Nowadays, there are five known types of anti-IDs: α, β, γ, ", and δ. Due to the ability of internal-image anti-IDs to compete with an antigen for binding to antibody and to alter the biologic activity of an antigen, anti-IDs have become a target in the search for new treatments of autoimmune illnesses, cancer, and some other diseases. In this review, we summarize the data about anti-IDs that mimic the structural and functional properties of some bioregulators (autacoids, neurotransmitters, hormones, xenobiotics, and drugs) and evaluate their possible medical applications. The immune system is potentially able to reproduce or at least alter the effects of any biologically active endogenous or exogenous immunogenic agent via the anti-idiotypic principle, and probably regulates a broad spectrum of cell functions in the body, being a kind of universal remedy or immunacea, by analogy to the legendary ancient goddess of universal healing Panacea (Pανα´κεια, Panakeia in Greek) in the treatment and prevention of diseases, possibly including non-infectious somatic and even hereditary ones. Keywords: anti-idiotypic antibodies; agonistic autoantibodies; autacoid; drug; hormone; neurotransmitter 1. Introduction In 1900, London and Besredka demonstrated the existence of physiologic antihemolysins. In fact, these were anti-idiotypic autoantibodies (anti-IDs) against hemolysins. The authors immediately suggested their regulatory role [1]. Much later experimental anti-IDs were obtained by Kryzhanovsky et al. (1960) [2] and by Oudin (1963) [3]. In 1973, Lindenmann speculated that some anti-IDs may serve as homobodies or internal immunological mirror images of appropriate antigens [4]. The interest in anti-IDs started to increase with the proposal of the network theory of the immune system by Jerne in 1974 [5]. The main idea was that Ab can both recognize an antigen and in turn also be recognized by another Ab towards its paratope (Figure1).

DECISION1 On January 24, 2014, Michael Pavan (“petitioner”), as next friend of J.P., a minor, filed a petition in the National Vaccine Injury Compensation Program.2 Petitioner alleges that as a result of J.P. receiving the varicella vaccination on January 28, 2011, he suffered a significant aggravation of his Chronic Inflammatory Demyelinating Polyneuropathy (“CIDP”). Amended Petition at ¶¶ 4, 5, & 16 (ECF No. 26); Petitioner’s (“Pet.”) Post-hearing Brief at 2 (ECF No. 151). Based on a full review of the evidence and testimony presented, I find that petitioner has not established by a preponderance of the evidence that the varicella vaccination significantly aggravated J.P.’s CIDP and therefore, compensation must be denied and the petition dismissed. 1 In accordance with the E-Government Act of 2002, 44 U.S.C. § 3501 (2012), because this opinion contains a reasoned explanation for the action in this case, this opinion will be posted on the website of the United States Court of Federal Claims.

  • Idiotype-Recognizing T Helper Cells That Are Not Idiotype Specific*
    IDIOTYPE-RECOGNIZING T HELPER CELLS THAT ARE NOT IDIOTYPE SPECIFIC* BY MARY McNAMARA AND HEINZ KOHLER From the Department of Molecular Immunology, Roswell Park Memorial Institute, New York State Department of Health, Buffalo, NY 14263 The network hypothesis (1) postulates that B and T cells interact via comple- mentary idiotypic structures (2). This assumption creates a satisfying symmetry in the immune system by which both compartments would use similar receptor structures encoded by a single pool of variable genes. Experimental support for the sharing of idiotypes between B and T cells has been substantial (3-6). Most of this evidence comes from the demonstration that an antiidiotype antibody functionally interacts with T cells or can bind to T cells or T cell factors. These findings, however, do not prove that T cell receptors or factors use the same genes as B cells. On the contrary, the recent failure to detect active gene rearrangements in specific T cell clones (7, 8) indicates that T cells use other than Ig genes (9). One approach to studying T cell receptors is to analyze their specificity and compare it with the specificity of B cells for the same determinant. With respect to the T-B interaction in the immune network, a comparative analysis of how B and T cells recognize idiotypes would address the question of T cell receptor specificity. In a previous study we found (10) that T helper cells which recognize idiotypes as carriers for a hapten-specific antibody response recognize the TEPC-15 (T 15) 1 proteins and MOPC-167 (M 167) equally well.

  • Regulation of Natural Antiallotype Antibody Responses by Idiotype Network-Induced Auto- Antiidiotypic Antibodies*
    REGULATION OF NATURAL ANTIALLOTYPE ANTIBODY RESPONSES BY IDIOTYPE NETWORK-INDUCED AUTO- ANTIIDIOTYPIC ANTIBODIES* BY L. SCOTT RODKEY AND FRANK L. ADLER From the Department of Pathology and Laboratory Medicine, The University of Texas Medical School at Houston, Houston, Texas 77025; and Division of Immunology, St. Jude Children's Research Hospital, Memphis, Tennessee 38101 Immunoglobulin (Ig) idiotypes have been the focus of intense study since they were first recognized by Kunkel et al. (1) and by Oudin and Michel (2) in 1963. Idiotypic epitopes may be involved in the complex array of self-limiting regulatory mechanisms that the immune system imposes upon itself. Regulation at the level of idiotype recognition has been postulated by Niels Jerne (3) to be a fundamental specificity- associated immunoregulatory system capable of controlling immune responses at both the afferent and efferent limbs. Idiotype network interactions have been shown to involve both the B cell and T cell compartments (4). Cosenza et al. (5) showed that helper T cells can express idiotypes and Hetzelberger and Eichmann (6), Eichmann et al. (7), and Bona (8) have shown that helper T cells can express antiidiotypic specificity. Suppressor T cells can express idiotypes as shown by Lewis and Goodman (9) and are also capable of expressing antiidiotype specificity as shown by Bona and Paul (10). T cells mediating delayed-type hypersensitivity have also been shown to express idiotopes (11). The allotypic markers on rabbit Ig have been used productively to obtain basic information on Ig structure, function, and regulation. Early work on the sharing of V- gene products by H-chains of several isotypes (12), on allelic exclusion (13), and on allotype suppression (14) has provided new insights and inspired continuing investi- gations.
