Appendix

Definitions

Immunotoxins are targeted drugs made from coupling the toxin with either an antibody or a targeting moiety that recognizes only a diseased cell, often malignant cancer cells while spares non-infected, nonmalignant, host tissue; and thus could use for all cases requiring treatments via targeted medicine or targeted surgery and for several illnesses like the treatments of all cases of various forms of autoimmune and cancer illnesses.
