cultured for 24 hours, followed by collection of supernatants. The concentration of TNFα in the supernatants was measured by ELISA. Bars show the means and SD. ***P < 0.001 vs control PBMCs by Dunnett's multiple comparison test. DLE = discoid lupus erythematosus, DM = dermatomyositis, TLE, tumid lupus erythematosus, SCLE, subacute cutaneous lupus erythematosus.
