P2 Purinoceptors

Seemingly simple behaviours turn out, on reflection, to be discouragingly complex. For many years, cognitive operations such as sensation, perception, comparing percepts to stored models (short-term and long-term memory), decision-making and planning of actions were treated by most neuroscientists as separate areas of research. This was not because the neuroscience community believed these operations to act independently—it is intuitive that any common cognitive process seamlessly interweaves these operations—but because too little was known about the individual processes constituting the full behaviour, and experimental paradigms and data collection methods were not sufficiently well developed to put the processes in sequence in any controlled manner. These limitations are now being overcome in the leading cognitive neuroscience laboratories, and this book is a timely summary of the current state of the art. The theme of the book is how the brain uses sensory information to develop and decide upon the appropriate action, and how the brain determines the appropriate action to optimize the collection of new sensory information. It addresses several key questions. How are percepts built up in the cortex and how are judgments of the percept made? In what way does information flow within and between cortical regions, and what is accomplished by successive (and reverberating) stages of processing? How are decisions made about the percept subsequently acted upon, through their conversion to a response according to the learned criterion for action? How does the predicted or expected sensation interact with the actual incoming flow of sensory signals? The chapters and discussions in the book reveal how answering these questions requires an understanding of sensory–motor loops: our perception of the world drives new actions, and the actions undertaken at any moment lead to a new ‘view’ of the world. This book is a fascinating read for all clinical and experimental psychologists and neuroscientists, as well as anyone interested in how we perceive the world and act within it.

Inflammatory bowel disease (IBD) comprises a group of idiopathic diseases of the intestine characterized by chronic inflammation of the bowel with periods of exacerbation and remission. Although the exact cause of IBD remains undetermined, the condition appears to be related to a combination of genetic and environmental factors resulting in an aberrant activation of the mucosal immune system. This book contains a series of interdisciplinary discussions between clinical and basic scientists focusing on key issues such as: Epithelial cell and molecular biology, including apoptosis, necrosis and cell survival The role of bacterial milieu and mucosal bacteria in the IBD and of prebiotic and probiotic therapy The progress towards the identification of susceptibility genes and phenotype-determining genes The pharmacogenetics of IBD Mucosal immunology and therapeutic strategies stemming therefrom

Gramicidin channels have been studied intensively for more than 25 years. They serve as model transport systems for large protein ion channels, since it is difficult to glean high-resolution structural information on the latter. This book includes contributions from virtually all the major scientists studying gramicidin channels and is the only compilation of work in this field. It discusses crystallographic, spectroscopic, electrophysiological and computational studies, especially in the light of the recent availability of high-resolution structural data, and it compares these with insights derived from larger systems. As well as drawing together much new and exciting work in this field, it provides pointers to promising new research directions.

Gramicidin and Related Ion Channel-Forming Peptides

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.

Oxygen sensing is a key physiological function of many tissues, but the identity of the sensor, the signalling pathways linking the sensor to the effector, and the endpoint effector mechanisms are all subjects of controversy. This book evaluates the various mediators that have been proposed, including the mitochondria, NAD(P)H oxidases, cytochrome p450 enzymes, and direct effects on enzymes and ion channels. There has been a resurgence of interest in the role of mitochondria, based partly on the ability of mitochondrial inhibitors to mimic hypoxia, but there is little consensus concerning mechanisms. Some favour the view that the primary signalling event is a reduction in cell redox state and reactive oxygen species (ROS) due to general inhibition of the electron transport chain (ETC); others support a key role for complex III of the ETC and an increase in ROS generation, while others doubt either of these components is the key intermediary. All these hypotheses are discussed in the book, together with conceptual problems concerning the ability of mitochondria to respond to physiological hypoxia. The other area of controversy covered in the book is the identity of the endpoint effector(s). Some authors favour K+ channel inhibition, followed by depolarization and Ca2+ entry via L-type channels, while others propose that release of Ca2+ from intracellular stores, or capacitative Ca2+ entry and other voltage-independent pathways may be more important. The book also describes evidence for an endothelium-dependent Ca2+-sensitizing pathway involving Rho and possibly other kinases. While some of these differences can be attributed to variation between tissues, many must be related to differences in interpretation or methodology. In this book, experts in the field of acute oxygen sensing working in different tissues address these controversies and their possible origins, and discuss possible approaches whereby these controversies might be resolved. The book will be of great interest to all those working in fields where oxygen sensing is important, particularly cancer and wound healing, as well as researchers in drug discovery and biotechnology.

Insect-Plant Interactions and Induced Plant Defence Chair: John A. Pickett, 1999 This book examines the sophisticated mechanisms that plants use to defend themselves against attack by insects and pathogens, focusing on the networks of plant signalling pathways that underlie these defences. In response to herbivory, plants release a complex blend of as many as 100 volatile chemicals, known as semiochemicals ('sign chemicals'). These act as an airborne SOS signal, revealing the presence of the herbivore to the predators and parasitoids that are its natural enemies. Plants also have endogenous defence mechanisms that can be induced in response to pathogens, and separate chapters deal with systemic acquired resistance, phytoalexins, and the interacting pathways in pathogen and pest resistance. The book discusses underlying biochemical mechanisms by which plant stress leads to the biosynthesis of chemical signals from pools of secondary metabolite precursors, or even from the primary metabolism source. Finally, consideration is given to the possibilities for exploiting these signalling pathways by plant molecular genetics. The use of plant signals and their analogues to switch on defence pathways in crop plants is covered in depth. Bringing together contributions from entomologists, chemical ecologists, molecular biologists and plant physiologists this book is truly interdisciplinary, and will be essential reading for anyone with an interest in agricultural pest control.

Insect-Plant Interactions and Induced Plant Defence

The ability at the molecular level to keep track of time is a property shared by organisms ranging from the simplest unicells to humans. The primary feature of these biological clocks is their ability to entrain to environmental stimuli. The dominant stimulus comes from environmental light cues, which requires the existence of photopigments sensitive to light. The exact identity of the molecules involved in circadian photoreception has remained elusive. The classical view of the circadian system is of diverse physiological rhythms regulated by a centralized clock structure. This book presents evidence that challenges this view. Experiments in both vertebrate and invertebrate systems demonstrate that the circadian timing system is dispersed throughout the animal and suggest that possibly every cell contains an autonomous clock mechanism. A variety of tissues and cells contain have been shown to maintain an oscillation when placed in vitro and removed from any external cues or signals that originate from the classical clock structures and/or the environment. This book draws together contributions from an international and interdisciplinary group of experts whose work is focused on all aspects of the topic. Coverage includes the mechanisms of light signalling to the vertebrate clock, the connections between central and peripheral clocks, circadian gene expression patterns and output pathways of clock mechanisms.

Somatostatin and Its Receptors

The use of oligonucleotides as therapeutic agents rests upon their ability to interfere, in a sequence-specific manner, with the fundamental machinery of protein synthesis either by binding to the mRNAs transcribed from a gene or by binding directly to a target gene. This approach can be used not only for inhibition of the synthesis of host proteins but also of those required by invading pathogens. Potential therapeutic applications are enormous, ranging over hypertension, cardiovascular disease, autoimmune disease, vital and other parasitic infections (especially HIV), and cancer. This book discusses the chemistry and pharmacokinetics of oligonucleotides and their analogues, and surveys the results of structure-activity studies and current clinical trials. It also critically reviews the problems with antisense therapy, such as the enzymatic destruction of oligonucleotides, the doses required for a therapeutic response, the difficulty in directing oligonucleotides to particular target tissues and cells, the need for parenteral administration, and doubts concerning the mechanism of action (especially problems associated with non-specific binding to proteins) and long-term effects.

The hERG Cardiac Potassium Channel

Cl- absorption and HCO3- secretion are intimately associated processes vital to epithelial function, itself a key physiological activity. Until recently the transporters responsible remained obscure, but a breakthrough occurred with the discovery of the SLC26 transporters family. It is now clear that the SLC26 transporters have broad physiological functions since mutations in several members are linked to a variety of diseases. This book describes the properties of this family in detail, with contributions from the leading global researchers in the field. Complementary views from experts on other ion channels are offered in the discussions, which make fascinating reading. This family consists of at least 10 genes, each of which has several splice variants. Most members of the family are expressed in the luminal membrane of epithelial cells. Characterization of anion transport by three members has revealed that all function as Cl-/HCO3- exchangers, suggesting that SLC26 transporters are responsible for the luminal Cl-/HCO3- exchange activity. The SLC26 transporters are activated by the CF transmembrane conductance regulator and activate it in turn, leading to a model in which these molecules act together to mediate epithelial Cl- absorption and HCO3- secretion. The book includes chapters on the transport of other molecules by the SLC26 family, including oxalate in the kidney and sugars in cochlear hair cells amongst others. It also describes recent discoveries that most SLC26 transporters bind to scaffold proteins and that they all contain a conserved domain predicted to participate in protein-protein interactions. These suggest the SLC26 transporters exist in complexes with other Cl- and HCO3- transporters, and possibly other regulatory proteins. This book explores the functional role of these interactions, leading to better understanding of transepithelial fluid and electrolyte secretion and the diseases associated with it.

Functional Anatomy of the Neuroendocrine Hypothalamus

The heat shock, or cell stress, response was first identified in the polytene chromosomes of Drosophila. This was later related to the appearance of novel proteins within stressed cells, and the key signal stimulating this appearance was identified as the presence of unfolded proteins within the cell. It is now known that this is a key mechanism enabling cells to survive a multitude of physical, chemical and biological stresses. Since the promulgation of the ‘molecular chaperone’ concept as a general cellular function to control the process of correct protein folding, a large number of molecular chaperones and protein folding catalysts have been identified, and it has been recognized that not all molecular chaperones are stress proteins and vice versa. The discovery of molecular chaperones as folding proteins went hand-in-hand with their recognition as potent immunogens in microbial infection. It was subsequently shown that administration of molecular chaperones such as Hsp60, Hsp70 or Hsp90 could inhibit experimental autoimmune diseases and cancer. More recently evidence has accumulated to show that certain molecular chaperones are also present on the surface of cells or in extracellular fluids. A new paradigm is emerging: at least some molecular chaperones are secreted proteins with pro- or anti-inflammatory actions, regulating the immune response in human diseases such as coronary heart disease, diabetes and rheumatoid arthritis. In addition to having direct effects on cells, molecular chaperones can bind peptides and present them to T cells to modulate immune responses. This may be significant in the treatment of cancer. This is the first book bringing leading researchers in this field together to review and discuss: our current knowledge of cell stress response and molecular chaperones the changing paradigms of protein trafficking and function cell stress proteins as immunomodulators and pro- and anti-inflammatory signalling molecules the role of these proteins in various chronic diseases and their potential as preventative or therapeutic agents. The Biology of Extracellular Molecular Chaperones is of particular interest to immunologists, cell and molecular biologists, microbiologists and virologists, as well as clinical researchers working in cardiology, diabetes, rheumatoid arthritis and other inflammatory diseases.

Bioactive Compounds from Plants

Antibiotic Resistance: Origins, Evolution, Selection and Spread Chairman: Stuart B. Levy, 1997 Over the last 50 years, the rapid increase in the use of antibiotics, not only in people, but also in animal husbandry and agriculture, has delivered a selection unprecedented in the history of evolution. Consequently, society is facing one of its gravest public health problems-the emergence of infectious bacteria with resistance to many, and in some cases all, available antibiotics. This book brings together a multidisciplinary group of experts to discuss this problem. It begins by examining the origins of resistance and goes on to look at how the use of antibiotics in human medicine and farming/agriculture has selected for resistant bacteria. Separate chapters describe the evolution of resistance determinants and how these are spread both within and between bacterial species. Finally, the book contains discussions on strategies for countering the threat of antibiotic resistance. A major re-thinking of our approach to the treatment of infectious diseases is proposed-that antibiotic resistance should be seen as a problem created by the disruption of normal microbial ecology. To restore efficacy to earlier antibiotics, and to maintain the success of new antibiotics that are introduced, we need to use these drugs in a way that ensures an ecological balance that favours the predominance of susceptible bacteria.
