Figure 8From: Initiation but no execution - modulation of peripheral blood lymphocyte apoptosis in rheumatoid arthritis - a potential role for heat shock protein 70Detection of HSP70 in peripheral lymphocytes. A: Mean fluorescence intensity histogram for intra-cellular detection of HSP70 by flow cytometry. B: Proportion of PBL with detectable levels of HSP70 was higher in RA patients (* p = 0.0001; Mann-Whitney test). C: Representative western blot analysis of HSP70 in total PBL protein. D: HSP70 levels significantly elevated in RA patients (* p = 0.0090; unpaired t-test).Back to article page
