Abstract | PURPOSE: METHODS: Treg were identified by using CD4+CD25+high and CD4+CD25+CD127dim staining approaches in SLE and RA patients and healthy controls. Association of both identified Treg levels with various serum markers and clinical presentation was also examined. RESULTS: Blood CD4+CD25+CD127dim cells levels were 11.4+3.57 %, 9.76+2.37 % and 6.95+1.16 %; while CD4+CD25+high cells were 1.46+1.09 %, 0.95+0.59 % and 1.87+1.14 % in SLE patients, RA patients and healthy controls respectively. Number of CD4+CD25+CD127dim cells was higher than CD4+CD25+high cells in blood samples of all three study groups. Levels of CD4+CD25+CD127dim cells were significantly higher in SLE and RA patients, compared to healthy controls, but this difference was not observed for CD4+CD25+high Treg. CD4+CD25+high levels showed significant correlation with serum C4, IFN-γ and IL-10 levels in healthy subjects and with C4 levels and fever in SLE patients. CD4+CD25+CD127dim levels showed significant association with alopecia and oral ulcers in SLE patients only, but no correlation with measured serum markers. CONCLUSION: Results suggest that both staining approaches detect Treg differently and also that Treg play different role in pathogenesis of SLE and RA.
