Abstract

In this review, we discuss the role of adrenoceptors in the regulation of the rheological functions of erythrocytes. β-adrenoceptors play an important role in the regulation of erythrocytes functions and metabolism. They participate in the modification of transport membrane proteins (Na+/K+-ATPase, Ca+2-ATPase, Na+/K+/2Cl-cotransporter, Na+/H+-antiporter, CAT-1, Ca2+-dependent K+ channels (Gard channels), the activity of adenylate cyclase and cAMP, AMP-dependent activation of the L-arginine/NOS system and erythrocyte NOS) and by this way modulate the cells volume, rheological properties (deformability, aggregability), intensity of NO synthesis and ATP reliase. These properties of erythrocytes determine, that, in addition to the transport of gases, they play the oxygen sensors role and can participate in the mechanisms of vasorelaxation and maintenance of a normal level of microcirculation.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
