Book Description
The papers in this book were presented at the 6th Workshop on Mechanisms in B-Cell Neoplasia, held in Bethesda, March 23-25, 1988. On alternate years this meeting is sponsored by the . ;. Basel Institute of Immunology in Basel, Switzerland and by the National Cancer Institute in Bethesda, and is attended by 100 to 150 parti cipants. This 6th workshop, like the preceding five, was characterized by intense and enthusiastic discussion which reflects, we think, the exciting growth and development of this field. It is quite clear, however, that despite many general advances an understanding of the precise underlying mechanisms in B-cell tumor development is not yet defined. Probably, there is no single mechanism for all the various forms of B-cell neo plastic development. Many different forms of B-cell neoplasms are known, and these are distinguished by several characteristics: 1) the stage of development attained by the tumor stem cells; 2) mode of growth (slow or fast); 3) association with natural or inductive etiologic agents and 4) specific and consistent mutational mechanisms such as retroviral insertion, chromosomal rearrangement. Those charac teristic forms which arise naturally in relatively high frequency or those tumors with hallmark properties which can be induced consistently are the models most frequently studied, e. g. , endemic Burkitt's lymphoma, follicular lymphoma, acute and chronic lymphocytic leukemia and mUltiple myeloma in man; bursal lymphoma in chickens; Abelson virus induced pre B cell lymphomas and plasmacytomas in mice and immunocytomas in rats. Each model system, has special problems and advantages.

Book Description
This volume details our current understanding of the architecture and signaling capabilities of the B cell antigen receptor (BCR) in health and disease. The first chapters review new insights into the assembly of BCR components and their organization on the cell surface. Subsequent contributions focus on the molecular interactions that connect the BCR with major intracellular signaling pathways such as Ca2+ mobilization, membrane phospholipid metabolism, nuclear translocation of NF-kB or the activation of Bruton’s Tyrosine Kinase and MAP kinases. These elements orchestrate cytoplasmic and nuclear responses as well as cytoskeleton dynamics for antigen internalization. Furthermore, a key mechanism of how B cells remember their cognate antigen is discussed in detail. Altogether, the discoveries presented provide a better understanding of B cell biology and help to explain some B cell-mediated pathogenicities, like autoimmune phenomena or the formation of B cell tumors, while also paving the way for eventually combating these diseases.

Book Description
The eighth workshop in this series on Mechanisms in B-Cell Neoplasia 1990 was held in Wilson Hall at the National Institutes of Health, Bethesda, Maryland on March 28-30. Five major topics formed the basis for the discussions: 1) progress in experimental models of B-cell tumorigenesis, 2) the role of IL-6 in plasma cell tumor formation with particular emphasis on human myeloma, 3) immortaliza tion and regulation of mitosis in B-cells, 4) the mYQ gene in B-cell neoplasia, and 5) the role of EBV and other oncogenes in transforma tion of human B-Iymphocytes. A meeting on the Epidemiology of Myeloma was held at the N. I. H. on the preceding day, and many of those interested in the clinical aspects of myeloma were also participants at the workshop. Experimental Models of B-Cell Tumor Development We have seen in the last eight years the steady growth of model experimental systems, many of which have been designed to be counter parts of the major forms of human B cell tumors, e. g. , follicular lymphomas, Burkitt's lymphomas, acute B-cell leukemia and multiple myeloma. A variety of novel ways of inducing these tumors has been described. Advantage has been taken of the "experiments in nature" to identify critical genes that playa role in tumor pathogenesis. These genes have been identified by being near to viral insertion and chromosomal translocation sites, or by having been incorporated or transduced into a defective transforming retrovirus.

Book Description
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.

Book Description
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.

Book Description
In this volume a comprehensive review of membrane proteins that regulate complement and perforin-mediated cytolysis is presented. A detailed analysisis provided of the biochemical, molecular, and functional features of these proteins; the glycosyl phosphatidylinositol linked proteins are covered, with emphasis placed on the functional importance of this type of membrane anchor. Further chapters include reviews of the effects of complement activation on cells that are metabolically active, and of the regulation of cell killing by cytotoxic lymphocytes, considering the similarities and disparities between the complement and perforin systems. The therapeutic use of recombinant CR1 for immune-mediated pathophysiological processes is discussed in a separate section.

Book Description
Although upstaged by the tragic appearance of the human immunodeficiency virus, herpes simplex viruses (HSV) types 1 and 2 continue to be major human pathogens against which we lack acceptable vaccines or other means of immunological control. The virus is large and complex, coding for 70 or more proteins. Although many mysteries remain to be unraveled, our knowledge base regarding genomic organization, gene expression and regulation, pathogenesis, and immune recog nition of component parts is quite considerable. Indeed, meet ings devoted entirely to herpesviruses are conspicuous by their frequency and excellent, yet sometimes exclusive, attendance. The purpose of this volume is to compile in a single book a series of reviews by leading investigators that deal with various aspects of virus-host interactions and which hopefully will pro vide clues as to how to best manage HSV from an immunobio logical perspective. Ultimately, one anticipates that a full under standing of virus-host interaction will lead to strategies useful for the prevention and control of HSV. The state of current progress with conventional vaccines is presented, as is a chapter on intracellular immunization. This latter novel approach to virus infections comes at approximately the bicentenary of Jenner's introduction of a successful conventional immunization strategy.

Book Description
Shigellosis is present all over the world. Anyone traveling in developing countries knows that the control of this invasive disease of the intestine is a priority task for physicians and public health authorities. Victims are essentially young children, and complications such as the hemolytic uremic syndrome make shigellosis a systemic disease rather than simply an infection of the colonic mucosa. However, "Westerners" should not consider shigeJlosis as an unlikely threat of the tropics. The disease arises in industrialized countries as soon as breaches in sanitation appear. A few months ago, at least 500 people developed shigellosis in northern France in an outbreak of Shigella sonnei infection due to accidental contamination of an urban water delivery system. The pathogenesis of shigellosis is an extraordinary topic of research because study of the invasion of the colonic mucosa addresses fundamental questions on. the molecular and cellular mechanisms by which a bacterial pathogen can pene trate non phagocytic cells, survive, multiply, spread in the intra cellular compartment, and eventually kill host cells. Further development of the infection within subepithelial tissues as well as the mechanisms that contribute to the eradication of this process have barely been studied.
