Originally confused with opioid receptors and then orphan receptors with no biological function, Sigma Receptors are now recognized as relevant to many degenerative diseases with remarkable potential as therapeutic targets. In this text, new information about the structure of sigma 1 receptor, its binding sites are provided as well as its expression in many cell types. It’s putative role in degenerative neuronal diseases including amyotrophic lateral sclerosis, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, pain, drug addiction and locomotor activity. Their roles in possible treatments for blinding retinal diseases emphasize the tremendous far-reaching potential for ligands for these receptors. Exciting breakthroughs in this dynamic field in the last decade are reported herein, which will guide future investigators in determining the full potential of this unique, yet abundantly expressed protein.
In Glutamate and Addiction, world-renowned scientific experts critically review all of the evidence for the role of glutamatergic systems in opiate, stimulant, and alcohol addiction. Using a variety of pharmacological, biochemical, genetic, and brain imaging techniques, these investigators show precisely how glutamate affects such addictions and how modifying certain elements of the glutamatergic system appear to alleviate particular components of addiction. Their survey takes in both clinical approaches using medications that influence glutamate and cutting-edge preclinical approaches that manipulate specific subtypes of glutamate receptors or specific substrates of the "glutamate cascade" to determine their roles in various addictive states.
Includes bibliographical references and index.
The sigma receptor was originally thought to be a subset of the opioid receptor family, and it is less than 10 years since it was recognized that this receptor represents unique binding sites in mammalian brain and peripheral organs, distinct from any other known neurotransmitter receptor.

This book provides an update on sigma receptors, and summarizes recent advances in the medicinal chemistry, molecular biology, and cell biology of sigma receptors. It describes the functional effects mediated by these receptors and the potential clinical implications of these actions. The information is put in a historical perspective. This provides a launching point from which future studies and research directions can easily be developed.
