To test the hypothesis that nonselective blockade of adrenergic receptor (AR) subtypes is superior to selective blockade of AR subtypes in suppressing left ventricular (LV) remodeling induced by ...

Upon binding to the α 2a-adrenergic receptor, these compounds preferentially activated intracellular signaling pathways that were limited to a few subtypes of G proteins.

Using inhibitors of different subtypes of adrenergic receptors—α1-, α2-, and β-ARs—the scientists found that NE shushing synapses required only α1-ARs. This surprised them at first, because engagement ...

This article reviews the current state of knowledge and understanding of the genetic variation present in the three human beta-adrenergic receptor genes.

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.
