In both RA and SLE, we noted significant correlations between the MFI of CD62L in samples incubated without mAbs and that in samples incubated with RTX (r2 = 0.93, 0.91, respectively) and OBZ (r2 = 0.64, 0.71, respectively) (Fig. 5D). This evidence concerns the gene SELL and systemic lupus erythematosus.
