Available in PDF, EPUB and Kindle. Book excerpt: Asthma is an inflammatory disease of the airways characterised by airway remodelling and hyperresponsiveness. New treatments are needed for patients with severe asthma whose disease is not controlled with currently available therapies. Asthma pathophysiology is complex, however, accumulating evidence suggests multiple inflammatory pathways in asthma converge onto a relatively small number of downstream targets that may be of therapeutic interest. These include mitogen activated protein kinases (MAPKs), the pro-inflammatory transcription factors nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) and transcriptional regulators such as histone acetyl transferases (HATs) and histone deacetylases (HDACs). Chemokines are molecules secreted at sties of inflammation, attracting inflammatory cells and perpetuating the inflammatory response. Here we studied the mechanisms by which the pro-inflammatory mediator endothelin-1 (ET-1) and the cytokine tumour necrosis factor-alpha (TNF-alpha) promoted expression by primary human airway smooth muscle cells (HASMC) of two important chemokines, monocyte chemotactic protein-1 (MCP-1) and eotaxin. Further, we studied the mechanisms by which existing asthma therapies (long acting beta agonists (LABA) and glucocorticoids) modulated TNF-alpha-stimulated eotaxin expression. Endothelin-1 stimulated MCP-1 release through a transcriptional mechanism involving NF-kappaB and AP-1; the upstream signalling pathway involved p38 and p44/p42 MAPKs. Previously, this lab showed that TNF-alpha-induced eotaxin release is also NF-kappaB-dependent, involving histone H4 acetylation at the eotaxin promoter. Here we found that TNF-alpha-induced eotaxin release does not involve histone H3 acetylation, and that TNF-alpha-dependent histone H4 acetylation does not occur through alterations in total histone activity or levels of the key HDACs -1 and -2. Similarly, modulation of TNF-alpha effects on eotaxin expression by glucocorticoids and LABA is independent of total HDAC activity and HDAC-1 and -2 levels. These studies support the body of evidence suggesting that multiple inflammatory pathways in asthma converge onto a small number of downstream targets, and are relevant to the understanding and treatment of asthma.

This book was released on 2007 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Collectively, our results demonstrate the expression of functional C-C chemokine receptors by ASMC. Interestingly, we have shown that CCR3 activation mediates ASMC migration and provides a new possible mechanism for the increased smooth muscle mass observed in asthmatic patients. Although the exact function of the CCR1 expressed by ASMC is unknown, our results suggest an involvement in asthma pathogenesis, possibly through airway remodelling." --

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Chemokine Research Trends written by Leah R. Grinwald and published by Nova Publishers. This book was released on 2007 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemokines are the cytokines that may activate or chemoattract leukocytes. Each chemokine contains 65-120 amino acids, with molecular weight of 8-10 kD. Their receptors belong to G-protein-coupled receptors. Inflammatory chemokines are released from a wide variety of cells in response to bacterial infection, viruses and agents that cause physical damage such as silica or the urate crystals that occur in gout. They function mainly as chemoattractants for leukocytes, recruiting monocytes, neutrophils and other effector cells from the blood to sites of infection or damage. They can be released by many different cell types and serve to guide cells involved in innate immunity and also the lymphocytes of the adaptive immune system. The cells that are attracted by chemokines follow a signal of increasing chemokine concentration to the site of infection or tissue injury. Some chemokines also have roles in the development of lymphocytes, migration and angiogenesis (the growth of new blood vessels).Since the entry of HIV into host cells requires chemokine receptors, their antagonists are being developed to treat AIDS.

Download or read book T Cell Regulation in Allergy Asthma and Atopic Skin Diseases written by Kurt Blaser and published by Karger Medical and Scientific Publishers. This book was released on 2008-01-01 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of the art in cellular and molecular mechanisms regulating the immune response in allergic inflammation. Special attention is given to the central role of regulatory T cells (Treg) in immune regulation and induction of peripheral tolerance, as well as to the relevance of Th17 cells in chronic inflammation. The importance of Treg and Th17 cells is demonstrated in bronchial asthma, atopic eczema, contact dermatitis and delayed-type hypersensitivity. Furthermore, T-cell-mediated regulatory mechanisms in helminthic infections and fungal allergy are discussed. Several chapters are devoted to the therapeutic consequences that these recently discovered T-cell functions may have. Their role as a potential target for specific immunotherapy is evaluated and novel approaches for peripheral tolerance induction and treatment of allergic and asthmatic diseases and inflammation are suggested. Stem cell transplantation as a future therapeutic intervention in regulatory T-cell disorders is also considered. Well edited and up to date, this volume is recommended reading for allergologists, immunologists, dermatologists and any scientist interested in the immunological events regulating allergic inflammation in general and allergic manifestations in different organs.
