Tirofiban potentiates agonist-induced platelet activation and degranulation, despite effectively inhibiting aggregation

Platelets, 2022
We aimed to investigate the effects of integrin αIIbβ3 inhibitor tirofiban on hallmarks of platelet activation, degranulation, and aggregation during its use to analyze activated but non-complexed platelets via flow cytometry.

Potentiation of thrombus instability: a contributory mechanism to the effectiveness of antithrombotic medications [PDF]

, 2018
© The Author(s) 2018The stability of an arterial thrombus, determined by its structure and ability to resist endogenous fibrinolysis, is a major determinant of the extent of infarction that results from coronary or cerebrovascular thrombosis.

Effect of phosphodiesterase inhibitors on platelet function

Biochemistry and Biophysics Reports
Phosphodiesterase enzymes (PDEs) play a pivotal role in regulating platelet activity by modulating intracellular levels of cAMP and cGMP. Modulation of PDE-2, -3 and -5 activity by suitable inhibitors has been found to reduce platelet activity, and thus ...

cGMP-dependent protein kinase regulates Rap1 signaling in platelets : poster presentation [PDF]

, 2007
cGMP- and cAMP-dependent protein kinases (cGK and cAK) mediate the inhibitory effects of endothelium-derived messenger molecules nitric oxide and prostacyclin on platelets.

Anti-HLA antibodies with complementary and synergistic interaction geometries promote classical complement activation on platelets

Haematologica, 2019
High titers of HLA antibodies are associated with platelet refractoriness, causing poor platelet increments after transfusions in a subset of patients with HLA antibodies.

The actin binding proteins cortactin and HS1 are dispensable for platelet actin nodule and megakaryocyte podosome formation [PDF]

, 2016
A dynamic, properly organised actin cytoskeleton is critical for the production and haemostatic function of platelets. The Wiskott Aldrich Syndrome protein (WASp) and Actin-Related Proteins 2 & 3 Complex (Arp2/3 complex) are critical mediators of ...

Platelet activation via dynamic conformational changes of von Willebrand factor under shear.

PLoS ONE, 2020
Shear-induced conformational changes of von Willebrand factor (VWF) play an important role in platelet activation. A novel approach describing VWF unfolding on the platelet surface under dynamic shear stress is proposed.

Platelet kinetics in the pulmonary microcirculation in vivo assessed by intravital microscopy [PDF]

, 2002
Growing evidence supports the substantial pathophysiological impact of platelets on the development of acute lung injury. Methods for studying these cellular mechanisms in vivo are not present yet.

Paradigm of biased PAR1 (protease-activated receptor-1) activation and inhibition in endothelial cells dissected by phosphoproteomics [PDF]

, 2017
Thrombin is the key serine protease of the coagulation cascade and mediates cellular responses by activation of PARs (protease-activated receptors). The predominant thrombin receptor is PAR1, and in endothelial cells (ECs), thrombin dynamically regulates

Germline TP53 Mutations Causing Diamond–Blackfan Anemia: A French Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Diamond–Blackfan anemia is a rare congenital erythroblastopenia typically caused by mutations in ribosomal protein genes. Recently, gain‐of‐function mutations in TP53 have been identified as a novel cause of Diamond–Blackfan anemia. We report two French patients who both harbored a heterozygous TP53 deletion (NM_000546.5: c.1077delA; p ...
