Ir Genes and Ia Antigens features papers that were presented at the Third Ir Gene Workshop held in Asilomar, California, December 13-16, 1976. The book is organized into seven parts that correspond to the seven sessions held during the workshop. The first session focused on the definition of the I-E and I-C subregions, and the mapping and cellular expression of complementing Ir genes. The second session included papers on the expression of gene products of the I region. The third session covered two major areas: (1) the biochemical characterization and primary structure of la antigens; and (2) the possible carbohydrate nature of la antigenic determinant. The studies presented in the fourth session focused on the role of I-region gene products in cellular interactions. The fifth session discussed the "recognition" functions controlled by the I region of the major histocompatibility complex (MHC). The sixth session featured papers on la-containing T cell factors. Finally, the seventh session examined the properties of T-cell antigen receptors.

The Fifth Ir Gene Workshop was held at the Chase-Park Plaza Hotel, St. Louis, MO, August 28-31, 1982; 240 scientists participated in the Workshop. The man uscripts compiled in this book describe the state of the art concerning Ir genes. Although the notion of Ir Genes: Past, Present, and Future has not been ad dressed specifically by each author, the reader is certain to get this flavor from the contributions. In this Preface, we have tried to summarize some of the salient ob servations and discussions from the Workshop. The mUltiple genes of the I region have been defined traditionally by serolog ical analysis of intra-H-2 recombinant mice and the pattern of immune responses to certain antigens developed by these recombinant mice. The application of sev eral new techniques, such as gene cloning and DNA sequencing, production of T and B cell hybridomas, and development of cloned T cell lines has changed this tradition and introduced a new phase into the analysis of the I region, Ia antigens, and Ir genes.

The purpose of this book is to provide the reader with a ready source of information regarding Ia antigens in several animal species.The significance role played by the gene products of I regions in cell-cell interactions has stimulated interest in the characterization of Ia antigens. Through the effort of several investigations much information about the functional and structural properties of Ia antigens has been accumulated in recent years.

Details the latest understanding of the immune system. Although material is geared toward advanced study, basic elements and concepts are discussed, making this a useful resource for both immunologists and nonspecialists as well as advanced students. Contains chapters on genes of the major histocompatibility complex, genes of the antigen processing pathways, T- and B-lymphocyte genes, autoimmune disorders, neoplasias involving translocation of antigen receptors genes, cytokines of the immune system, and leukocyte cluster of differentiation antigens.

The Role of Products of the Histocompatibility Gene Complex in Immune Responses documents the proceedings of a conference held on 3-7 November 1975, which brought together an international group of scientists spanning three independent disciplines—genetics and immunogenetics, molecular biochemistry, and immunobiology—with clinical medicine overlapping these disciplines. This volume contains 42 papers organized according to the eight sessions held at the conference. The papers in Session I examined the genetics of the major histocompatibility complex. Session II presented studies on the biology of mixed lymphocyte interactions and cell-mediated cytotoxicity reactions. Session III discussed immune response gene systems while Session IV dealt with the genetic control of cell interactions. The papers in Session V covered idiotypic determinants on T cell receptors. Session VI investigated the properties of histocompatibility gene products involved in regulation of immune responses. Session VII focused on the biochemistry and immunocytology of cell surface products of the major histocompatibility complex. Finally, Session VIII discussed interrelationships between products of the major histocompatibility complex and their relevance to disease.
