α2-Adrenergic receptors (α2ARs) are essential components of the neural circuitry regulating
cardiovascular function. The role of specific α2AR subtypes (α2a, α2b, and α2c) was …

In this review, subtypes of functional α1-and α2-adrenoceptors are discussed. These are cell
membrane receptors, belonging to the seven transmembrane spanning G-protein-linked …

We have attempted to define the alpha adrenoceptor subtype (s) on which intrathecally
applied alpha adrenergic agonists act to produce their antinociceptive effect. The potencies …

The purpose of this study was to determine whether both alpha 1-and alpha 2-adrenergic
receptors exist on vascular smooth muscle of microvessels and whether adrenergic …

The concept of pre-and postjunctionally located a adrenoceptors, as well as the more recent
subdivision into ax and a2 subtypes, has initiated duringthe last decade a renaissance of …

In this review the classification of a-adrenoceptors into two major subgroups is discussed, an
idea which derived primarily from studies on the pre-and postsynaptic a-receptors at …

The concept of two types of alpha-adrenoceptor, alpha 1 located on smooth muscle and
mediating contraction and alpha 2 located on nerve terminals and mediating inhibition of …

Abstract α-Adrenoceptors may be subdivided based on their anatomical distribution within
the synapse. Presynaptic α-adrenoceptors are generally of the α 2-subtype and modulate …

The pre-and post-junctional effects of five α-adrenoceptor agonist drugs were examined in
the pithed rat. On pre-junctional receptors on the cardioac-celerator nerves, oxymetazoline …

It is well known that the vascular endothelial cell layer plays an essential role in the
vasodilatory response of several agents. In this study we have investigated the possibility …
