Available in PDF, EPUB and Kindle. Book excerpt: B cell development is severely impaired in the absence of SLP65 adaptor protein. SLP65-deficient B cells are arrested at the large cycling pre-B cell stage in the bone marrow and transitional B cell stages in the spleen of mice. The zinc-finger transcription factor EGR1 is an immediate early gene induced upon Ag-binding and BCR engagement in B cells. EGR1 promotes B cell differentiation and maturation at the progression from pro-B to pre-B and into the mature B cell stages. The main hypothesis of this study was that EGR1 expression is regulated through a SLP65-dependent signaling chain and therefore, EGR1 overexpression in SLP65-/- mice could restore or at least partially rescue developmental blocks caused by the absence of SLP65 in B cells. The results revealed that both EGRxSLP65-/- and SLP65-/- B cells appear to be arrested at the same developmental (large pre-B cell) stage, suggesting that in the absence of SLP65, EGR1 activity alone is not sufficient to rescue the developmental block in the bone marrow. However, independent of this developmental arrest EGR1 overexpression mediates downregulation of IL-2R alpha chain in B cells. Further analysis showed that although EGR1 could not completely rescue the developmental arrest at the transitional B cells stages in EGRxSLP65-/- mice, splenic B cells from EGRxSLP65-/- mice have a more mature phenotype compared to splenic B cells from SLP65-/- animals. In order to determine the underlying molecular basis of these EGR1-mediated phenotypic changes in EGRxSLP65-/- B cells as well as to identify additional EGR1 target genes in B cells, gene expression profiling experiments were performed. By microarray hybridizations and several validation methods at least nine genes were found to be differentially regulated in EGRxSLP65-/- B cells. Inspection of the promoter sequences suggests that seven genes: Ly-6A/E, TAF10, SLFN1, SLFN2, CalA, CCR2 and Oct1 might be potential EGR1 target genes in B cells. Ly-6D and Ly-6E are upregulate.

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.

Download or read book T Cell Protocols written by Kelly P. Kearse and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of T Cell Protocols: Development and Activation is to c- lect a series of protocols, particularly those that have been developed within the past few years, to help investigators master new techniques (or improve existing ones) for the study of T-cell Biology. Invariably, in putting together a book like this it is difficult to decide which methods to include and which to leave out. To this end methods were selected from a variety of disciplines, including cellular immunology, b- chemistry, and molecular biology, to try to provide something of interest for everyone who works on T-cell development and activation. I would like to mention that my primary reason for agreeing to put this book together is that, when I was a graduate student, I purchased a copy of Selected Methods in Cellular Immunology by Mishell and Shigii which proved a tremendous help in learning the basics of one-and two- dimensional gel te- niques (and other methods). The cover has long since fallen off, but it still remains one of my most valued reference books for the laboratory. It is my hope that T Cell Protocols: Development and Activation will prove similarly useful to current and future scientists wishing to learn new methods for expl- ing the development and activation of T cells.

Available in PDF, EPUB and Kindle. Book excerpt: B cells used to be considered as a homogeneous population of cells destined to produce antibodies of increasing affinity and to maintain an immunological memory. In recent years, it has been determined that B cells can be subdivided into different subsets characterized by distinct morphologic, phenotypic, and functional features. Presenting results of research work on the definition of B cell subset populations, this book explains the basic mechanisms that control B cell activation, stimulation and regulation. Articles include studies on both normal and malignant B cells and describe the mechanisms underlying T-B cell interactions during the immune response. The most important advances in the field of immunodeficiency are also reported. This volume will be essential not only for basic and clinical immunologists, but also for hematologists, pathologists and rheumatologists with a special interest in the pathogenesis of lymphoproliferative or autoimmune disorders.

Available in PDF, EPUB and Kindle. Book excerpt: “Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.
