Research on purine derivatives as potent and selective modulators of physiologic functions has moved to center stage. This volume covers the biology and chemistry of purines and of their receptors broadly under these section headings: - Adenosine Receptors and Effector Systems - Adenine Nucleotide Receptors and Effector Systems - Phosphodiesterase Enzymes and Inhibitors The presentations focus on the potential development of clinically useful drugs and powerful agents that activate or block purinergic receptors or that inhibit phosphodiesterases. Xanthines (caffeine and theophylline) represent one class of such agents. This volume is for pharmacologists, biochemists, and medical chemists in research labs of universities, gov- ernment, and the pharmaceutical industry.

Download Purines as transmitter molecules. Electrophysiological studies on purinergic signalling in different cell systems Book in PDF, ePub and Kindle
Purinergic nucleotides and nucleosides (ATP, ADP, AMP and adenosine) are essential intracellular metabolites involved in a number of cellular processes, from energy supply to protein phosphorylation. However, in the last years, several studies demonstrated their involvement in cell signalling by the activation of specific membrane receptors (P1 and P2) and their role as neurotransmitters began to be investigated. The present work was aimed to clarify the effects of purinergic neurotransmission in different cell systems by using electrophysiological techniques. Relevant results of this research include the observation that P1 and P2 receptors play a deleterious role during "in vitro" ischemia in the rat brain, and the first demonstration of P2 receptor expression and function in a line of adult human mesenchymal stem cells.

Download Purinergic Signalling and the Nervous System Book in PDF, ePub and Kindle
In the first 20 years that followed the purinergic signalling hypothesis in 1972, most scientists were sceptical about its validity, largely because ATP was so well established as an intracellular molecule involved in cell biochemistry and it seemed unlikely that such a ubiquitous molecule would act as an extracellular signalling molecule. However, after the receptors for ATP and adenosine were cloned and characterized in the early 1990s and ATP was established as a synaptic transmitter in the brain and sympathetic ganglia, the tide turned. More recently it has become clear that ATP is involved in long-term (trophic) signalling in cell proliferation, differentiation and death, in development and regeneration, as well as in short-term signalling in neurotransmission and secretion. Also, important papers have been published showing the molecular structure of P2X receptors in primitive animals like Amoeba and Schistosoma, as well as green algae. This has led to the recognition of the widespread nature of the purinergic signalling system in most cell types and to a rapid expansion of the field, including studies of the pathophysiology as well as physiology and exploration of the therapeutic potential of purinergic agents. In two books, Geoffrey Burnstock and Alexej Verkhratsky have aimed at drawing together the massive and diverse body of literature on purinergic signalling. The topic of this first book is purinergic signalling in the peripheral and central nervous systems and in the individual senses. In a second book the authors focus on purinergic signalling in non-excitable cells, including those of the airways, kidney, pancreas, endocrine glands and blood vessels. Diseases related to these systems are also considered.

Download Adenosine Receptors in Health and Disease Book in PDF, ePub and Kindle
Since their discovery approximately 25 years ago, adenosine receptors have now emerged as important novel molecular targets in disease and drug discovery. These proteins play important roles in the entire spectrum of disease from inflammation to immune suppression. Because of their expression on a number of different cell types and in a number of different organ systems they play important roles in specific diseases, including asthma, rheumatoid arthritis, Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, heart disease, stroke, cancer, sepsis, and obesity. As a result of intense investigations into understanding the molecular structures and pharmacology of these proteins, new molecules have been synthesized that have high specificity for these proteins and are now entering clinical trials. These molecules will define the next new classes of drugs for a number of diseases with unmet medical needs.

Download Biomarkers in Inborn Errors of Metabolism Book in PDF, ePub and Kindle
Biomarkers of Inborn Errors in Metabolism: Clinical Aspects and Laboratory Determination is structured around the new reality that laboratory testing and biomarkers are an integral part in the diagnosis and treatment of inherited metabolic diseases. The book covers currently used biomarkers as well as markers that are in development. Because biomarkers used in the initial diagnosis of disease may be different than the follow-up markers, the book also covers biomarkers used in both the prognosis and treatment of inherited metabolic disorders. With the introduction of expanded new-born screening for inborn metabolic diseases, an increasing numbers of laboratories are involved in follow-up confirmatory testing. The book provides guidance on laboratory test selection and interpreting results in patients with suspected inherited metabolic diseases. The book provides comprehensive guidance on patient diagnosis and follow-up through its illustrative material on metabolic pathways, genetics and pathogenesis, treatment and prognosis of inherited metabolic diseases, along with essential information on clinical presentation. Each chapter is organized with a uniform, easy-to-follow format: a brief description of the disorder and pathway; a description of treatment; biomarkers for diagnosis; biomarkers followed for treatment efficacy; biomarkers followed for disease progression; confounding conditions that can either: affect biomarker expression or mimic IEMs; other biomarkers: less established, future. Provides comprehensive information on the tests/biomarkers selection in newborn screening and follow-up of newborn screens Categorizes biomarkers into diagnostic markers, disease follow-up markers, and prognostic biomarkers Covers confounding factors that can alter biomarkers in the absence of inborn errors of metabolism Offers guidance on how to distinguish acquired causes from inborn errors of metabolism

Download Stem Cells Book in PDF, ePub and Kindle
Since different types of stem cells for therapeutic applications have recently been proposed, this timely volume explores various sources of stem cells for tissue and organ regeneration and discusses their advantages and limitations. Also discussed are pros and cons for using embryonic stem cells, induced pluripotent stem cells, and adult stem cells isolated from postnatal tissues. Different types of adult stem cells for therapeutic applications are also reviewed, including hematopoietic stem cells, epidermal stem cells, endothelial progenitors, neural stem cells, mesenchymal stem cells, and very small embryonic-like stem cells. This book also addresses paracrine effects of stem cells in regenerative medicine that are mediated by extracellular microvesicles and soluble secretome. Finally, potential applications of stem cells in cardiology, gastroenterology, neurology, immunotherapy, and aging are presented. This is an ideal book for students and researchers working in the stem cell research field.
