  • Antibodies are fixed by the steady domain to the Fc receptor's cytotoxic lymphocyte, and with hyper variable domain to proper antigen.
  • Monoclonal antibody's antineoplastic operation mechanism in rather difficult and includes the following components: - Alexine-dependant cytotoxicity; - Antibody-dependant cell's cytotoxicity; - Ab2 vaccines; - Phagocytosis (activated microphages only); - Receptors bloke (antireceptors); - Apoptosis,; - Intracellular effects The most significant are first three mechanisms. During the alexine- dependant cytotoxicity realization there is staged alexine system energization on the tumor cells surface.
  • C9 protein forms on the last stage and it is able to form a foramenin in cell's basal membrane that leads to the cell's death.
  • Second important mechanism is antibody-dependant cytotoxicity. During this process monoclonal antibody gets involved with proper antigen on the tumor cell surface using its hyper variable domain. The same way antibody's constant gene contacts cytotoxic lymphocyte's Fc-receptors, so-called "killers". The latter ones are capable of synthesizing and protein output and serine protease injuring cell's membrane. This protein (perform) is equal to C9 alexine system.
  • Third important antineoplastic mechanism of monoclonal antibodies is so- called Ab2 vaccine mechanism.

  • SA accomplishes transportation of low-molecular substances in tissues.
  • A-fetoprotein serves as a substitute for SA for embryos, frequently called embryonal SA's, and its function is most likely the same - transportation.
  • A-fetoprotein has exceptional affinity to the polyunsaturated fatty acids, substances essential for cell's membrane construction and special class of biologically active substance - prostaglandins. Most probable function of a-fetoprotein is selective connection of polyunsaturated fatty acids in placenta and their transportation from mother's blob to the embryo's blood and tissues. Polyunsaturated fatty acids are synthesized neither by embryo nor by adult and delivered in organism only by vegetal food.
