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.
Download or read book The Impact of Food Bioactives on Health written by Kitty Verhoeckx and published by Springer. This book was released on 2015-04-29 with total page 341 pages. 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.

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 Understanding Pathogenic and Physiological T Follicular Helper Cell Formation written by Candice Sau Kuen Lee and published by . This book was released on 2012 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: T follicular helper (Tfh) cells localize to follicles where they provide growth and selection signals to mutated germinal center (GC) B cells, thus promoting their differentiation into high affinity long-lived plasma cells and memory B cells. T-dependent B cell differentiation also occurs extrafollicularly, giving rise to unmutated plasma cells that are important for early protection against microbial infections. Bcl-6 expression in T cells has been shown to be essential for the formation of Tfh cells and GC B cells, but little is known about its requirement in physiological extrafollicular antibody responses. We use several mouse models in which extrafollicular plasma cells can be unequivocally distinguished from those of GC origin, combined with antigen-specific T and B cells, to show that the absence of T cell-expressed Bcl-6 significantly reduces T-dependent extrafollicular antibody responses. Bcl-6+ T cells appear at the T-B border soon after T cell priming and before GC formation, and these cells express low amounts of PD-1. Their appearance precedes that of Bcl-6+PD-1hi T cells, which are found within GC. IL-21 acts early to promote both follicular and extrafollicular antibody responses. In conclusion, Bcl6+ T cells are necessary at B cell priming in order to form extrafollicular antibody responses, and these pre-GC Tfh cells can be distinguished phenotypically from GC Tfh cells. Overactivity of the GC pathway due to accumulation of Tfh cells causes autoimmunity, underscoring the need to understand the factors that control Tfh homeostasis. Here, we have identified posttranscriptional repression of interferon-gamma (Ifng) mRNA as a novel mechanism to limit Tfh cell formation. Using the sanroque lupus model, we have shown that decreased Ifng mRNA decay caused excessive interferon-gamma signaling in T cells and led to accumulation of Tfh cells, spontaneous GC, autoantibody formation and nephritis. Unlike ICOS and T-bet deficiency that failed to rescue several autoimmune manifestations, interferon-gamma receptor deficiency completely prevented lupus development. Interferon-gamma blockade after disease onset reduced Tfh cells and autoantibodies, demonstrating that interferon-gamma overproduction was required to sustain lupus-associated pathology. Increased interferon-gamma signaling caused Bcl-6 overexpression in Tfh cells and their precursors. This novel link between interferon-gamma and aberrant Tfh formation provides a rationale for interferon-gamma blockade in lupus patients with an overactive Tfh cell-associated pathway.
