immunotoxin

immunotoxin
n.
one of a class of compounds undergoing clinical trials for the treatment of certain cancers. Therapeutic immunotoxins combine monoclonal antibodies, which can specifically target cancerous cells, with a highly toxic compound (such as ricin) that inactivates the cells' ribosomes and thus inhibits protein synthesis. Because the toxin does not attack the whole cell only tiny amounts are required.
