| abstractText | The role of inflammatory and specific immune responses in pristane-induced arthritis (PIA) was investigated in mouse lines produced by bi-directional selective breedings for maximal (AIRmax) or minimal (AIRmin) acute inflammatory reaction, comparing the outcome of PIA and the humoral and cellular response to hsp65. Symptoms of arthritis were detected in 50 % AIRmax mice 120 days after pristane injection, reaching a maximal incidence of 65 %, whereas only 7 % of AIRmin mice developed arthritis within an observation period of 200 days. The production of IgG antibody against hsp65 was found to be similar on both lines, although the IgG1 isotype was predominant in AIRmax, and IgG2a in AIRmin line. In vitro T cell proliferation to hsp65 was similar in the two lines, however, ELISPOT assays carried out soon after pristane treatment, demonstrated higher numbers of IL-6-, TNF-alpha- and IL-4-secreting cells in the spleen of AIRmax than in AIRmin mice, while higher numbers of IFN-gamma-producing cells were found in AIRmin mice. These results suggest a major participation of acute inflammatory mechanisms in the susceptibility to PIA. The genetic background which determines high or low AIR favors a Th2-like response in susceptible AIRmax and Th1-like response in resistant AIRmin mice at the initial phase of arthritis induction. |
