Iloprost Concentration‐Dependently Attenuates Platelet Function and Apoptosis by Elevating PKA Activity

open access: yesJournal of Cellular and Molecular Medicine, Volume 29, Issue 3, February 2025.
ABSTRACT Iloprost, a prostacyclin (PGI2) analogue, stimulates the IP receptor (PTGIR) to interact with the Gsα β/γ complex, leading to the activation of adenylate cyclase, which enzyme produces the second messenger cAMP. Elevation in cAMP triggers intracellular signalling events and regulates a wide variety of cellular activities.

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

Modulation of Haemostatic Balance in Combined von Willebrand Disease and Antithrombin Deficiency: A Comprehensive Family Study

open access: yesHaemophilia, Volume 31, Issue 1, Page 140-147, January 2025.
ABSTRACT Introduction Maintaining the balance between procoagulant and anticoagulant factors is essential for effective haemostasis. Emerging evidence suggests a modulation of bleeding tendency by factors in the anticoagulant and fibrinolytic systems. Aim This study investigates the clinical and laboratory characteristics of a family with combined von ...

Small but mighty: Platelets as multifunctional architects of tumor metastasis and immune regulation

open access: yesMedComm – Future Medicine, Volume 3, Issue 4, December 2024.
Platelets are crucial in cancer progression and immune response, impacting tumor metastasis and diagnosis while offering potential targets for antitumor therapies. Abstract Platelets play an irreplaceable role in hemostasis and wound healing. However, beyond these classical roles, as the smallest anucleate cells in the blood stream, they are crucial ...

Effect of Shear Stress on Platelet Activation via the Glycoprotein VI Receptor [PDF]

open access: yes, 2002
Cardiovascular diseases are the nation\u27s leading cause of death. Such diseases are caused by platelet response to collagen especially in the event of vascular injury leading to thrombosis.

Hemin‐induced platelet activation is regulated by the ACKR3 chemokine surface receptor and has implications for passivation of vulnerable atherosclerotic plaques

open access: yesThe FEBS Journal, Volume 291, Issue 24, Page 5420-5434, December 2024.
Intraplaque hemorrhages (IPH) result in hemolysis and liberation of iron‐containing heme and its oxidized metabolite, hemin. Hemin activates platelets and has strong prothrombotic activity. Here, we show that agonism of the atypical chemokine receptor 3 (ACKR3) inhibits hemin‐induced platelet activation.

Exacerbation of glycoprotein VI-dependent platelet responses in a rhesus monkey model of type 1 diabetes [PDF]

open access: yes, 2018
Thrombosis is a life-threatening complication of diabetes. Platelet reactivity is crucial to thrombus formation, particularly in arterial vessels and in thrombotic complications causing myocardial infarction or ischaemic stroke, but diabetic patients ...

The effects of signal transducer and activator of transcription three mutations on human platelets

open access: yesPlatelets, 2018
Involvement of signal transducer and activator of transcription 3 (STAT3) in inflammation is well known. Recently, a role for STAT3 in platelet activation and platelet production has been suggested.

TNF Receptor-Associated Factor 4 (TRAF4) is a novel binding partner of glycoprotein Ib and glycoprotein VI in human platelets. [PDF]

open access: yes, 2010
Background: Reactive oxygen species generation is one consequence of ligand engagement of platelet glycoprotein (GP) receptors GPIb-IX-V and GPVI, which bind VWF/collagen and initiate thrombosis at arterial shear, however the precise molecular mechanism ...
