The Delta Receptor spans current research in delta receptor biology, pharmacology, physiology, and chemistry to identify, advance, and inspire the development of novel drug candidates. It demonstrates the potential significance and impact of the delta receptor in the therapy and treatment of medical conditions such as pain, gastrointestinal disorders, bladder dysfunction, and depression, as well as heart attack prevention. This reference examines the pathophysiological functions and mechanisms of receptor-selective drugs. Documenting key advances in the field, The Delta Receptor represents the most comprehensive and up-to-date studies on receptor applications currently available. 1.

Includes Bibliographical References And Index. The discovery of two endogenous opiate- or morphinelike peptides, Leu-enkephalin and Met-enkephalin, by Hughes and colleagues in 1975 [1] led to the explosive advances in our understanding of the functions of opioid receptors and the actions of opiates and opioids in the last two decades.
