Introduction to Receptor
Definition of receptor, Nature of receptors, Regulations of receptors, Transducer mechanism of receptors and enzyme-link New Rating: 0.0 out of 5 (0 ratings) 0 students 44min of on-demand video Description Definition: It is defined as a macro-molecule or binding site located on cell surface or inside the effector cell that serves to recognize the signal molecule/drug and initiate the response to it, but itself has no other function, e.g. G-protein coupled receptor. Agonist: An agent which activates a receptor to produce an effect similar to a that of the physiological signal molecule, e.g. Muscarine and Nicotine Antagonist: an agent which prevents the action of an agonist on a receptor or the subsequent response, but does not have an effect of its own, e.g. atropine and muscarine. Inverse agonist: an agent which activates receptors to produce an effect in the opposite direction to that of the agonist, e.g. DMCM in BDZ receptors Partial agonist: An agent which activates a receptor to produce submaximal effect but antagonizes the action of a full agonist, e.g. opioids Ligand: any molecule which attaches selectively to particular receptors or sites (only binding or affinity but no functional change). https://www.udemy.com/course/introduction-to-receptor Enjoy! |
