Figure 6.
Relation between serum APRIL levels and serum anti-dsDNA titres. (A, B) Serum APRIL levels (filled circles) and serum anti-dsDNA titres (open squares) were determined in two representative patients with SLE in whom changes in serum APRIL levels largely paralleled those in serum anti-dsDNA titres. (C, D) Serum APRIL levels and serum anti-dsDNA titres were determined in two representative patients with SLE in whom changes in serum APRIL levels were largely anti-parallel to those in serum anti-dsDNA titres. (E) Serum anti-dsDNA titres plotted against serum APRIL levels for the 275 individual serum samples obtained from the 34 anti-dsDNA positive patients with SLE.
