| immunotoxins | Semisynthetic conjugates of various toxic molecules, including radioactive isotopes and bacterial or plant toxins, with specific immune substances such as immunoglobulins, monoclonal antibodies, and antigens. The antitumour or antiviral immune substance carries the toxin to the tumour or infected cell where the toxin exerts its poisonous effect. (12 Dec 1998) |

| immunotransfusion | An indirect transfusion in which the donor is first immunised by means of injections of an antigen prepared from microorganisms isolated from the recipient; later, the donor's blood is collected, defibrinated, and then administered to the patient; the latter is then presumably passively immunised by means of antibody formed in the donor, e.g., antibody that reacts with the microorganisms in the patient.
