Stratification analysis of the numbers of different types of CD4⁺forkhead box protein 3 (FoxP3)⁺ T cells and the levels of serum interleukin (IL)-10 in seropositive and seronegative anti-ds-DNA systemic lupus erythematosus (SLE) patients. The patients were stratified into seropositive (15 cases) and seronegative (eight cases) anti-dsDNA groups, the numbers of CD4⁺CXCR5⁺FoxP3⁺, CD4⁺CD25⁺FoxP3⁺ and CD4⁺CD25⁻FoxP3⁺ T cells, and the levels of serum IL-10 in these two groups of patients were analysed. The horizontal lines indicate the median values for each group.
