糖蛋白Ib-IX(GPIb-IX)复合物介导初始血小板与固定在内皮下基质和内皮表面上的血管性血友病因子(VWF)的粘附,并传递VWF结合诱导的信号以刺激血小板活化。GPIb-IX还作为机械传感器的一部分发挥作用,将通过VWF结合接收的机械力转化为细胞内信号,从而大大增强血小板活化。凝血酶与GPIb-IX的结合与蛋白酶激活的受体协同启动GPIb-IX信号传导,以协同刺激血小板对低剂量凝血酶的应答。GPIb-IX信号传导也可能在与其他GPIb-IX配体(如白细胞整合素αMβ2和红细胞来源的脑信号蛋白7A)结合后发生,从而导致血栓炎症。GPIb-IX信号传导需要GPIb-IX和14-3-3蛋白质的胞质结构域之间的相互作用,并且通过Src家族激酶、Rho家族的小GTP酶、磷酸肌醇3-激酶-Akt-cGMP-促分裂原活化蛋白激酶和LIM激酶1信号传导途径介导,导致钙动员、整联蛋白活化和颗粒分泌。本文综述了目前对GPIb-IX信号的理解。
The glycoprotein Ib–IX (GPIb-IX) complex mediates initial platelet adhesion to von Willebrand factor (VWF) immobilized on subendothelial matrix and endothelial surfaces, and transmits VWF binding-induced signals to stimulate platelet activation. GPIb-IX also functions as part of a mechanosensor to convert mechanical force received via VWF binding into intracellular signals, thereby greatly enhancing platelet activation. Thrombin binding to GPIb-IX initiates GPIb-IX signaling cooperatively with protease-activated receptors to synergistically stimulate the platelet response to low dose thrombin. GPIb-IX signaling may also occur following the binding of other GPIb-IX ligands such as leukocyte integrin αMβ2 and red cell-derived semaphorin 7A, contributing to thrombo-inflammation. GPIb-IX signaling requires the interaction between the cytoplasmic domains of GPIb-IX and 14-3-3 protein and is mediated through Src family kinases, the Rho family of small GTPases, phosphoinositide 3-kinase-Akt-cGMP-mitogen-activated protein kinase, and LIM kinase 1 signaling pathways, leading to calcium mobilization, integrin activation and granule secretion. This review summarizes the current understanding of GPIb-IX signaling.
