The purpose of the present volume, the first of two on the pharmacology, biochemistry, and physiology of cyclic nucleotides, is to provide a comprehensive and up-to-date anthology on the nature and role of these important chemical regulators. Each of the chapters is the work of internationally known researchers who present a lucid and detailed review of their subject and not merely a single laboratory's viewpoint. The chapters emphasize critical assessments of the field rather than mere listings of experimental findings. By so doing, the contributors present the role of cyclic nucleotides in relationship to other intracellular regulators. Each chapter begins with a detailed summary to allow the reader to obtain a rapid overview of subsequent material. In addition, there are extensive bibliographies and a detailed subject index. Wherever pertinent, the chapters contain sections on drug mechanisms, physiological relevance, and disease processes. The Volume is divided into two sections, each beginning with an overview written by Professors T. W. RALL and P. GREENGARD, respectively. The first section focuses on the detailed pharmacology and chemistry of cyclic nucleotides, including their formation, degradation, measurement, and interaction with various modulatory agents, such as receptors and calcium. The second section is concerned with the biochemistry of protein phosphorylation, a process which appears to be one of the most important mechanisms for the intracellular expression of cyclic nucleotide action in eukaryotic cells.

The detection of neurotransmitter receptor locations and distribution densities within the central nervous system and peripheral tissues is receiving intense attention within the neuroscience research community. Neurotransmitter receptors, which receive the chemical signals sent from one neuron to another, are critical links in a highly complex information-processing chain. Pinpointing receptor sites and systems is crucial for understanding neurological function as well as dysfunction. It is also essential for understanding how receptors process information when impacted by such substances as heroin or nicotine, or when affected by neurodegenerative disease.
Receptor Localization: Laboratory Methods and Procedures is the first user-friendly guide to the latest techniques and approaches being employed to examine the localization of neurotransmitter receptors in the central nervous system and peripheral tissues. It covers detection methods that are applicable to a wide variety of receptor systems, ranging from genes and ligands to in vito receptors in individuals; and to numerous receptor subtypes, such as nicotine, muscarine, tackykinins, dopamine, adenosine, and GABA. The standard laboratory "recipes" or "tricks" employed in these detection methods are fully discussed, as are the advantages and limitations of each procedure. With contributions from leading experts and extensively illustrated, this book:
* Discusses receptor ligand binding methods using irreversible and reversible compounds
* Presents antireceptor antisera technology using synthetic peptides and fusion proteins at both the cellular and subcellular resolution levels
* Examines molecular assessments of receptors
* Describes in situ hybridization, reverse transcriptase-PCR, and fluorescent in situ transcription
* Covers new visualization paradigms
* Includes physiological analysis of receptor function, cellular detection in the brain slice, and cultured neurons
* Discusses the use of PET and SPECT to assess in vivo receptor distributions in animals and humans

Receptor Localization: Laboratory Methods and Procedures is an invaluable guide for researchers in the related fields of neurology, biochemistry, and pharmacology. Its lucid descriptions of new detection methods, inclusion of experimental examples, and emphasis on how these experimental approaches are applicable to particular research areas will appeal to both the experienced researcher and novice investigator.
