ADRENERGIC PHARMACOLOGY University of Kentucky. Receptor pharmacology is the study of the interactions of receptors with endogenous ligands, drugs/pharmaceuticals and other xenobiotics. In order to understand the molecular mechanism underlying a ligand's effect on physiological or therapeutic cellular responses a number of basic principles of receptor theory must be considered., Department of Pharmacology, Weill Medical College of Cornell University, and the Pain and Palliative Care Service, Memorial Sloan-Kettering Cancer Center, New York, New York, U.S.A. Abstract: The pharmacological effects of the opioid analgesics are derived from their complex interactions with three opioid receptor types (m, d, and k; morphine is an agonist at the m opioid receptor). These.

We combined a study of the subcellular distribution of the О±1, О±2, О±4, ОІ1, ОІ2/3, Оі2, and Оґ subunits of the GABA A receptor with an electrophysiological analysis of GABA A receptor currents determine the to types of receptors expressed on cultured hippocampal pyramidal neurons. Receptors are macromolecules involved in chemical signaling between and within cells; they may be located on the cell surface membrane or within the cytoplasm (see Table: Some Types of Physiologic and Drug-Receptor Proteins). Activated receptors directly or indirectly regulate cellular biochemical processes (eg, ion conductance, protein phosphorylation, DNA transcription, enzymatic activity).

Histamine plays a major pleiotropic role in mammals through binding to four types of G-protein-coupled receptors, designated as H1-H4. For more than 75 years, histamine has been one of the most exploited substances in medicine, providing blockbuster H1 and H2 antihistamines for the treatment of allergies and gastric disorders, respectively. This chapter describes the structure, pharmacology, and function of γ‐aminobutyric acid type A (GABA A) receptor subtypes. GABA A receptors are the most important inhibitory transmitter receptors in the central nervous system (CNS).
