Serum dipeptidyl aminopeptidase IV (DAP IV) activity in rats with adjuvant arthritis (AA) were studied. DAP IV activity was significantly low in AA rats (37.7 +/- 14.1 mU/ml, n = 15) compared with control (63.7 +/- 9.0 mU/ml, n = 8) and indomethacin-treated (IDM) AA rats (55.6 +/- 14.2 mU/ml, n = 15). In addition, serum DAP IV activity was inversely correlated with hindpaw arthritis score both in AA rats and IDM-AA rats. Among serum inflammatory index examined, acid soluble glycoprotein, sialic acid were inversely correlated and albumin was positively correlated with DAP IV activity in AA and IDM-AA rats. The role of serum DAP IV remains unknown, but, it seems possible that DAP IV might modify the clinical course of AA rats in connection with its effects on the immune regulatory system.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001169 Arthritis, Experimental ARTHRITIS that is induced in experimental animals. Immunological methods and infectious agents can be used to develop experimental arthritis models. These methods include injections of stimulators of the immune response, such as an adjuvant (ADJUVANTS, IMMUNOLOGIC) or COLLAGEN.

D018819 Dipeptidyl Peptidase 4 A serine protease that catalyses the release of an N-terminal dipeptide. Several biologically-active peptides have been identified as dipeptidyl peptidase 4 substrates including INCRETINS; NEUROPEPTIDES; and CHEMOKINES. The protein is also found bound to ADENOSINE DEAMINASE on the T-CELL surface and is believed to play a role in T-cell activation.
