Popis: | We investigated the activity of peptidases in the serum of mice with experimental polyarthritis that was induced by the injection of type II collagen, an experimental model of human rheumatoid arthritis. The activity of dipeptidyl peptidase II (DPP II) was increased and that of dipeptidyl peptidase IV (DPP IV) was decreased resulting in the significant increase of the serum DPP II DPP IV ratio in the polyarthritic mice compared with that of controls. These results indicate that the DPP II DPP IV ratio is a novel index of disease activity in mice with collagen-induced polyarthritis and may be useful in assessing the activity of rheumatoid arthritis in humans. |
