WebCell signaling pathways are involved in the pathophysiology of many diseases. Cancer is a disease of signaling malfunction due to inactivation of a growth-inhibiting (tumor suppressor) pathway, or to activation of a growth-promoting (oncogene) pathway by … 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
