Rapid progress continues to be made in understanding the molecular and cellular events that comprise B-Iymphocyte differentiation. This is due in part to the high level of inter est shown by many investigators from diverse disciplines, who find this subject suitable for addressing some of the fundamental issues of immunobiology. B-cell developmen tal models are being extensively used to investigate cell-cell interactions, molecular mediators of differentiation and proliferation, differential onset of gene programs, and gene rearrangement and expression, as well as the generation of the immune response itself. Not surprisingly, increased understanding of B-cell differentiation sometimes results from the application of new techniques that permit greater insight into the cells comprising the system and the genetic mechanisms by which these cells express their differentiative potential. However, experimental strategies based upon the novel application of established technologies have also led to the clarification of many issues, as well as to the discov ery of previously unrecognized problems. One problem, well recognized by those active in the field, is how to keep up with significant developments as they appear. The purpose of this book, part of a series devoted to analysing current issues in biology, is to help overcome this problem. No attempt at comprehensive cov erage of all of the issues has been made. Rather, a more thorough analysis of a few topics is presented.

Signal Transduction and the Coordination of B Lymphocyte Development and Function I

Proper development and differentiation of B lymphocytes is es sential to ensure that an organism has the ability to mount an effective humoral immune response against foreign antigens. The immune system must maintain a balance between the deletion of harmful self-reactive B cells and the generation of a diverse rep ertoire of B cells that has the ability to recognize an almost un limited array of foreign antigens. The need to delete self-reactive cells is tempered by the need to avoid the generation of large functional holes in the repertoire of foreign antigen-specific B cells that patrol the periphery. To accomplish this, the immune system must reach a compromise by eliminating only the most dangerous autoreactive clones, while allowing less harmful au toreactive B cells to exist in the periphery where they may com plement the organism's ability to mount a rapid response against invading micro-organisms. Those autoreactive cells that do enter the peripheral pool are subject to a number of conditional re straints that effectively attenuate their ability to respond to self antigens. Deleterious alterations in the homeostasis between tolerance induction and recruitment of B cells into the functional repertoire may lead to increased susceptibility to autoimmune disease or infection, respectively. Therefore, delineation of the molecular processes that maintain immunological homeostasis in the B cell compartment is critical.

The progress in protein and nucleic acid chemistry together with improvements of the previously employed tissue culture techniques have led to the solution of problems such as that of the generation of antibody diversity or of the molecular structure of T and B cell membrane receptor for antigen which had challenged the past generations of immunologists. Thanks to this progress an impressive amount of knowledge has been accumulated on certain cell types that were relatively "mysterious" until recently. The B lymphocyte represents a typical example of such a cell. With these considerations in mind, we have started to organize a NATO summer school on "The molecular basis of B cell differentation and function" that had the specific aim of bringing up to date a selected number of young investigators. During the course, held in Santa Margheri ta Ligure, October 1-11, 1985 it became apparent that rather than a formal school we had organized an informal series of Workshops where both the Faculty members and the participants were discussing their own data in addition to reviewing the general progress in the field. The deep commi ttment of everyone to his research subj ect and the enthusiasm had caused this very successful change in the shape of the course. At the end we asked the members of the Faculty and the participants to write a summary of their data and of their point of view on selected subj ect s.

T Cell Dependent and Independent B Cell Activation

This book provides an analysis of the current subdisciplines comprising the study of humoral immune response. The first chapter presents a detailed discussion regarding the experimental and conceptual studies conducted prior to the mid-1970s that have served as a valuable research framework for investigators interested in the process by which B cells are activated following their exposure to antigens. Other chapters focus on topics such as membrane-associated proteins with important functional roles during B cell activation and differentiation; thymus-independent and thymus-dependent activation; mechanisms operative during B-T cell interactions, including the role of B cells as antigen-presenting cells; and the importance of soluble mediators. Additional topics include the regulatory role of T cells during B cell repertoire expression, memory development, tolerance, and autoimmunity. T-Cell Dependent and Independent B-Cell Activation is an important history and reference resource for humoral immune response investigators, as well as advanced graduate and medical students.

This book contains twelve chapters contributed by prestigious international experts who are at the forefront of B cell research, and aims to provide a cutting-edge and comprehensive overview of all aspects of B cells, including B cell development, maturation and activation, germinal center reaction, memory and plasma cell differentiation, and antibody-mediated positive and negative regulation of humoral immune responses. There are also three chapters describing human diseases caused by B cell abnormalities, including primary antibody deficiencies, autoimmune diseases, and B cell malignancies. We hope that this book will become a standard and routine reference for both basic researchers and clinicians.

The Origin of the Plasma Cell Heterogeneity

Plasma cells (PCs) are terminally differentiated B-cells producing large amounts of immunoglobulins (Ig). In humans, most of circulating Ig are produced by bone marrow plasma cells. PCs differentiate from activated naïve or memory B-cells usually activated by specific antigens. It is still controversial whether the regulation of PCs numbers and the “active” in vivo Ig diversity depend or not on non-specific reactivation of B-cells during infections. Depending on the stimulus (T-independent/T-dependent antigen, cytokines, partner cells) and B-cell types (naïve or memory, circulating or germinal center, lymph nodes or spleen, B1 or B2...), both the phenotype and isotype of PCs differ suggesting that PC diversity is either linked to B-cell diversity or to the type of stimulus or to both. Knowledge of the mechanisms supporting PC diversity has important consequences for the management of i) plasma cell neoplasia such as Multiple Myeloma and Waldenström's Macroglobulinemia, ii) vaccine protection against pathogens and iii) auto-immune diseases.
