WebActivated T lymphocytes express high levels of dipeptidyl peptidase IV (DP IV)/CD26. Recent studies support the notion that DP IV may play an important role in the regulation of differentiation and growth of T lymphocytes. This article gives a short overview on DP IV/CD26 expression and effects on immune cells in vitro and in vivo.
