Idiotypes documents the proceedings of an International Conference on Idiotypes held in Oklahoma City, Oklahoma, at the Oklahoma Medical Research Foundation, October 20-23, 1985. The aims of the conference were to gather active investigators in the study of idiotypes; to assess progress in the field; and to explore directions for future research. The papers presented at the conference cover a wide range of subjects. Several papers deal with defining protein and DNA sequences which determine idiotypes. Evidence points to germ line genes encoding the V region structures which underlie idiotypy. Another subtheme which concerns several contributions is the occurrence of dominant idiotypes in induced immune responses (e.g., arsonate and lysozyme) and autoimmunity (e.g., thyroglobulin and rheumatoid factors). The presence of such dominant idiotypes is discussed from several viewpoints, but the recurrent theme is that such dominance is a manifestation of a selection process inherent in the idiotypic network. Two papers deal with idiotypic structures in T cells: on the one hand, identifying idiotypes on T helper cells and, on the other, I-J and Iat related structures which tightly govern cellular interactions in the evolution of an immune response. Network interactions through autoanti-idiotypic responses are shown to be associated with the effects on the specificity of both induced and naturally occurring immune responses. Autoanti-idiotypic responses are also shown to be correlated with the regulation of the anti-DNA response in human systemic lupus erythematosus. These data pointed to a role of the idiotype network in immune regulation.

The phenomenon of idiotypy was discovered almost thirty years ago, but it was only during the past decade that it attracted widespread interest and became the subject of numerous research investigations. From the outset, much of the interest in idiotypy was based on its implications with respect to the repertoire of antibodies. Kunkel showed, for example, that idiotypes associated with certain human myeloma or Bence-Jones proteins were present in normal human globulins at levels of less than one part per million. Also, Oudin's original definition of idiotypy implied that idiotypes could be uniquely associated with individual rabbits as well as with particular antigen-binding specificities. Such observations provided some of the earliest evidence for an extensive repertoire of immunoglobulin molecules. The implications of these findings have been amply confirmed by recent studies of protein struc ture and molecular genetics; many of these studies are reviewed in the present volume. It is known now that the diversity of antibodies is based on the presence of numerous V and L V H genes, on recombinatorial events involving D and] segments, on somatic mutations, and on processes involving deletion of DNA followed by repair with errors, including inser tions. Each of these parameters is capable of influencing the idiotype expressed by the final immunoglobulin product. Regulation of the immune response is another area in which idiotypy has significantly influenced modern immunology.

Idiotypy in Biology and Medicine aims to serve the increasing interest and involvement in the practical aspects of idiotypy in biological systems. The concept of idiotypy has received wide recognition and interest far beyond the area of immunology. Experiments and interpretation of findings, reported here, clearly support the general nature of the idiotype concept in manipulating biological systems to correct pathological conditions or to improve the immune adaptation to environmental factors. The book is organized into three sections. Section 1 discusses original concepts of idiotypic manipulations. It reviews old and recent data important for the concept of an idiotype network and reports on attempts to deal with the T-cell receptor paradox; explains the immune system in terms of a circular idiotype network that can be demonstrated by sequential immunization; and emphasizes the need for restrictions in network interactions. Section 2 addresses the role and activity of idiotypic and antiidiotypic antibodies in the regulation of the immune system. Section 3 takes the issue of idiotype-antiidiotype out of the realm of the immune system and discusses it as a new principle to analyze and manipulate biological systems in general.

This publication is based on a Symposium that has been held in Clearwater, Florida on February 19-21, 1986, on antibodies, their structure, synthesis, function, and clinical applicability in disease. Organization of this symposium by the University of South Florida College of Medicine was prompted by the unparalleled current expansion of information on these topics in general, and in the field of antibody diver sity, in particular. The issues that surround the last named dimension of this field, began to surface in the late 1950's with the first conclusive genetic studies having been answered, and a new set of concepts has been de fined. As we see it from the material presented in this volume, now new and different questions are being raised and answered by studies in progress, and it may be expected that there will be other questions that will be with us for a considerably longer time. We believe that the symposium brought together many prominent investi gators with different backgrounds and training experiences such as immunolo gists, microbiologists, biochemists, molecular biologists, and clinical sci entists, thus providing an excellent example of the interdisciplinary value of modern immunology and modern biomedical science in general. We believe, therefore, that bringing these complex topics to a wide audience of bio medical scientists through this symposium as well as this volume is of value to the scientific and to the medical community.

The goal of this book is to present findings which are supportive of the concept that the words of the idiotype dictionary and likewise self-recognition are essential for communication between lymphocyte clones while some unfaithful ( infidel ) copies of the words contained in the idiotype dictionary perhaps play a role in the functional regulation of nonlymphoid cells.

RICHARD J. GLASSOCK Introducing a scientific symposium is an uncertain and difficult task. The remarks must not be too specific lest the participant's later contributions be intruded upon, yet an overview of the goals and objectives of the conference should be presented in an inquisitive and stimulating fashion. Perhaps a compromise position would be to make a few general statements and pose a limited number of questions which hopefully would then be addressed dur ing the formal or informal portions of the meeting. A conclusion incorpo of the relevance of the specific topic to the more rating some perspectives global issues of disease and its consequences might be appropriate. The goals and objectives of this conference, as set forth by its organizers, Professors Ponti celli, D'Amico and Minetti, are rather simple and straight forward; namely, to review and elucidate the immunopathophysiology of cryoimmunoglobulins and auto-antibodies to immunoglobulins (lg) and, secondarily, to explore the possible participation of these disordered states in glomerular injury. As such, this conference is principally devoted to an analysis of two properties of certain species of the globulin fraction of serum proteins, specifically the ability to self associate on the basis of immune interactions and to form insoluble aggregates when exposed to reduced ambient temperature. As we shall see, these two properties are often dis tinctly related.

This volume contains the contributions to the workshop "The Semiotics of Cellular Communication in The Immune System" which took place at "11 Ciocco" in the hills north of Lucca, Italy, September ~-12, 1986. The workshop was the first meeting of what we hope will be a broad consideration of communication among lymphocytes, and focused on the new interdisciplinary branch of biological sciences, immunosemiotics. It is in the realm of the possible, if not the probable, that in the future a number of scientists larger than the thirty present at 11 Ciocco will find immunosemiotics to fill a need in scientific thinking and a gap between biology and the humanities. This might lead to growth and flourishing of the branch, and in this case the first conference and this first book could be blessed by the impalpable qual ity of becoming "historical", if in an admittedly 1 imited sense. Just in case this should happen the organizers/editors think it wise to set the record straight at this particular time, about the sequen~e of events and circumstances that crystallized the archeology of the "11 Liocco" gathering. They feel a sort of obligation to this endeavor: it has happened all too often that innocent historians have been left in utter confusion by the careless founders of new religions, schisms, revolutions, et cetera, who simply forget to jot down the facts before the whirlwind of time engulfs them in its fog.
