begelomab

A monoclonal antibody against the human dipeptidyl peptidase 4 (dipeptidylpeptidase IV, DPPIV, DPP4; CD26), with potential activity against graft-versus-host disease (GvHD). Upon administration, begelomab binds to CD26 expressed on T cells. This inhibits the stimulation of T cells and may prevent GvHD. CD26, a membrane-bound glycoprotein with dipeptidyl peptidase activity, plays a key role in T-cell activation and immune regulation.
