Blood Cancer

What is antibody therapy?

Antibodies are generated by immune cells in the body. They recognise and attach themselves to the surface structures (antigens) of pathogens. Cells that are flagged in this way are identified by other immune cells as hostile and destroyed.

More and more blood cancers can now be treated with artificially produced antibodies, particularly non-Hodgkin lymphoma (NHL), and also chronic lymphocytic leukaemia (CLL). They work on the basis of a 'lock and key' principle: the available antibodies are the key and work only on cancer cells with a matching lock, or antigen. If lock and key don’t match, the therapy will not work.
