Anti-CD26 monoclonal antibodies can reversibly arrest human T lymphocytes in the late G1 phase of the cell cycle.


Three different anti-CD26 monoclonal antibodies (mAbs) are described, which specifically inhibited proliferation of human T lymphocytes after stimulation with PHA, tetanus toxoid or soluble anti-CD3 mAb. Anti-CD26 mAbs induced in T cells a dose-dependent shift of the maximum of DNA synthesis, which was due to a transitory arrest of cells in the cell cycle… (More)
