The goal of this text is to focus readers attention on three major areas; the origin and localization of GSH in the nervous system; the multiple effects of GSH on neural health activity; and the potential for alterations on GSH status to lead to neurological damage of the type observed in amyotrophic lateral sclerosis, Parkinson's disease and other neurological disorders. The text also touches upon the additional roles of the antoxidant GSH, including possible neurotransmitter action, redox modulation of ionotropic receptor function, and neuroprotection against exicitoxic actions of glutamate.

Latest research on Adhesion GPCRs has unearthed surprising revelations about the events that govern the signal transduction of these receptor molecules and the cellular and organ requirements for these signals. Unexpected and unprecedented findings suggest that Adhesion GPCRs constitute a group of receptors that sense mechanical stimuli and transcode them into metabotropic signals through the action of a novel activation paradigm. Interdisciplinary efforts transcending many areas of biomedical research including pharmacology, physiology, genetics, cell biology, structural biology, biochemistry and bioinformatics were necessary to unveil these fundamental properties. The scientific leaders in the field that carried this research effort have teamed up here to provide a comprehensive overview of our current understanding, how Adhesion GPCRs signal and how these receptors shape organ structure and function.

A number of techniques to study ion channels have been developed since the electrical basis of excitability was first discovered. Ion channel biophysicists have at their disposal a rich and ever-growing array of instruments and reagents to explore the biophysical and structural basis of sodium channel behavior. Armed with these tools, researchers have made increasingly dramatic discoveries about sodium channels, culminating most recently in crystal structures of voltage-gated sodium channels from bacteria. These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs and toxins with which they are known to interact, acquired and inherited diseases that affect sodium channels and the techniques with which their biophysical and structural properties are studied.

In the last two decades, our knowledge on regulatory peptides and their cognate receptors, most of which are members of the seven transmembrane receptor families, has increased enormously. Regulatory peptides are small proteins which, besides their hormonal functions in regulating cellular metabolism in various tissues, may also act as neurotransmitters, and thus they often carry the prefix'neuro'. Many of the cognate receptors involved in transducing the peptidergic signal across the cell membrane via a familiy of G proteins exist in multiple forms, the number of which frequently exceeds that of the corresponding peptide ligands. In this book, various peptide-receptor systems are discussed, e.g CRF, somatostatin, TRH, opioid peptides, vasopressin, and oxytocin. It also discusses new strategies such as'reverse physiology'to uncover new peptides and orphan receptors.

Among the many GPCRs discovered, the calcitonin family of receptors comprise of members that regulate a number of physiological processes and are involved in many pathological conditions. Therefore, understanding how these receptors function is a critical question in the field. When Foord and his colleagues discovered that a single transmembrane protein called Receptor Activity Modifying Proteins (RAMPs) could modulate the surface expression of GPCRs of the calcitonin family, it widely opened the field of receptor life cycle. Hundreds of studies have confirmed the importance of RAMPs in the life cycle of this receptor family. Receptor biology is a rapidly expanding field and with the advances in cell and molecular biology and in vivo techniques, it is very likely that the field of RAMPs will explode further and many unanswered questions will be answered with in the next few years.

One of the major goals of researchers in the field of apoptosis is to identify targets for novel therapies in cancer, AIDS, and Alzheimer's disease. Understanding the molecular mechanisms of the various components of the apoptotic pathways is the first step to reaching this goal. The 2002 Nobel Prize in Physiology or Medicine was awarded to Sydney Brenner (United Kingdom), H. Robert Horvitz (US) and John E. Sulston (UK)'for their discoveries concerning genetic regulation of organ development and programmed cell death.'Cell death is a fundamental aspect of embryonic development, normal cellular turnover and maintenance of homeostasis (maintaining a stable, constant environment) on the one hand, and aging and disease on the other. This volume addresses the significant advances with the techniques that are being used to analyze cell death. - This volume provides the necessary, trusted methods to carry out this research on these latest therapeutic techniques. Once researchers understand the molecular mechanisms of the apoptotic pathways, they can begin to develop new therapies - Presents key methods on studying tumors and how these cancer cells evade cell death - Eliminates searching through many different sources to avoid pitfalls so the same mistakes are not made over and over
