Figure 4From: Targeting IL-6 by both passive or active immunization strategies prevents bleomycin-induced skin fibrosisAnti-mIL-6 autoantibody production in the group of mice immunized against mIS200 peptide and in the groups of mice immunized against keyhole limpet hemocyanin (KLH) alone. No anti-IL-6 autoantibodies were detected in serum samples from mice immunized against KLH alone compared with the mice immunized against mIS200 peptide. Bars represent mean ± standard deviation.Back to article page
