beta-adrenoceptor Sentence Examples
- Beta-adrenoceptors are receptors that bind adrenaline and noradrenaline, hormones that mediate the sympathetic nervous system's "fight or flight" response.
- Beta-adrenoceptors have two main subtypes, beta-1 and beta-2, which differ in their location, function, and affinity for different agonists and antagonists.
- Beta-1 adrenoceptors are primarily found in the heart, where they mediate the effects of catecholamines on heart rate and contractility.
- Beta-2 adrenoceptors are more widely distributed, found in smooth muscle, vascular tissue, and the lungs, where they regulate bronchodilation and vasodilation.
- Beta-blockers, such as propranolol and metoprolol, are drugs that competitively bind to beta-adrenoceptors and block their activation, which is used to treat conditions like hypertension and arrhythmias.
- Beta-agonists, such as salmeterol and albuterol, are drugs that activate beta-adrenoceptors, which is used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD).
- The stimulation of beta-adrenoceptors by catecholamines increases heart rate, blood pressure, and cardiac output, preparing the body for physical activity or stress.
- Beta-adrenoceptors are also involved in regulating airway resistance, glycogenolysis, lipolysis, and other metabolic processes.
- Dysregulation of beta-adrenoceptors can contribute to various cardiovascular and respiratory disorders, including hypertension, heart failure, and asthma.
- Research into beta-adrenoceptors has led to the development of novel therapeutic strategies for treating a wide range of conditions.
