Receptor Autoradiography by Dr. John Wharton,Julia M. Polak Pdf
Receptor autoradiography is an invaluable technique that is widely used to localize and characterize peptide and neurotransmitter binding sites. Its extensive use reflects the utility of the technique and the important advantages it offers over conventional biochemical procedures. This instructive work makes receptor autoradiography more accessible by giving a detailed account of the methodology and its application in the analysis of receptors in the brain and peripheral organs. These examples are not exhaustive but illustrate the versatility of the technique as well as its potential pitfalls. The book provides an introduction to the receptor concept and gives detailed information on the theory and procedures involved in the autoradiographic localization and quantification of radiolabelled ligand binding sites. This volume will be an essential tool for neuroscientists, pharmacologists, histochemists, neuropathologists, researchers in the pharmaceutical industry, and students of the biological sciences.
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.

Receptors in the Human Nervous System by F. A. O. Mendelsohn,George Paxinos Pdf
Receptors in the Human Nervous System is a synthesis of the results of receptor mapping by leaders in the field. In addition to a comprehensive discussion of the distribution and possible interactions of the receptors of different neuroactive substances, this book also contains an abundance of pictorial representations of receptor distributions. High-quality photographs of one receptor are often juxtaposed with photographs of the distribution of a different receptor or receptor subtype for the consideration of possible interactions between different systems. The book surveys the distribution of receptor subtypes for the classical monoamine transmitters (acetylcholine, adrenaline, noradrenaline and serotonin) as well as the distribution of receptors for the excitatory and inhibitory amino acids, (glutamate, GABA and benzodiazepines) as well as the opioid peptides, angiotensen and other neuropeptides. The distribution of multiple types of serotonin receptors is given in detail, and the codistribution of receptors in the cortex is discussed. The book is directed toward researchers in the field of chemical neuroanatomy, as well as pharmacologists, neurophysiologists, and neuroscientists.

Peptide Receptors by Remi Quirion,Anders Björklund,Tomas Hökfelt Pdf
Peptide Receptors Part I was published in 2000 (as volume 16 of the Handbook of Chemical Neuroanatomy series). This volume summarized current knowledge on the discrete anatomical distribution of ten families of neuropeptide receptors expressed in the mammalian CNS. Part II is its natural complement with chapters covering six additional families of neuropeptide receptors for ligands ranging from well known peptides such as the opioids and neurotensin to recently isolated ones like the orexins. As in the case of Part I, this volume integrates photomontages and maps of quantitative receptor autoradiography, in situ hybridization histochemistry and immunocytochemistry. Data derived from transgenic and knock-out animals are also summarized, helping to decipher the possible physiological and Pathophysiological role(s) of a given peptide family. Some chapters also review current knowledge on the profile of internalization of the neuropeptide-receptor complex, an area of intense research activities that should help to better understand mechanisms involved in desensitization and tachyphylaxis.
J. M. Polak and S. R. Bloom For some time Experientia has published, as a unique feature, interdis ciplinary multi-author reviews, giving a comprehensive overview of sub jects regarded as 'growing edges' of science. The enthusiasm shown by the readers was contagious and thus it was felt necessary to compile a special volume dealing with the novel aspects of regulatory peptides. This book covers some of the growing areas in regulatory peptide research and, although it is based on the original volume of Experientia, it is expanded and updated. The topic of 'regulatory peptides' is relatively young and has grown at an unprecedented pace, from the embryonic conception of 'gut hor mones' or 'brain neuropeptides' some 15 years ago to the realisation that these active pep tides are found, almost without exception, in every part of l8 23 the body in all vertebrate and many invertebrate species • Why the term 'regulatory peptides'? It represents a convenient label encompassing both the active peptides present in nerves, which are re leased as (putative) neurotransmitters, and those in endocrine cells, which act locally or at a distance as circulating hormones, these being the l8 main components of the so-called diffuse neuroendocrine or APUD 17 system • Morphological studies support this physiological viewpoint.
Because of the significance of morphology and cellular communication unique to the functioning and interdependence of neural systems, many of the advances in the neurosciences rely on classic as well as new microscopy techniques. A convenient bench-top format**Methods presented for easy adaptation to new systems**Comprehensive protocols included for**Autoradiography: measurement of hormone receptors, high-resolution techniques, double labeling and combined techniques**Statistical and computational methods: video imaging, three-dimensional reconstructions, means of structural quantitation, unbiased sampling methods, measurement of analysis of neuronal connections, staining, and individual axon arbors**Tracing neuronal connections: tracer, toxin, and dye methods**Staining techniques: fluoro-gold, SITS, and silver impregnation**Freezing techniques: freeze fracture and cryoprotection**Combined and high-resolution techniques: double-label tracer techniques, incident light polarization, light and electron microscopic techniques
This book describes levels of autoradiography, which is the localization within a solid specimen of a radiolabel, to help the beginner or biologist choose the correct approach for particular application. It attempts to lay emphasis on certain aspects of the appraisal of autoradiographs.
