DOWNLOAD EBOOKThese volumes record the presentations made at the VIII International Symposium on Purine and Pyrimidine Metabolism in Manheld at Indiana University, Bloomington, USA from May 22- May 27, 1994. This was a continuation of meetings held every three years with the idea of bringing clinicians and basic scientists together, which we hope results in cross-fertilization of ideas. Some of the papers presented in this volume represent oral contributions and others are from posters, but we emphasize that both are considered of equal merit. As is obvious from a perusal of the titles of the papers there has been a shift in the focus of this meeting, which reflects a general shift in the area of purine and pyrimidine metabolism. The emphasis has definitely shifted to gene structure and molecular genetics, with the beginnings we hope of gene therapy as an important branch of this area of science. Although many of the inherited diseases discussed in this text can be treated with drugs, the major thrust in the futurewill be in gene therapy, where the gene (or cDNA) will be used to treat the patient with enzyme deficiency, particularly if the patient is young. As can be seen from the Iist of authors there is a remarkable degree of international cooperation in this area across countries and continents. We thank the many participants who have attended these symposia many times, and we welcome the large group of scientists from Eastern Europe who are attending this meeting for the first time.

DOWNLOAD EBOOKIn 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 EBOOKth th This volume comprizes articles presented at the joint IX International and 6 Euro pean Symposium on Purine and Pyrimidine Metabolism in Man held in Gmunden, Austria, June 1 through 7, 1997. Since the first of this series of meetings was held in Israel in 1973, conventions were organized every three years in different parts of the world including the USA, Japan, and Europe. The different aspects of purine and pyrimidine metabolism bring together re searchers working in molecular genetics, biochemical pharmacology, biochemistry, devel opmental biology, immunology, epidemiology and the clinics. Oriented research in the field has been seminal for the development of potent anticancer and antiviral drugs. As the number of genes which are cloned, grows, the understanding of metabolism is increas ingly enlarged and might provide leads to further improve therapeutic concepts and to bet ter understand mechanisms responsible for the development of resistance against these drugs. In certain diseases purine and pyrimidine analogs represent not only the drugs of choice but in fact are the sole therapeutic alternative at present. The field has also taken an early lead in attempting to correct inborn errors of purine and pyrimidine metabolism by gene therapy. The organization of this meeting involved a large number of people who dedicated their time in an effort to make this symposium a success. We thank the Abstract Review Committee, the International Advisory Board and in particular the Symposium Secretariat for doing a wonderful job.

DOWNLOAD EBOOKPhysiological, pharmacological and molecular biological data generated over the past three decades have demonstrated the existence of two major families of extracellular receptors, the P1, a family of four G-protein coupled receptors and the P2, a family of at least 12 receptors responsive to purine (ATP, ADP) and pyrimidine (UTP) nucleotides through which adenosine and ATP can function as extracellular messengers. The present two-part volume represents an integrated compendium of invited chapters by leading researchers in the area focusing on advances in the understanding of purinergic and pyrimidinergic signaling systems, their role(s) in tissue function and pathophysiology and advances in developing potential new medications based on the modulation of P1 and P2 receptor signaling processes. The volumes will thus provide the reader with a topical, comprehensive and integrated overview of this important area.

DOWNLOAD EBOOKPurine receptors are a type of plasma membrane molecules found in nearly all mammalian tissues. They are classified into three categories and include P1 receptors, P2X receptors, and P2Y receptors. They all play a key role in the variety of neuronal and non-neuronal mechanisms, which comprise pain, immune responses, exocrine and endocrine secretion, platelet aggregation, endothelial-mediated vasodilatation, and inflammation. The G protein is mainly bound to the P1 and P2Y receptors. These receptors are differentiated by considering their reactivity towards particular activators. The brain, heart, kidneys, and adipose tissue all contain P1 and P2Y receptors. These receptors are responsible for various cellular functions, comprising vascular reactivity, migration and proliferation of neural stem cells, cytokine secretion and apoptosis. The study of purine receptors is helpful for developing therapeutic strategies for those disorders, which have new action mechanisms, such as pathogenic conditions, like trauma, pain, epilepsy, ischemia, drug dependence and psychiatric disorders. The objective of this book is to present advanced studies on purine receptors as well as their pharmacological applications. Those in search of information to further their knowledge will be greatly assisted by it.

DOWNLOAD EBOOKThese two volumes record the scientific and clinical work presented at the VIIth International and 3rd European joint symposium on purine and pyrimidine metabolism in man held at the Bournemouth International Conference Centre, Bournemouth, UK, from 30th June to 5th July 1991. The series of international meetings at three yearly intervals have previously been held initially in 1973 in Israel, then Austria, Spain, the Netherlands, USA and Japan. The European society for the Study of Purine and Pyrimidine Metabolism in Man (ESSPPM) which has its own executive and some finance first met in Switzerland in 1987, then in Germany in 1989. The steady evolution of the science in this series of meetings is intellectually satisfying; the subsequent clinical progress is emotionally and economically reassuring. As befits the position of purines and pyrimidines at the centre of biochemistry, there has been steady scientific development into molecular genetics and now onto developmental controls and biochemical pharmacology. The complexities of the immune system are being unravelled but an understanding of the human brain largely eludes us. Laboratory based scientists now predominate over those who work as clinical specialists in vii rheumatology, immunology, oncology and paediatrics. However, there continue to be major clinical objectives since large sections are concerned with major causes of death like ATP depletion, cancer and now AIDS; the laboratory work is providing clinical solutions.
