A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. Antagonist drugs interfere in the natural operation of receptor proteins. They are sometimes called blockers; examples include alpha blockers, beta blockers, and calcium channel blockers. In pharmacology, antagonists have WebCell signalling molecules are of the following types: Intracrine ligands: These are produced by the target cell and bind to the receptor within the cell. Autocrine ligands: They function …
