Available in PDF, EPUB and Kindle. Book excerpt: The early B cell response to antigen is analyzed, probing the mechanisms of divergent differentiation into plasmablasts or germinal centre (GC) B cells. Heterozygous QMxB6 mice, in which 5% of B cells are specific for the hapten 4-hydroxy-3-nitrophenol (NP), were immunized with NP-Ficoll. Varying the antigen dose altered the proportion of B cells that entered the extra follicular or GC responses and the amount of class switch recombination (CSR). The expression of phenotypic markers and switched antibody protein in parallel with gene array analysis and single cell real time RT-PCR in responding B cells was used to identify GC and plasmablast precursors and when and where CSR occurred. The results suggest CSR occurs in B blasts before GC B cells or plasmablasts emerge in both thymus dependent and thymus independent type II responses. The protein IRF4, which is essential for CSR and plasmablast differentiation, is expressed in all responding cells immediately after immunization and selectively upregulated to high levels in plasmablasts. A hierarchy of gene expression was identified as B cells differentiate into plasmablasts whereby high IRF4 mRNA expression precedes CD138 protein, which in turn precedes Blimp1 expression.

Download or read book Chimpanzees in Biomedical and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2011-12-05 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, experiments using chimpanzees have been instrumental in advancing scientific knowledge and have led to new medicines to prevent life-threatening and debilitating diseases. However, recent advances in alternate research tools have rendered chimpanzees largely unnecessary as research subjects. The Institute of Medicine, in collaboration with the National Research Council, conducted an in-depth analysis of the scientific necessity for chimpanzees in NIH-funded biomedical and behavioral research. The committee concludes that while the chimpanzee has been a valuable animal model in the past, most current biomedical research use of chimpanzees is not necessary, though noted that it is impossible to predict whether research on emerging or new diseases may necessitate chimpanzees in the future.

Download or read book B Cell Receptor Signaling written by Tomohiro Kurosaki and published by Springer. This book was released on 2015-12-26 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Animal models of autoimmunity are also covered, and the up-to-date account provided in this book explains how natural autoantibodies have important regulatory functions and also occasionally serve as templates for autoimmunity. Other topics examined in Natural Autoantibodies: Their Physiological Role and Regulatory Significance include idiotypes of natural autoantibodies; the pathogenic role of natural autoantibodies; and methods to measure the effects of genetic and sex hormones, as well as aging, on natural autoantibodies. The book will be an excellent research tool and reference for immunologists, rheumatologists, and others interested in the topic.
Download or read book Vaccines for the 21st Century written by Institute of Medicine and published by National Academies Press. This book was released on 2001-02-21 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vaccines have made it possible to eradicate the scourge of smallpox, promise the same for polio, and have profoundly reduced the threat posed by other diseases such as whooping cough, measles, and meningitis. What is next? There are many pathogens, autoimmune diseases, and cancers that may be promising targets for vaccine research and development. This volume provides an analytic framework and quantitative model for evaluating disease conditions that can be applied by those setting priorities for vaccine development over the coming decades. The committee describes an approach for comparing potential new vaccines based on their impact on morbidity and mortality and on the costs of both health care and vaccine development. The book examines: Lessons to be learned from the polio experience. Scientific advances that set the stage for new vaccines. Factors that affect how vaccines are used in the population. Value judgments and ethical questions raised by comparison of health needs and benefits. The committee provides a way to compare different forms of illness and set vaccine priorities without assigning a monetary value to lives. Their recommendations will be important to anyone involved in science policy and public health planning: policymakers, regulators, health care providers, vaccine manufacturers, and researchers.

Download or read book The Epstein Barr Virus written by M. A. Epstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Epstein-Barr virus was discovered 15 years ago. Since that time an immense body of information has been accumu lated on this agent which has come to assume great signifi cance in many different fields of biological science. Thus, the virus has very special relevance in human medicine and oncology, in tumor virology, in immunology, and in mole cular virology, since it is the cause of infectious mononu cleosis and also the first human cancer virus, etiologically related to endemic Burkitt's lymphoma and probably to nasopharyngeal carcinoma. In addition, continuous human lymphoid cell lines initiated and maintained by the transform ing function of the virus genome provide a laboratory tool with wide and ever-growing applications. Innumerable papers on the Epstein-Barr virus have ap peared over recent years and reports of work with this agent now constitute a veritable flood. The present book provides the first and only comprehensive, authoritative over-view of all aspects of the virus by authors who have been the original and major contributors in their particular disciplines. A complete and up-to-date survey of this unique and important agent is thus provided which should be of great interest to experts, teachers, and students engaged in cancer research, virology, immunology, molecular biology, epide miology, and cell culture. Where topics have been dealt with from more than one of these viewpoints, some inevitable overlap and duplication has resulted; although this has been kept to a minimum, it has been retained in some places because of positive usefulness.
