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.

Gliomas, developing in the brain from the transformed glial cells, are a very special kind of tumor, extremely refractory to conventional treatments. Therefore, for the development of new antitumor strategies, a better understanding of molecular mechanisms responsible for their biology, growth and invasion is still needed. This book is a reference on cellular signaling processes regulating gliomas physiology and invasiveness. The work is focused on the mechanism of nucleotide receptor activation by exogenous nucleotides and formation of complex signaling cascades induced by growth factors, cytokines and cannabinoids. The second edition of the book enriched in new chapters provides a framework explaining how signal transduction elements may modulate numerous genetic and epigenetic alterations, describes the role of local microenvironment in cellular growth, progression and invasion and, in the light of extensive new results, presents perspectives concerning potential targets for gliomas therapy.

Adenosine Receptors in Health and Disease available 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.

ATP, the intracellular energy source, is also an extremely important cell–cell signalling molecule for a wide variety of cells across evolutionarily diverse organisms. The extracellular biochemistry of ATP and its derivatives is complex, and the multiple membrane receptors that it activates are linked to many intracellular signalling systems. Purinergic signalling affects a diverse range of cellular phenomena, including ion channel function, cytoskeletal dynamics, gene expression, secretion, cell proliferation, differentiation and cell death. Recently, this class of signalling molecules and receptors has been found to mediate communication between neurons and non-neuronal cells (glia) in the central and peripheral nervous systems. Glia are critical for normal brain function, development and response to injury. Neural impulse activity is detected by glia and purinergic signalling is emerging as a major means of integrating functional activity between neurons, glia and vascular cells in the nervous system. These interactions mediate effects of neural activity on the development of the nervous system and in association with injury, neurodegeneration, myelination and cancer. Bringing together contributions from experts in diverse fields, including glial biologists, neurobiologists and specialists in purinergic receptor structure and pharmacology, this book considers how extracellular ATP acts to integrate communication between different types of glia, and between neurons and glia. Beginning with an overview of glia and purinergic signalling, it contains detailed coverage of purine release, receptors and reagents, purinergic signalling in the neural control of glial development, glial involvement in information processing, and discussion of the interactions between neurons and microglia.

On the one hand, neurophysiology and neuropharmacology are progressing via the single neuron to a subcellular level; on the other, clinicians are studying the function ofthe human urinary system in vivo as a whole. A special effort must be made over the next decade to bridge this gap. We hope that the information summarized here will catalyse the process. In 1968, de Groat and Ryall published a group of papers in the Journal of Physiology in which modern quantitative electrophysiological techniques were applied to the study ofthe reflexes that regulate bladder Junction. These papers represent alandmark in the history of bladder neurophysiology, forming a dividing li ne between old and new. The earlier techniques of lesioning and stimulation of nervous structures yielded mainly qualitative information which was open to criticism because of lack of precise control over what was actually being destroyed or stimulated. Much of this earlier work was reviewed in an authoritative volume by Bors and Comarr in 1971, entitled Neurolqgical Urology. The 16 years have seen great advances in our understanding ofthe control oflower subsequent urinary tract function.
