Figure 2.

Correlations 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.
