  • Theories of Antibodies Production
    THEORIES OF ANTIBODIES PRODUCTION 1. Instructive Theories a. Direct Template Theory b. Indirect Template Theory 2. Selective Theories a. Natural Selection Theory b. Side Chain Theory c. Clonal Selection Theory d. Immune Network Theory INSTRUCTIVE THEORIES Instructive theories suggest that an immunocompetent cell is capable of synthesizing antibodies of all specificity. The antigen directs the immunocompetent cell to produce complementary antibodies. According to these theories the antigen play a central role in determining the specificity of antibody molecule. Two instructive theories are postulated as follows: Direct template theory: This theory was first postulated by Breinl and Haurowitz (1930). They suggested that a particular antigen or antigenic determinants would serve as a template against which antibodies would fold. The antibody molecule would thereby assume a configuration complementary to antigen template. This theory was further advanced as Direct Template Theory by Linus Pauling in 1940s. Indirect template theory: This theory was first postulated by Burnet and Fenner (1949). They suggested that the entry of antigenic determinants into the antibody producing cells induced a heritable change in these cells. A genocopy of the antigenic determinant was incorporated in genome of these cells and transmitted to the progeny cells. However, this theory that tried to explain specificity and secondary responses is no longer accepted. SELECTIVE THEORIES Selective theories suggest that it is not antigen, but the antibody molecule that play a central role in determining its specificity. The immune system already possess pre-formed antibodies of different specificities prior to encounter with an antigen. Three selective theories were postulated as follows: Side chain theory: This theory was proposed by Ehrlich (1898).

Box 16040, Havana 11600, Cuba bMolecular Immunology Group, International Centre for Genetic Engineering and Biotechnology, Padriciano 99, 34012 Trieste, Italy Abstract: The use of anti-idiotypic antibodies for cancer treatment continues to be a major field of investigation. One ma- jor challenge for tumor immunotherapy is the identification of antigens associated only or preferably with malignant cells. We summarize here some of the most recent preclinical and clinical advances using two targets that can be considered tumor-specific antigens: N-glycolyl (NeuGc)-gangliosides and the idiotype of B cell lymphomas. Recent developments with tumor-associated protein antigens and the role of anti-idiotypic antibodies in autoimmune diseases are also discussed.

    Anti-idiotypic antibodies against a human multiple organ- reactive autoantibody. Detection of idiotopes in normal individuals and patients with autoimmune diseases. K Essani, … , P R McClintock, A L Notkins J Clin Invest. 1985;76(4):1649-1656. https://doi.org/10.1172/JCI112150. Research Article We have recently isolated and characterized a human monoclonal autoantibody, MOR-h1 (multiple organ-reactive human 1), that reacts with antigens in multiple organs and have shown that this antibody binds to human growth hormone and a 35,000-mol wt protein. In the present study we generated three monoclonal anti-idiotypic antibodies (4E6, 3E5, and 3F6) against MOR-h1. These anti-idiotypic antibodies specifically reacted with MOR-h1 and not with 26 other multiple organ- reactive monoclonal IgM autoantibodies nor with pooled human IgM (myeloma proteins). The binding of the anti-idiotypic antibodies to MOR-h1 was inhibited by both human growth hormone and the 35,000-mol wt protein, which strongly suggests that these antibodies react with epitopes at or near the paratope on MOR-h1. The results of competitive binding experiments revealed that the epitope recognized by 4E6 is distinct from that recognized by 3E5 and 3F6. Using these anti-idiotypic antibodies, lymphocytes and sera from normal individuals were tested for the presence of the 4E6 and 3E5/3F6 idiotopes. By indirect immunofluorescence, the 4E6 idiotope was detected on an average of 1.1% of normal circulating B lymphocytes, and by enzyme-linked immunosorbent assays, the 4E6 and to a lesser extent the 3E5/3F6 idiotopes were found on IgG molecules in sera of normal individuals.

  • The Antibody Response to Specific Immune Complexes Is Under Genetic Control and Correlates with the Expression of a Recurrent Idiotype
    THE ANTIBODY RESPONSE TO SPECIFIC IMMUNE COMPLEXES IS UNDER GENETIC CONTROL AND CORRELATES WITH THE EXPRESSION OF A RECURRENT IDIOTYPE BY MICHAEL J. CAULFIELD, KATHLEEN J. LUCE, DIANA SHAFFER AND JEFFREY P. LAKE* From the Department of Molecular and Cellular Biology, Cleveland Clinic Foundation, Cleveland, Ohio 44106; and the *Department of Pathology, The Jewish Hospital of St. Louis, St. Louis, Missouri 63110 In the natural selection theory of antibody formation (1), Jerne proposed that the "antigen is solely a selective carrier of spontaneous circulating antibody to a system of cells which can reproduce the antibody." Although proposed before the nature of the antigen-reactive cell was known, the hypothesis has proved to be remarkably accurate in its predictions. Central to the theory is the prediction that natural antibody exists prior to exposure to an antigen, and that the subsequent response is composed of antibody that is identical to that which interacts with the antigen in the first place. This study was undertaken to test this prediction by examining the antigen-specific antibody response to preformed immune complexes. Specifically, we wished to determine whether the response to the antigen is influenced by allotypic or idiotypic determinants on the antibody used to form the immune complex. Our approach has been to examine the immunogenicity of preformed antigen/antibody complexes in strains of mice that have different immunoglobulin heavy chain allotypes and in strains that express either high or low levels of the relevant idiotype. In the network theory, Jerne suggested (2) that recognition of self-idiotopes forms the basis of an immunoregulatory network.

    Naveed et al. Translational Medicine Communications (2018) 3:1 Translational Medicine https://doi.org/10.1186/s41231-018-0021-4 Communications REVIEW Open Access Recapitulation of the anti-Idiotype antibodies as vaccine candidate Ahsan Naveed1*, Sajjad Ur Rahman1, Muhammad Imran Arshad1 and Bilal Aslam2 Abstract The foreign antigen that enters into the body is detected by the immune system through antigen presenting cells leading to the production of antibodies. The use of anti-idiotype antibodies is a new way to excite the immune response that identifies and eliminates the foreign antigens entered into the body. These Anti-idiotype antibodies have the ability to decrease the non-specific binding of the antigenic protein epitopes because of high specificity for the antigenic determinants. The anti-idiotype antibodies attach to the paratope of idiotype antibody and stimulate a precise immune reaction same as that of external antigen. The anti-idiotype antibodies are the peerless therapeutic candidate as they mimic the antigenic structure and potentiate antibody and cell-mediated immunity. Even in the absence of foreign antigen, these anti-idiotype antibodies have the potential to provide long-lasting immunity. The present review is about immune regulations by anti-idiotype antibodies with some success therapeutic stories. The previous research analysis is evidence of anti-idiotype antibodies as an excellent candidate for the development of both human and animal vaccines although it has some gaps that are needed to be addressed.
