Figure 4From: B lymphocyte stimulator (BLyS) isoforms in systemic lupus erythematosus: disease activity correlates better with blood leukocyte BLyS mRNA levels than with plasma BLyS protein levelsCorrelations in SLE patients between changes in SLEDAI and BLyS parameters. Individual (a,d) BLyS protein levels, (b,e) full-length BLyS mRNA levels, and (c,f) ΔBLyS mRNA levels are plotted according to directional changes in SLEDAI scores (a–c) or modified SLEDAI scores (d–f) between the first and second clinical assessments. BLyS, B lymphocyte stimulator; SLEDAI, Systemic Lupus Erythematosus Disease Activity Index.Back to article page
