Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.

Book excerpt: Helper T Cells: Types, Functions and New Research presents current research in the Tfh cell research field with a special focus on the maintenance of TFH cells and their fate once the immune response has resolved. Whereas early steps of Tfh cell generation have been the subject of intense research in recent years, much less is known about signals controlling Tfh cells in late phases of the germinal center reaction and their differentiation into long-term memory cells. The authors also discuss emerging evidence that CD4+ T cells orchestrate antitumor immunity by providing critical immunological help to B cells, facilitating isotype switching and affinity maturation, and CD8+ T cells, promoting effector and memory differentiation, as well as shaping innate immunity and the tumor microenvironment. While preventing autoimmunity, selective CD4+ T-cell tolerance also compromises immunity to malignant cells that express primarily self-antigens by eliminating CD4+ T-cell help for B-cell, CD8+ T-cell, and innate immune responses. Therefore, the authors suggest that the goal of cancer immunotherapeutics should be increasingly focused on overcoming the CD4+ T-cell tolerance barrier to negate the effects of tolerance-driven immune suppression and maximize antitumor responses. Next, data is presented showing that AIT reduces the expression of CD40L glycoprotein on T CD4+ cells from patients with pollen or Hymenoptera venom allergy when were treated with specific immunotherapy compared to patients not subject to treatment. The function of CD4 T lymphocytes in the development of allergy is discussed, along with the recent results obtained about the impact of AIT on CD40L expression on T helper lymphocytes of patients.

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 233 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 Post transcriptional Control of T Follicular Helper Cells written by Alvin Pratama and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody production is a key feature of the adaptive immune response. High affinity antibodies neutralise and clear invading pathogens, thereby protecting the host against microbial infections. It is now well-established that T follicular helper (Tfh) cells - a distinct subset of CD4+ T helper cells - are essential in providing cognate help to B cells in the germinal centre (GC) to differentiate into memory and long-lived plasma cells that secrete high affinity antibodies. However, stringent control of Tfh cell numbers is crucial to produce optimally affinity-matured antibody responses that are devoid of self-reactivity. Indeed, excessive number of Tfh cells has been associated with autoimmunity. However, our understanding of the molecular mechanisms controlling Tfh cell differentiation is still incomplete. This thesis focuses on discovering novel post-transcriptional mechanisms that limit Tfh cell numbers. The data presented in this thesis show that RNA-binding proteins, Roquin and its paralogue Roquin-2, cooperate to repress Icos, a key Tfh cell molecule, and limit GC reactions. Mutations in the RING or ROQ domain of Roquin disrupted Icos mRNA regulation, but, unlike the ROQ mutant that still occupied mRNA-regulating stress granules, RING-deficient Roquin failed to localise to stress granules and allowed Roquin-2 to compensate in the repression of ICOS. In addition, the data presented here show that microRNA-146a is highly expressed in human and mouse Tfh cells and its peak expression marks the decline of the Tfh cell response. Loss of miR-146a caused cell-autonomous, spontaneous accumulation of Tfh and GC B cells. Mechanistically, miR-146a acted in both Tfh and GC B cells to control ICOS-ICOSL interactions and limit Tfh and GC B cell numbers. Collectively, Roquin family proteins and miR-146a emerge as novel post-transcriptional brakes on ICOS expression, thus limiting Tfh cell numbers and GC responses.

Download or read book Transcription Factor Regulation of T Helper Subset Function written by Olufolakemi O. Awe and published by . This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immune system protects the body from foreign organisms. T cells and B cells are integral components of the ability of the immune system to generate focused immune responses. The development of specialized subsets of T helper cells is governed by transcription factors. Previous work demonstrated a requirement for the transcription factor PU. 1 in the development of IL-9-secreting Th9 cells. Work in this dissertation demonstrates that the Th9 subset is not stable in vitro, and that PU. 1 expression decreases during long-term culture. To examine a role for PU. 1 in Th9-independent immunity we examined a model of multiple sclerosis termed experimental autoimmune encephalomyelitis (EAE). Mice that lack PU. 1 expression in T cells (Sfpi1lck-/- mice) demonstrated more severe disease with attenuated recovery compared to control mice, and this was accompanied by an increase of T cells in the central nervous system. We also observed that following multiple routes of immunization Sfpi1lck-/- mice had increased numbers of T follicular helper (Tfh) cells and increased germinal center responses. This correlated with increased expression of the cytokine IL-21 and the surface protein CD40L in T cells that lacked PU. 1 expression and resulted in increased numbers of germinal center B cells and antigen-specific antibody titers compared to control mice. The increased germinal center B cells and antibody titers were attenuated with blocking CD40L antibody but not with neutralizing IL-21 antibody. These results suggest that PU. 1 limits the expression of CD40L on Tfh cells to regulate the humoral immune response. Together, the data in this dissertation demonstrate Th9-independent functions of PU. 1. Moreover, this work shows that transcription factors promoting the development of one subset of T helper cells can simultaneously have negative effects on distinct T cell lineages.

Download or read book CD4 CD25 Regulatory T Cells Origin Function and Therapeutic Potential written by B. Kyewski and published by Springer Science & Business Media. This book was released on 2006-01-09 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate immune system defends the organism against invading pathogens while at the same time being self-tolerant to the body’s own constituents thus preserving its integrity. Multiple mechanisms work in concert to ensure self-tolerance. Apart from purging the T cell repertoire from auto-reactive T cells via negative selection in the thymus dominant tolerance exerted by regulatory T cells plays a major role in tolerance imposition and maintenance. Among the various regulatory/suppressive cells hitherto described, CD4+CD25+ regulatory T cells (Treg) and interleukin-10 producing T regulatory 1 (Tr1) cells have been studied in most detail and are the subject of most articles in this issue. Treg, also called "natural" regulatory T cells, will be traced from their intra-thymic origin to the site of their action in peripheral lymphoid organs and tissues. The repertoire of Treg is clearly biased towards recognition of self-antigens, thereby potentially preventing autoimmune diseases such as gastritis and oophoritis. Regulatory T cells, however also control infections, allergies and tolerance to transplanted tissues and this requires their induction in the periphery under conditions which are not yet fully understood. The concept of dominant tolerance, by far not novel, will offer new insights and hopefully tools for the successful treatment of autoimmune diseases, improved cancer immunotherapy and transplant survival. The fulfillment of these high expectations will, however, require their unambiguous identification and a better understanding of their mode of action.
