Download Proteinase-activated Receptor-2(PAR-2) and Tumour Necrosis Factor-alpha (TNF[alpha] Signalling in Inflammation Book in PDF, ePub and Kindle
Proteinase activated receptor-2 (PAR-2) is a novel G-protein coupled receptor, that is activated by means of proteolytic cleavage (Macfarlane et al, 2001) and has both pro and anti-inflammatory actions depending upon the system examined. PAR-2 have been linked to the stress-activated protein kinases (SAPKs), JNK and p38 MAP kinase and NFK13 signalling (Kanke et al, 2001; Sabri et al, 2000), pathways known to be involved in proinflammatory responses in several cell types. TNFa has been demonstrated to up-regulate PAR-2 expression in a variety of cell types (Nystedt et al, 1996; Ritchie et al, 2007). Since both TNFa and PAR-2 are implicated in inflammation, we examined the possibility of altered PAR-2 trafficking under inflammatory conditions and possible crosstalk between PAR-2 and TNFa at the level of intracellular signalling. Previous studies have characterised P AR-2 trafficking in transfected cell lines, however the effects of inflammatory stimuli on the kinetics of PAR-2 trafficking has not been investigated. The study sought to re-characterise PAR-2 trafficking in the presence of inflammatory stimuli. NCTC2544 cells transfected with YFP epitope tagged PAR-2, demonstrated clear PAR-2 expression and trafficking of the receptor was successfully characterised, however no significant differences in the kinetics of P AR-2 trafficking under inflammatory conditions compared to control was observed. The latter part of the study examined PAR-2 and TNFa mediated activation of the MAPK and NFK13 pathways. In a keratinocyte cell line stably expressing PAR-2 (CloneG), trypsin, SLIGKV-OH, and TNFa, caused a time and concentration-dependent increase in p38 MAPK and JNK phosphorylation however, preliminary results failed to show evidence of synergy between the receptors. Surprisingly however, pre-activation of P AR-2 substantially reduced the ability of TNFa to activate JNK. The inhibitory effect of P AR-2 was mimicked by the protein kinase C activator PMA, partially reversed by the PKC inhibitor GF109203X, and completely reversed by the novel Gaqlll inhibitor YM-254890, consistent with a role for both Ca2+ -dependent and independent PKC isoforms and for P AR-2 coupling to Gaq/11 to mediate this agonist driven inhibitory response. These results indicate a potential mechanistic explanation for both the anti and pro-inflammatory actions of P AR- 2, and highlight a possible novel therapeutic avenue for the development ofPAR-2 agonists as anti-inflammatory drugs.

Download The Endothelium Book in PDF, ePub and Kindle
The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation. Table of Contents: Introduction / Multiple Functions of the Endothelial Cells / Calcium Signaling in Vascular Cells and Cell-to-Cell Communications / Endothelium-Dependent Regulation of Vascular Tone / Conclusion / References

Download Handbook of Antioxidant Methodology Book in PDF, ePub and Kindle
The field of antioxidant research has grown rapidly over the last 30 years and shows no sign of slowing down. In order to understand how antioxidants work, it is essential to understand how their activity is measured. However, antioxidant activity measurements are controversial and their value has been challenged. This book addresses a number of the controversies on antioxidant testing methods. Specifically, the book highlights the importance of context, helping the reader to decide what methods are most appropriate for different situations, how the results can be interpreted and what information may be inferred from the data. There are a multiplicity of methods for measuring activity, with no standardized method approved for in vitro or in vivo testing. In order to select an appropriate method, a thorough knowledge of the processes associated with reduction-oxidation is essential, leading to an improved understanding and use of activity measurements and the associated data. The book presents background information, in a unique style, which is designed to assist readers to grasp the fundamentals of redox processes, as well as thermodynamics and kinetics, which are essential to later chapters. Recovery and extraction of antioxidants from diverse matrices are presented in a clear and logical fashion along with methods used to determine antioxidant activity from a mechanistic perspective. Other chapters present current methodologies used for activity testing in different sample types ranging from foods and plants, to body fluids and even to packaging, but always with a strong emphasis on the nature of the sample and the underlying chemistry of the method. A number of emerging techniques for assessing antioxidant behaviour, namely, electrochemical methods, chip technology exploiting microfluidic devices, metabolomics plus studies of gene and protein expression, are examined. Ultimately, these techniques will be involved in generation of "big data" for which an understanding of chemometrics will be essential in drawing valid conclusions. The book is written to appeal to a wide audience, but will be particularly helpful for any researchers who are attempting to make sense of the vast literature and often conflicting messages on antioxidant activity.

Download Epigenetic Regulation in the Nervous System Book in PDF, ePub and Kindle
Epigenetic Regulation in the Nervous System addresses current understanding of the roles of epigenetic processes at the molecular/cellular level, their impact on neural development and behavior, and the potential roles of these mechanisms in neurological and psychiatric disorders. This award-winning volume spans molecular epigenetics, development, cellular physiology and biochemistry, synaptic and neural plasticity, and behavioral models, and is unique in covering epigenetically based disorders of the central nervous system. Behavioral epigenetics is the study of how environmental factors alter behavior, addressing the fundamental mechanisms that shape development and individual vulnerability/resilience to adverse behavioral outcomes. By understanding the molecular mechanisms involved in epigenetic modulation, researchers may be able to develop targeted therapies for those individuals in whom it malfunctions. Edited by the most highly regarded leaders in the field, this book offers a comprehensive review of behavioral epigenetics and a balanced treatment of the strengths and weaknesses in experimentation in this area. Covering background material as well as topics of current interest, it serves both as a cutting-edge resource and a foundational reference. The book will benefit neuroscience researchers and graduate students with an interest in the links between gene regulation and behavior, as will clinicians dealing with disorders such as addiction, depression, and schizophrenia.
