©2020 Ferrata Storti Foundation Prostacyclin (PGI2) controls platelet activation and thrombosis through a cyclic adenosine monophosphate (cAMP) signaling cascade. However, in patients with cardiovascular diseases this protective mechanism fails for r...

Background Platelet adhesion to von Willebrand factor (VWF) is modulated by 3′,5′-cyclic adenosine monophosphate (cAMP) signaling through protein kinase A (PKA)-mediated phosphorylation of glycoprotein (GP)Ibβ. A-kinase anchoring proteins (AKAPs) are...

Oxidized LDL activates blood platelets through CD36/NOX2–mediated inhibition of the cGMP/protein kinase G signaling cascade (2015)
Journal Article
Magwenzi, S., Woodward, C., Wraith, K. S., Aburima, A., Raslan, Z., Jones, H., …Naseem, K. M. (2015). Oxidized LDL activates blood platelets through CD36/NOX2–mediated inhibition of the cGMP/protein kinase G signaling cascade. Blood, 125(17), 2693-2703. https://doi.org/10.1182/blood-2014-05-574491

Oxidized low-density lipoprotein (oxLDL) promotes unregulated platelet activation in dyslipidemic disorders. Although oxLDL stimulates activatory signaling, it is unclear how these events drive accelerated thrombosis. Here, we describe a mechanism fo...

Atherothrombosis is associated with platelet hyperactivity. Hypertriglyceridemia and insulin resistance (IR) are features of polycystic ovary syndrome (PCOS). The effect of induced hypertriglyceridemia on IR and platelet function was examined in youn...

Oxidized low-density lipoproteins (oxLDL) generated in the hyperlipidemic state may contribute to unregulated platelet activation during thrombosis. Although the ability of oxLDL to activate platelets is established, the underlying signaling mechanis...

Haemostasis is initiated following blood vessel injury to preclude loss of blood. It involves concerted actions of blood platelets and soluble coagulation factors in forming blood clots at sites of vascular injury. Platelets are recruited from flowin...
