Platelet integrin α 2 β 1 is an important collagen receptor on the platelet membrane. Although present in a much lower concentration than α IIb β 3 or the GPIb complex, this receptor has also been shown to be a target autoantigen in 10% … WebFeb 23, 2024 · Platelet glycoprotein (GP) Ia/IIa of the coding region of the platelet receptor for collagen is known as a key member of the integrin family. Platelet GP Ia/IIa can mediate interactions among cells or between cells and the extracellular matrix [10–12]. These proteins can aid white blood cells and platelets in adhering to the vascular endothelium.
WebJan 1, 2005 · Collagen receptor deficiency has been described in several unrelated patients. It has become clear that there are two distinct receptors on the platelet … WebExposed collagen at a vascular damage site can activate platelets via collagen receptor GPVI and GPIa and bind shear-stretched multimeric VWF proteins, which subsequently interact with the platelet surface receptor, GPIb-V-IX. Upon full activation, platelets can aggregate by binding to fibrinogen through activated GPIIb-GPIIIa receptors. ...

WebSep 5, 2024 · Platelet adhesion is the process by which platelets attach to the exposed subendothelial vWF. Post vascular damage, platelets begin to roll along vessel walls and adhere to areas of exposed subendothelial collagen and vWF.
