止血机制大揭秘!Blood: 磷酸化组学首次揭示血小板GPVI受体的信 …
止血过程中,血小板表面重要粘附受体(GPVI)通过免疫受体酪氨酸激活基序(ITAM)、 Src家族激酶 (SFK)、第二信使信号系统,以磷酸化信号转导驱动的方式,触发瞬时血小板形态变化,介导血小板聚集与止血栓形成。 因此,血小板GPVI信号系统在血管健康与疾病中发挥重要作用。 然而,目前完整描绘血小板凝血调控机制的研究还未见报道。
Platelet GPVI (Glycoprotein VI) and Thrombotic Complications in …
2021年9月9日 · In this review we discuss the emerging evidence for GPVI in venous thrombus formation and leukocyte-dependent thromboinflammation, extending to venous thromboembolism, pulmonary thromboembolism, and cancer metastasis. We also recapitulate indications for circulating soluble GPVI as a biomarker of thrombosis-related complications.
A global proteomics approach identifies novel phosphorylated …
Collagen-related peptide (CRP) stimulates powerful activation of platelets through the GPVI-FcR γ-chain complex. We have combined proteomics and traditional biochemistry approaches to study the proteome of CRP-activated platelets, focusing in detail on tyrosine phosphorylation.
血小板膜糖蛋白Ⅵ(GPⅥ)的研究进展 - 岁月联盟 www.Syue.com
2010年7月12日 · 【摘要】 血小板膜糖蛋白Ⅵ( GPⅥ)是血小板表面重要的胶原受体,能介导血小板与胶原的初期黏附,产生信号转导,提高整合蛋白受体亲合力,引起血小板聚集和血栓形成。 抑制GPⅥ功能可显著抑制胶原诱导的血小板黏附、聚集和血栓形成,故GPⅥ已成为研制新型抗血小板药物的主要靶点。 过去几年中,对血小板和胶原相互作用的研究取得很大进展,本文就GPⅥ的结构,GPⅥ的功能,GPⅥ功能相关因素,GPⅥ与临床等作一综述。 Abstractplatelet …
The role of the adapter molecule SLP-76 in platelet function
2001年10月17日 · Engagement of GPVI is believed to result in Src family kinase-mediated phosphorylation of the tyrosines within the ITAM of Fcγ (Gibbins et al., 1996) providing an excellent docking site for ...
血栓止血实验室-刘俊岭-上海市肿瘤微环境与炎症重点实验室
胶原受体GPVI作为血小板表面一种重要的粘附受体,能够通过与具有免疫受体酪氨酸活化基序的FcRγ-chain偶联,介导胞内活化信号参与血栓止血、炎症等生理病理过程。
Platelet-associated IgAs and impaired GPVI responses in platelets ...
2009年11月11日 · The anti-GPVI antibody JAQ1 induces the irreversible loss of GPVI from circulating platelets in wild-type mice, but not in WIP KO mice that bear high levels of platelet-associated IgAs. Together, the data indicate that platelet-associated IgAs negatively modulate GPVI signaling and function in WIP KO mice.
Rac Inhibition Causes Impaired GPVI Signalling in Human Platelets ...
2022年3月29日 · Rac1-deficient murine platelets have impaired lamellipodia formation, aggregation, and reduced PLCγ2 activation, but not phosphorylation. The objective of our study is to investigate the role of Rac1 in GPVI-dependent …

Functional significance of the platelet immune receptors GPVI and …
In this Review, we discuss the physiological and pathological roles of CLEC-2 and GPVI and their potential as targets in thrombosis and thrombo-inflammatory disorders (i.e., disorders in which inflammation plays a critical role in the ensuing thrombosis) relative to current antiplatelet drugs.
