Figure 2From: 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 the SLE patients between BLyS parameters and plasma immunoglobulin levels. Individual (a,d,g,j) BLyS protein levels, (b,e,h,k) full-length BLyS mRNA levels, and (c,f,i,l) ΔBLyS mRNA levels are plotted against corresponding plasma total immunoglobulin levels (a–c), IgG levels (d–f), IgA levels (g–i), and IgM levels (j–l). BLyS, B lymphocyte stimulator; IL, interleukin.Back to article page
