Figure 2. Arthritis-susceptible MHCII dependent anti-mC5a IgG induction.
(A–C) Collagen induced arthritis susceptible mouse strains expressing the human MHCII DR4 allele (hDR4, A) or murine H-2r (B) and H-2q (C) haplotypes were injected with the different C5a-4NPA variants (3 mice/group). Sera at d14 were screened for an IgG response crossreacting with murine wtC5a. Data show means with SD.
