A drug such as Remicade (Ritindmab) which is widely used in treating oncology patients has a number of different activities; its likely the most important function of the drug is to link the Fc portion of Remicade to the patients Natural Killer cells and mediate Antibody Dependant Cell Cytotoxicity and Complement Dependant Cytotoxicity these activities are important in killing the cancer cells, Rituximab has also been shown to increases MHC II and adhesion molecules, it elicits shedding of CD23, it down regulates the B cell receptor and it induces apoptosis of CD20+ cells.
