The earliest pathological changes of arthritis in gp130F759 develop at 5 months of age. (A) Sera were collected from WT (n=5) and gp130F759 (n=6), and concentrations of cytokines were measured using Bio-Plex. Black bald line shows averages and open circle shows values for individual mice. *p<0.05. (B) Histological changes in the synovium of the hindlimb joint with score 0 from wild type (WT) (n=7) and gp130F759 (n=6) at 5–5.5 months old were estimated by degrees of neovascularisation (Nv), hyperplasia (Hp) and fibrosis (Fb) as described in Materials and methods section. The average and individual scores are indicated as horizontal bars and circles, respectively. *p<0.05. (C) Haematopoietic cell numbers in the synovium obtained by collagenase treatment and the spleen from WT (open bars) and gp130F759 (black bars) were analysed by flow cytometry. (D) Titres of CRP, RF-IgM, anti-circular citrullinated peptide (CCP)-IgM and anti-CCP-IgG antibodies in the sera of WT (open bars) and gp130F759 (black bars) were measured from 4 to 12 months old. *p<0.05. CRP, C reactive protein; Fb, fibrosis; Hp, hyperplasia; Nv, neovascularisation.
