Rapid ubiquitination of Syk following GPVI activation in platelets [PDF]

open access: yesBlood, 2005
AbstractSpleen tyrosine kinase (Syk) activation is a key intermediate step in the activation of platelets by the physiologic agonist collagen. We have found that Syk is rapidly ubiquitinated upon activation of platelets by collagen, collagen-related peptide (CRP), and convulxin.

A Critical Review on BH3 Mimetic Drugs and the Treatment of Cancer‐Associated Thrombosis (CAT): A Proposed Design for a Drug Delivery System Capable of Simultaneously Targeting Tumor Cells and Activated Platelets

open access: yesCancer Medicine, Volume 14, Issue 18, September 2025.
Targeting Cancer associated thrombosis (CAT): The left panel (A) shows cancer‐associated thrombosis with activated platelets expressing αIIbβ3 in close contact with tumoral vasculature expressing αvβ3 integrin, where both cells release a significant amount of thrombin.

Model systems for platelet receptor shedding

open access: yesPlatelets, 2017
Platelet adhesion and aggregation at sites of vascular injury are crucial for hemostasis; however, under pathological conditions, they can cause myocardial infarction and stroke.

Pharmacological actions of nobiletin in the modulation of platelet function [PDF]

open access: yes, 2015

Gene Targeting Implicates Cdc42 GTPase in GPVI and Non-GPVI Mediated Platelet Filopodia Formation, Secretion and Aggregation

open access: yesPLoS ONE, 2011
Cdc42 and Rac1, members of the Rho family of small GTPases, play critical roles in actin cytoskeleton regulation. We have shown previously that Rac1 is involved in regulation of platelet secretion and aggregation. However, the role of Cdc42 in platelet activation remains controversial. This study was undertaken to better understand the role of Cdc42 in

Basic mechanisms of platelet receptor shedding

open access: yesPlatelets, 2017
Proteolytic shedding of the extracellular ectodomain of platelet receptors provides a key mechanism for irreversible loss of ligand-binding capacity, and for regulating platelet function in health and disease.

Targeting GPVI

open access: yes, 2023
Platelets are blood cells that prevent the loss of extensive blood volumes, but also contribute to arterial thrombosis. After a vessel is injured, platelets become activated by the exposed collagen and aggregate together, forming a thrombus. Whilst this is a crucial process in hemostasis, platelets also become activated due to rupture of an ...

Activation of GPVI by collagen is regulated by α2β1 and secondary mediators [PDF]

open access: yesJournal of Thrombosis and Haemostasis, 2003
We have compared the roles of adenosine diphosphate (ADP), thromboxanes and the integrin alpha(2)beta(1) in the activation of washed platelets by collagen in the presence of the alpha(IIb)beta(3) antagonist lotrafiban. The stimulation of protein tyrosine phosphorylation by a collagen suspension is markedly delayed in the presence of the above ...

Role of Gut‐Derived Endotoxins in Porto‐Sinusoidal Vascular Disorder: Comparison Between patients with and without portal hypertension

open access: yesLiver International, Volume 45, Issue 9, September 2025.
ABSTRACT Background Etiopathogenesis of porto‐sinusoidal vascular disorder (PSVD) is poorly known. The present study aimed to investigate alterations in gut barrier, bacterial translocation, and pro‐aggregating/pro‐coagulant state and their relationship with liver injury in patients with PSVD without portal hypertension (PH−) in comparison with PSVD ...

Restoration of responsiveness of phospholipase Cγ2-deficient platelets by enforced expression of phospholipase Cγ1. [PDF]

open access: yesPLoS ONE, 2015
Receptor-mediated platelet activation requires phospholipase C (PLC) activity to elevate intracellular calcium and induce actin cytoskeleton reorganization. PLCs are classified into structurally distinct β, γ, δ, ε, ζ, and η isoforms.
