PRDM1 levels are enhanced in memory B cells following IL-21 stimulation. (A) SOCS1 (left) and SOCS3 (right) mRNA expression in CD20+ and total memory B cells from (black circles) Control (n = 7), (gray triangles) RA (n = 14) subjects as assessed by mRNA flow cytometry. (B) miR155 levels in total and memory B cells (black circles) Control (n = 7), (gray triangles) RA (n = 14) subjects collected with miRNA flow cytometry. (C) PRDM1 mRNA levels in memory B cells from control (circles, n = 5) and RA subjects (triangles, n = 10) at baseline (filled) and 48 h (unfilled) after stimulation with IL-21 (50 ng/mL) and measured by mRNA flow cytometry (n = 15). Significance was determined using Mann Whitney U tests.
