Available in PDF, EPUB and Kindle. Book excerpt: The relationship between resources and development is the pivot around which the present study revolves. Focussing on the process of resource creation and utilization it emphasizes the need of equitable development integrating local needs, resources, people and functions. The resource exploitation and their utilization are two independent economic activities influenced by different algorithms and usually have manifested in core-periphery relationship. Reviews the persistent problems of economic development in perspective of exploitation of natural resources with the objective to provide some clues for occurrence and persistence of regional disparities and for suggesting a development model synchronising both the resource management and environmental protection.

Download or read book The nature of activatory and tolerogenic dendritic cell derived signal 2 written by Francesca Granucci and published by Frontiers E-books. This book was released on 2014-07-08 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most interesting issues in immunology is how the innate and adaptive branches of the immune system cooperate in vertebrate organisms to respond and destroy invading microorganisms without destroying self-tissues. More than 20 years ago, Charles Janeway proposed the innate immune recognition theory [1]. He hypothesized the existence of innate receptors (Pattern recognition receptors, PRRs) that, by recognizing molecular structures associated to pathogens (PAMPs) and being expressed by antigen presenting cells (APCs) and epithelial cells, could alert the immune system to the presence of a pathogen, making it possible to mount an immediate inflammatory response. Moreover, by transducing the alert signal in professional APCs and inducing the expression of costimulatory molecules, these receptors could control the activation of lymphocytes bearing clonal antigen-specific receptors, thereby promoting appropriate adaptive immune responses. Since adaptive immunity can be activated also following sterile inflammatory conditions, it was subsequently proposed by Polly Matzinger that the innate immune system could be also activated by endogenous danger signals, generically called danger associated molecular patterns (DAMPs)[2]. The first prediction has been amply confirmed by the discovery of Toll-like receptors [3; 4; 5] and cytoplasmic PRRs such as RIG-like receptors [6]. Other PRR families such as the NOD-like receptors and C-type lectins exert immunogenic or tolerogenic signals [7; 8; 9] and may recognize not strictly pathogens but also endogenous danger signals that may lead to inflammasome activation [10; 11] . Dendritic cells (DCs) have been identified as the cells of the innate immune system that, by sensing PAMPs or DAMPs transduce signals to the nucleus. This leads to a transcriptional reprogramming of DCs with the consequent expression of three signals, namely signal 1 (MHC+peptide), signal 2 (surface costimulatory molecules) and signal 3 (cytokines) necessary for the priming of antigen-specific naïve T cell responses (signal 1 and 2) and T cell polarization (signal 3). The reason why DCs are superior with respect to other professional APCs in naïve T cell activation has not been unequivocally defined but in vivo may mainly result from their migration capacity to secondary lymphoid organs. It has not been established whether DCs can provide a special “signal 2” or simply very high levels, compared with other APCs, of commonly expressed signals 1 and 2, so that a naïve T cell could reach the threshold of activation. A second aspect of DC biology needs also to be taken into account. Concerning the question of how self-tissues are not destroyed following the initiation of adaptive immune responses, different mechanisms of central and peripheral auto-reactive T cell tolerization have been proposed [12]. In particular, it has been defined that high affinity T cells are deleted in the thymus, while low affinity auto-reactive T cells or T cells specific for tissue-sequestered antigens that do not have access to the thymus are controlled in the periphery. In a simplified vision of how peripheral T cell tolerance could be induced and maintained, it was thought that, in resting conditions, immature DCs, expressing low levels of signal 1 and low or no levels of signal 2, were able to induce T cell unresponsiveness. Nevertheless, it is now clear that a fundamental contribution to the peripheral tolerance is due to the conversion of naïve T cells into peripheral regulatory T cells (pTreg cells) and it is also clear that DCs need to receive a specific conditioning to become able to induce pTreg cell differentiation. Even more intriguing is that also DCs activated through PRRs, with particular Toll like receptor (TLR) agonists, are capable of generating pTreg cell conversion if these agonists induce the production of the appropriate cytokines.

Download or read book Stem Cell Therapy for Autoimmune Disease written by Richard K. Burt and published by CRC Press. This book was released on 2019-11-11 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem cell transplantation may be complicated by treatment-related mortality and like the immune system that it regenerates has equal potential to either create and preserve or destroy. The dual nature that defines stem cells is differentiation that ultimately leads to death and self-renewal, which leads to immortality. What types of stem cells are there? How are they collected? What are their attributes and characteristics? This textbook devotes many chapters to familiarize the reader with the basic science, clinical aspects, and new questions being raised in the field of stem cell biology. Blood stem cells for tolerance and tissue regeneration are a rapidly developing research and clinical field that is being applied to autoimmune diseases. In clinical trials, autologous hematopoietic (blood) stem cells are being used to reduce the cytopenic interval following intense immune suppressive transplant regimens. While as yet not delineated, some possible mechanisms and pathways leading to tolerance after hematopoietic stem cell transplantation are suggested in these chapters. Tissue regeneration from blood stem cells is also suggested by animal experiments on stem cell plasticity or metamoirosis (i.e., change in fate) as described within this textbook. Ongoing early clinical trials on tissue regeneration from blood stem cells are described in the chapter on stem cell therapy for cardiac and peripheral vascular disease. Whether autologous hematopoietic stem cells, through the process of mobilization and reinfusion, may be manipulated to contribute to tissue repair in autoimmune diseases is a future area for translational research.

Download or read book Intradermal Immunization written by Marcel B.M. Teunissen and published by Springer Science & Business Media. This book was released on 2011-09-15 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Current Topics in Microbiology and Immunology covers diverse topics related to intradermal immunization. The chapters highlight the effectiveness of intradermal immunization in experimental animal models or in clinical practice, all supporting the view that intradermal immunization is at least as good as other immunization routes. Keeping in mind that current vaccines are not specially designed for intradermal immunization, but show comparable efficiency even at reduced dosages, this underlines the great potential for the skin as a vaccination site. Hopefully, the overview in this volume will encourage vaccine designers to focus on this promising immunization route, and in addition, to inspire them to develop vaccines that are especially optimized for intradermal immunization.

Download or read book Coping With Extreme Environments A Physiological Psychological Approach written by Costantino Balestra and published by Frontiers Media SA. This book was released on 2019-06-25 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how humans cope in extreme environments has expanded our knowledge of the physiological and psychological challenges involved and helped us to quit our comfortable paradigms built on “steady states”. Furthermore, measuring our reactions to intermittent stressors and determining the oscillations of our coping mechanisms has led us to unexpected understandings. This methodology has also directly improved our translational or multidisciplinary approach to the subject. Studying healthy individuals in extreme environments could improve our understanding of patients with impaired physiological capacities (who are coping with an environment that becomes extreme to them) and also improve our understanding of physiology and psychology in the elderly.This eBook collects articles that address this translational multidisciplinary approach in an integrative way. As a whole, this Research Topic aims to better understand human/animal physiology and psychology.

Download or read book Cytokines and Colony Stimulating Factors written by Dieter Körholz and published by Springer Science & Business Media. This book was released on 2008-02-04 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immune system is a complex network in which different cell types and soluble factors interact to efficiently eliminate various kinds of microorganisms as well as aberrant cell clones. The roots of immunologic investigations reach far into the past. In 430 BC, Thucydides reported that survivors of the plague did not present a second time with similar symptoms. The first report of a successful immu- therapy was made by Edward Jenner in 1798 who found a protective effect of cowpox vaccination against human pox. Since then, much knowledge has been accumulated; today, investigations of the molecular mechanisms of immune regulation are of central research interest. The novel insights into gene polymorphisms and gene regulation gathered from this work has improved our knowledge of individual immune reactions and risk factors in overcoming infections. Strategies to use the immune system for cancer treatment have been propelled by the discovery of divergent immunoregulatory cytokines and the introduction of new gene therapy strategies to modify immune responses. Recently, the discovery of various dendritic cells has focused attention on these cell types as central elements of the immune response and to the possibility of dendritic cell expansion, maturation, and consecutive stimulation with immuno- active tumor-specific peptides. Similarly, methods for ex vivo expansion of various stem cell-derived cell types have led to an improved therapeutic management of various benign and malignant diseases.

Download or read book Innate Immunity Resistance and Disease Promoting Principles written by G. Hartmann and published by Karger Medical and Scientific Publishers. This book was released on 2013-06-05 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the complex innate immune response is increasing rapidly. Its role in the protection against viral or bacterial pathogens is essential for the survival of an organism. However, it is equally important to avoid unregulated inflammation because innate immune responses can cause or promote chronic autoinflammatory diseases such as gout, atherosclerosis, type 2 diabetes or certain aspects of the metabolic syndrome. In this book leading international experts in the field of innate immunity share their findings, define the ‚state of the art‘ in this field and evaluate how insight into the molecular basis of these diseases could help in the design of new therapies. A tremendous amount of work on the innate immune response has been done over the last fifteen years, culminating in the 2011 Nobel Prize in Physiology/Medicine awarded for the discoveries of Toll genes in immunity in flies, membrane-bound Toll-like receptors in mammals, and dendritic cells as initiators of adaptive immunity.
