A tumor immunotherapy technique based on modulation of the idiotype anti-idiotype network. 1985

R J Sharpe

In this communication I propose a technique for manipulating the idiotype anti-idiotype network with the aim of enhancing the immune response to tumors. The theoretical basis for this technique follows from Jerne's network theory of the immune system. By tolerizing the host to immunoglobulin bearing idiotypes directed against tumor associated antigens it should be possible to dampen the expected anti-idiotype response to these idiotypes. A reduced anti-idiotype response should result in an increased idiotype response and thus a greater anti-tumor immune response.

UI	MeSH Term	Description	Entries
D007130	Immunoglobulin Idiotypes	Unique genetically-controlled determinants present on ANTIBODIES whose specificity is limited to a single group of proteins (e.g., another antibody molecule or an individual myeloma protein). The idiotype appears to represent the antigenicity of the antigen-binding site of the antibody and to be genetically codetermined with it. The idiotypic determinants have been precisely located to the IMMUNOGLOBULIN VARIABLE REGION of both immunoglobin polypeptide chains.

D007167	Immunotherapy	Manipulation of the host's immune system in treatment of disease. It includes both active and passive immunization as well as immunosuppressive therapy to prevent graft rejection.	Immunotherapies
D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008954	Models, Biological	Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.

D001402	B-Lymphocytes	Lymphoid cells concerned with humoral immunity.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
