This book was released on 2012-12-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original series, Advances in Prostaglandin Research, edited by Sultan M. M. Karim, was published by MTP Press in three volumes in 1975 and 1976. A glance at those books illustrates the progress that has been made since then. The thromboxanes were mentioned twice (first publication 1975) and prostacyclin not once (first publication 1976); leukotrienes were only on the horizon. The amazing generation of research data in the last 10-15 years has given new, broad insights into many areas, including asthma, inflammation, renal, cardiovascular and gastrointestinal diseases and in reproduction, and has led in some instances to real clinical benefit. This series, Advances in Eicosanoid Research, reflects the current understanding of prostaglandins, thromboxanes and leukotrienes. The aim is to provide an introductory background to each topic and the most up-to-date information available. Although each book stands alone, the eicosanoids cut across many boundaries in their basic actions; selected chapters from each book in the series will provide illuminating and productive information for all readers which will advance their education and research. In the production of this series, I must acknowledge with pleasure my collaboration with editors and authors and the patient endeavours of Dr Michael Brewis and the staff at MTP Press.

Available in PDF, EPUB and Kindle. Book excerpt: Fatty acids play an important role in the barrier function of skin and represent a major source of proinflammatory mediators such as prostaglandins, leukotrienes and other lipids in inflammatory skin disorders. This book combines the two major functions of fatty acids in skin biology. In the first part the biosynthesis of fatty acids in skin with its role in barrier function as well as the role of dietary fatty acids on skin cell function and in the treatment of inflammatory skin diseases is presented. The second part deals with skin as a source of proinflammatory eicosanoids, especially with the keratinocyte as a major cellular source. Metabolism of eicosanoids in skin, its role in psoriasis and atopic dermatitis as well as pharmacological inhibition of eicosanoid biosynthesis is reviewed. The book finishes with a chapter describing the methods used for quantification of fatty acids and derivatives in skin inflammation. Anyone interested in skin physiology would benefit from the overviews about the two sites of fatty acids' function in skin integrity and in skin inflammation.

Download or read book New Trends in Allergy III written by Johannes Ring and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international symposium "New Trends in Allergy", held in Munich from July 13 to 15, 1990, brought together for the third time since 1980 some of the most experienced researchers working in the field of allergy. This volume comprises the papers presented at this meeting. All over the world, and not merely in the industrialized countries, allergy is becoming a cause of evermore serious diseases. In recent years, research in the field of allergy has provided numerous impor tant and fascinating results extending our knowledge considerably. Despite the new insights into basic mechanisms of allergic reactions, improved diagnostic methods, and new therapeutic approaches, how ever, many questions remain to be answered, including: Are allergies really increasing in frequency? If so, what are the reasons? Especially, does environmental pollution playa role? Which factors influence IgE synthesis? Can the IgE immune response be switched off? Does the nervous system interact with allergic reactions? If so, what are the mechanisms? Are new approaches in allergy prophylaxis and allergy therapy effi cient? What measures have proven useful and deserve to be employed in daily practice? In this volume, these questions and other current topics are dealt with. As each issue is covered by authors competent in the respective fields, the result is an extensive and critical review of the state of the art. Going through these papers, one comes to the conviction that allergy research is a multifacetted, explosively expanding, most stimulating field of work.

Download or read book The Role of Eicosanoids in the Human Skin s Response to Ultraviolet Radiation written by Karl Gledhill and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Erythema is a hallmark skin response to excessive ultraviolet radiation (UVR) and is associated with cutaneous inflammation. Both are mediated by inflammatory mediators including nitric oxide (NO), prostaglandin E2 (PGE2) and chemoattractants such as 12-hydroxyeicosatetraenoic acid (12-HETE) leading to vasodilation and increased leukocyte infiltration. The erythematous response is more pronounced in individuals with low basal melanin levels or who fail to respond to UVR with a robust up-regulation of melanogenesis. While melanin production is a key function of melanocytes, these cells can also produce NO and PGE2, and are located in close proximity to the dermal vasculature. It has been hypothesized that melanocytes with poor melanogenic capacity may participate in the inflammatory response to UVR. The aim of this project was to investigate the inflammatory response in the skin of individuals with either skin phototype (SPT) 1 or 4 to UVR. Sixteen normal healthy individuals were selected for study (8 SPT-1 & 8 SPT-4). Buttock skin was investigated by immunohistochemistry for leukocyte subtypes, eicosanoid producing enzymes and NO synthases under basal and UVR-stimulated conditions. In addition primary cultures of epidermal melanocytes (EM) were established from 16 individuals (8 SPT-1 & 8 SPT-4) and assessed for the presence of eicosanoid-producing enzymes, melanogenic enzymes and NO synthases, by immunocytochemistry, Polymerase Chain Reaction and Western Blotting and for the production of the main pro-inflammatory eicosanoid PGE2 by ELISA and Mass Spectrometry. Moreover, the fatty acid composition of cultured melanocytes was assessed by Gas Chromatography. Results showed that individuals with SPT-1 had significantly greater neutrophil infiltration into the epidermis than those with SPT-4 at 24 hrs post-UVR. Moreover, CD3+ lymphocyte infiltration into the dermis was significantly greater in individuals with SPT-4 than those with SPT-1 at 24 and 72 hrs post-UVR. NOS-1, NOS-3, 12-LOX and COX-2 expression were significantly increased in SPT-1 skin, while NOS-2 and 15-LOX were significantly increased in SPT-4 skin. As 12-LOX and COX-2 products are chemoattractive (for neutrophils) and pro-inflammatory respectively these data could explain the greater observed neutrophil infiltration in SPT-1. The 15-LOX product (15-HETE) is anti-inflammatory and may suggest that 15-LOX up-regulation in SPT-4 skin may aid resolution of the sunburn response, which in part may be mediated by CD3+ lymphocytes and a class-switch in eicosanoid production from COX to LOX products. Melanocyte primary cultures surprisingly showed that SPT was not correlated with melanin content or melanogenic enzyme expression/activity suggesting that all melanocytes in vitro contained the necessary cellular machinery to produce melanin. This finding may reflect also their equal treatment under these enriched culture conditions, which may or may not be available to these cells in situ. Moreover, all melanocytes expressed the necessary machinery (PLA2, COX-1, cPGES) to produce PGE2. However, only some cultures did so at baseline and in response to UVR, and this was not correlated with SPT. A positive correlation was found however between expression level of dopachrome tautomerase (DCT) and protection against PGE2 production in response to UVR, which may suggest a novel role for DCT unrelated to melanogenesis. In summary this research project has generated data that highlights differences between the skin of individuals with SPT-1 and those with SPT-4, and may provide evidence that the keratinocyte partner contributes significantly to the SPT-associated response. This research may also suggest DCT as a novel therapeutic target to protect EM from participation in the UVR-associated inflammatory response in skin.

Book excerpt: This volume represents a collection of contributions from the 6th International Conference on Eicosanoids and Other Bioactive Lipids in Cancer, Inflammation, and Related Diseases held in Boston from September 12-15, 1999. The mission of this meeting was to bring together senior and junior investigators to both announce and examine their recent advancements in cutting-edge research on the roles and actions of lipid mediators and their impact in human physiology and disease pathogenesis. The meeting focused on new concepts in these areas of interest to both clinicians and researchers. The program included several outstanding plenary lectures and presentations by leading experts in the fields of cancer and inflammation. In addition, the Boston meeting presented three Young Investigator awards, one in each of the major focus areas. The meeting was exciting and proved to be very memorable. The program was developed with an emphasis on recent advances in molecular and of lipid mediators relevant in cellular mechanisims involved in the formation and actions inflammation and cancer. Plenary lectures were presented by Prof. Bengt Sammuelsson (Karolinska Institute, Stockholm; 1982 Nobel Laureate in Physiology or Medicine) and Prof. E. 1. Corey (Harvard University; 1990 Nobel Laureate in Chemistry). Both of these plenary lectures were held on Day 1, which set an exciting tone for this meeting. Immediately following these plenary lectures, three simultaneous breakout sessions were held, one of inflammation, a second on cancer and synthesis of novel inhibitors, and a third on enzymes-lipoxygenases/cyclooxygenases and inhibitors.

Download or read book Eicosanoids in Invertebrate Signal Transduction Systems written by David W. Stanley and published by Princeton University Press. This book was released on 2014-07-14 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume generates a new paradigm for researching and understanding the biological meaning of eicosanoids. Eicosanoid is a general term for oxygenated metabolites of certain polyunsaturated fatty acids. The compounds are extremely important in human biology, in which they are well understood. Their importance to humans, however, has tended to overshadow their broader biological significance. David Stanley seeks to change that in this book, providing a general sketch of the medical background on eicosanoids and then developing a detailed critical treatment of eicosanoid actions in invertebrates and some lower vertebrates. Stanley looks at the role of eicosanoids in, for example, invertebrate reproduction, immunity, and ion transport physiology. As he explains, eicosanoids also mediate important ecological interactions, particularly host-parasite interactions. Drawing on these physiological and ecological actions, the book develops a "biological paradigm," under which we understand that eicosanoids probably exert important actions in most, if not all, animals. Because eicosanoids mediate crucial events in the lives of animals, they are endowed with unusual explanatory power. Research designed to increase our understanding of eicosanoids has thus yielded and will continue to yield important new information about animal biology. In addition to representing a major advance in our understanding of eicosanoids in animals, this book serves as an unusually comprehensive and accessible introduction to eicosanoid research in general.

Download or read book Eicosanoids and Radiation written by Peter Polgar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prostaglandins, Leukotrienes, and Cancer is a multi-volume series that will focus on an emerging area of cancer research. In 1968, R.H. Williams first reported that elevated prostaglandin levels are present in human medullary car cinoma. Since that time, the concept that arachidonic acid metabolites may be in volved in cancer has expanded to include every aspect of the disease from cell transformation through metastasis. Prostaglandins and leukotrienes are generic terms used to describe a family of bioactive lipids produced from unsaturated fatty acids (principally from arachidonic acid) via the cyclooxygenase and lipoxygenase pathways, respec tively. Cyclooxygenase products consist of diverse products such as prosta glandin Ez (PGEz), prostacyclin (PGIz) and thromboxane Az (TXAz), whereas lipoxygenase products consist of hydroperoxy fatty acids and mono-, di- and tri-hydroxy acids including leukotrienes. The precursor fatty acids for the cyclooxygenase and lipoxygenase pathways are present in cellular phospholipids. This finding established an important control point in their biosynthesis-the release of substrate. This occurs in response to numerous stimuli that act at the cell surface. Dr. Bengt Samuelsson's extensive study of the metabolism of pros taglandins indicated that they are rapidly inactivated on a single pass through pulmonary circulation. Thus, they cannot act as circulating hormones and appear to be made on demand in or in the vicinity of target tissues leading to the concept that prostaglandins are local hormones or autocoids.
