Vasopressors can act on the alpha-1, beta-1, and beta-2 adrenergic receptors. They also can act on dopamine receptors. These drugs stimulate smooth muscle contraction in the blood vessels.

Thyroid hormones exert their effects through alpha (TRα1) and beta (TRβ1 and TRβ2) receptors. Here we describe a child with classic features of hypothyroidism (growth retardation, developmental ...

Fan and his colleagues deleted three different forms of the receptors (alpha, beta, and gamma) in the muscle tissues of mice and examined the resulting effects. They found that while the most ...

Beta-adrenergic blockers function as ... organ responses to catecholamine drugs that he labeled alpha- and beta-adrenergic receptor mediated. Fifty-year history In 1958 the compound ...

G-protein coupled receptors regulate hormone secretions ... Within islets, beta cells secrete insulin, and alpha cells secrete glucagon. Scientists have identified three additional cell types ...

Chemically, epinephrine and norepinephrine are very similar. Both epinephrine and norepinephrine work on alpha and beta receptors. However, epinephrine has a greater effect on beta receptors ...

Carvedilol is a non-selective beta-blocker that works by blocking beta-1 receptors located in the heart and beta-2 receptors in the blood vessels and lungs. This blocks the actions of chemicals ...
