Effects of CKD-L on cell viability in PBMC from RA patients (n = 6). PBMC from RA patients were cultured in a 96-well plate for 24 h in the presence of lipopolysaccharide (LPS; 100 ng/ml) and HDAC inhibitors at different concentrations (0.01 to 5 μM). Cell viability was determined using the MTT assay. Bars represent means and SDs. All experiments were carried out in triplicate. *p < 0.001, vs LPS
