Targeted delivery of saporin toxin by monoclonal antibody to the transcobalamin receptor, TCblR/CD320.


Cellular uptake of cobalamin (Cbl) occurs by endocytosis of transcobalamin saturated with Cbl by the transcobalamin receptor (TCblR/CD320). The cell cycle-associated overexpression of this receptor in many cancer cells provides a suitable target for delivering chemotherapeutic drugs and cytotoxic molecules to these cells while minimizing the effect on the… (More)
