Association of CD19⁺CD24^hiCD27⁺ B cells with disease activity. A The absolute number of CD19⁺CD24^hiCD27⁺ B cells in the blood samples from healthy controls (n = 25), inactive SLE patients (SLEDAI score ≤ 4, n = 14) and active SLE patients (SLEDAI score > 4, n = 27). B Correlation of the proportion of CD19⁺CD24^hiCD27⁺ B cells with the SLEDAI score. C–E Representative cases of a healthy control (C), an inactive SLE patient (D) and an active SLE patient (E). **P < 0.01, ***P < 0.001; ns, not significant
