DP8 and DP9 are proteases with diverse functions including cell interactions, apoptosis, and immune response but their localization remains to be clarified. We assessed the impact of DPP IV/CD26 deficiency (CD26-/- ) on the expression profiles of DP8 and DP9 by qPCR and immunodetection as well as quantified DP8/9 enzyme activity in distinctive phases of a chemically-induced CD model in mice. CD26-/- did not affect colon DP8 mRNA expression, while the physiological concentration of DP8 protein is decreased in CD26-/- mice but rises in inflammation (P < 0.05). On the other hand, DP9 mRNA level is significantly increased in CD26-/- mice in inflammation as well as healing with the DP9 concentration being almost twofold increased (P < 0.05) in all experimental points in CD26-/- mice compared to wild-type indicating the expected up-regulation in CD26-/- conditions. Surprisingly, dominantly intracellular DP8 and DP9 were found in abundance in serum. DP8/9 activity is decreased in the inflamed colon, whereas its contribution to the overall serum DPP IV/CD26-like activity is negligible, suggesting the importance of their extra-enzymatic functions. To summarize, CD induction generated gene, protein and enzymatic changes of DP8 and DP9 so their involvement in inflammation development and/or healing process is implicated, especially in CD26-/- , and the question of their subcellular localization should be revised."xsd:string |
