Never has so much progress been reported in immunology as at this congress. The full impact of new technologies, developed since the late 1970s, has come to fruition: gene isolation, mutation, transfection and expression, protein structure and peptide synthesis, cell cloning, hybridization and monoclonal antibodies, CD serology, SCID and transgenic mice, modern immunomudulation and vaccines. An overwhelming mass of data has accumulated over the last years. The reports are up-to-date and outstanding, to a degree no journal will ever achieve, and the results are presented in a concise and lucid way. This report will serve as a guideline for generations of immunologists to come. Hundreds of new alleys have been opened, an abundance of research tools and goals are pointed to. This volume is a treasure trove of explorations ahead of our time - it is exciting reading. This progress report presents outstanding contributions, worth many prizes - a feature which is unusual for proceedings volumes. Immunology is exhibited at its best: an exciting research area and a rewarding subject to study for the benefit of mankind - today more than ever!

Progress in Immunology

The 12th Workshop on ""Mechanisms in B-Cell Neoplasia"" continues this series of meetings on intriguing new developments in human and experimental B-cell tumors. The integration of knowledge from basic B-cell biology to the clinical problems of multiple myelomas, follicular lymphoma, mantle cell lymphoma and B-CLL present the challenges that were discussed in the meeting. The discussion focusses on: - Cellular components of the "myeloma clone" - Genomic instability in B-cells and B-cell tumors - The CD5 antigen and B1 cells - Regulation of cell cycle and apoptosis - Role of IL-6, BCL-2, BCL-1, myc in B-cell development

Mechanisms in B-Cell Neoplasia

Workshops on the mechanisms of B cell neoplasia have been organized alternatively in Bethesda and Basel since 1983. Prog ress in our understanding of the development and responses of B lymphocytes is presented and discussed with the aim and hope to understand what might go wrong when B lymphocytes are transformed into malignant cells. Such knowledge might lead to better diagnosis, prevention and even cure of these terri ble diseases. The presentations at the Bethesda workshops are published as papers in volumes of Current Topics in Microbiol ogy and Immunology, while the presentations and discussions in Basel were transcribed and published in Editions Roche. For the first time, a Basel workshop (held 4th-6th October 1998) that has been recorded and, in part, transcribed is being published as papers and discussions within Current Topics. This volume is the latest of a long series which documents the excitements of ground-breaking discoveries as well as the frustrations of our inability to fully understand the mechanisms leading to B cell neoplasia. The papers at the workshop are presented when possible in the sequence in which they were given. However, to facilitate the organization and reading of the book and to highlight gen eral topics and themes, the papers are organized into five sec tions: I B Cell and Plasma Cell Development II Chemokines and Chemokine Receptors III Chromosomal Translocations, DNA Rearrangements and Somatic Hypermutations IV Biology of Lymphomagenesis, B-CLL, Autoimmunity V Myeloma, Plasmacytomas and Related Subjects.

In recent years, major developments have increased understanding of various genetic and epigenetic regulatory processes that are critical for the generation of B cell repertoires. These include the role of chromatin regulation and nuclear organization in understating the IgH gene regulation. These proceedings highlight recent developments in lymphocyte development, Ig gene rearrangements and somatic hypermutation, chromatin structure modification, B lymphocyte signaling and fate, receptor editing, and autoimmunity.

The intestine is colonized by an impressive community of commensals, that has profound effects on the immune funtions. The relationship between gut microbiota and the immune system is one of reciprocity: commensals have important contribution in nutrient processing and education of the immune system and conversely, the immune system, particularly gut-associated lymphoid tissues plays a key role in shaping the repertoire of gut microbiota.

Gut-Associated Lymphoid Tissues

It has been clear for a long time that after transplantation of a lymphoid organ, hematopoietic stem cells can regenerate the compartments of the organ, provided that the rest of its architecture - the strome, the epithelia and the vessels - is intact. Ahead lies the even greater challenge to assemble also these other architectural elements of a lymphoid organ by transplanting stem cells. The workshop on lymphoid organogenesis was convened to review current knowledge of and experimental skills involved in this grand project to build a lymphoid organ from its individual cellular components.

Lymphoid Organogenesis

Hilary Koprowski

The diversity of antigen-binding structures of antibody molecules is so vast that every conceivable antigen can be bound by an antibody molecule within the immune system. This is true even for the antigen binding sites of antibodies called idiotypes, which are bound by complementary bind ing sites of other antibodies called anti-idiotypes. Thus, anti-idiotypes are structural homologues of antigens. These idiotypic-anti-idiotypic interactions constitute a network within the immune system. Since one lymphocyte produces only one type of antibody molecule, this network is in fact a network of cells. We expect that the network is functional: the appearance of antigen will disturb the equilibrium of the network at the point where it competes with the anti idiotypic lymphocyte for binding to the idiotypic lympho cyte. It has been known for quite some time that anti idiotypic antibody can be used to prime the immune system for memory to an antigen that it has never seen. This phe nomenon is now being explored for possible use in immuni zation against viruses, bacteria, parasites and tumors as well as for the modulation of autoimmunity. The ability of anti-idiotypes to mimic, both antigenically and function ally, the corresponding biologically active molecules seen by an idiotypic antibody was first demonstrated for the hormone insulin and is now being observed in many other systems. The papers assembled in this volume· bring the reader to the cutting edge of the potential practical applica tions of the network theory of the immune system.

Mechanisms of B Cell Neoplasia 1989

The papers in this book were presented at the 14th Mechanisms in B-cell Neoplasia meeting that was held in Bethesda, Maryland October 21-23, 1996. In 1995 the organizers decided that the format of the meeting would be changed and that specific topics relevant to B-cell neoplasia would be discussed. This year's topic is on the c-myc oncogene in B-cell neoplasia which has been discussed in virtually every previous meeting. Some of the presentations announced for the first time dramatic advances in our understanding of c-myc and because this subject has become highly complex it was thought that devoting the whole meeting to this theme would be appropriate. The book, therefore, repre sents a review of many aspects of the myc problem but by no means is truly comprehensive. In a recent Medline search there were 8,505 references to myc, fully illustrating the magnitude of the interest and depth of this field. The organizers of the meeting have each contributed review chapters that summarize different aspects of the meeting. We thank the National Cancer Institute for sponsoring this workshop and the staff of Cygnus, Inc. , for their outstanding organizational assistance. The organizers are most grateful to Vickie Rogers for assembling the book and dealing with the edi torialization of the manuscripts. MICHAEL POlTER FRITZ MELCHERS Table of Contents M. POlTER and K.
