[The role of NADPH-oxidase in paracrine and autocrine regulation of platelet functional activity]
Abstract:
NADPH-oxidase (NOX) is a novel transmembrane enzyme that appears to have pivotal role in the control of platelet signal pathways. The NOX activity in platelets is controlled by agonist receptors activation, which, in turn are modulated by NOX. This review focuses on participation of NOX in autocrine and paracrine regulation of platelet activation, aggregation secretion, protein synthesis and cell recruitment processes during thrombus formation. Possible involving of NOX in the cell-to-cell communication and coordination in response to trombogenic stimulus is discussed.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
Paracrine Signaling
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
