Platelet-Activating Factor-Induced Reduction in Contact Hypersensitivity Responses Is Mediated by Mast Cells via Cyclooxygenase-2-Dependent Mechanisms [PDF]

, 2018
Platelet-activating factor (PAF) stimulates numerous cell types via activation of the G protein-coupled PAF receptor (PAFR). PAFR activation not only induces acute proinflammatory responses, but it also induces delayed systemic immunosuppressive effects ...

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.

Intravascular tissue factor initiates coagulation via circulating microvesicles and platelets [PDF]

, 2003
Although tissue factor (TF), the principial initiator of physiological coagulation and pathological thrombosis, has recently been proposed to be present in human blood, the functional significance and location of the intravascular TF is unknown.

EPHB2 regulates platelet activation [PDF]

Blood, 2018
Historically, detailed studies of rare congenital platelet defects have provided unique insights into key proteins involved in human platelet function. In this issue of Blood, Berrou et al use advanced genomic sequencing/functional analysis to identify a novel role for ephrin transmembrane receptor subclass B2 (EPHB2) in regulating platelet activation ...

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.

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Platelet activation determines angiopoietin-1 and VEGF levels in malaria: implications for their use as biomarkers. [PDF]

PLoS ONE, 2014
INTRODUCTION: The angiogenic proteins angiopoietin (Ang)-1, Ang-2 and vascular endothelial growth factor (VEGF) are regulators of endothelial inflammation and integrity.

CD40 is constitutively expressed on platelets and provides a novel mechanism for platelet activation [PDF]

, 2003
CD40 is a 48-kDa phosphorylated transmembrane glycoprotein belonging to the TNF receptor superfamily. CD40 has been demonstrated on a range of cell types, and it has an important role in adaptive immunity and inflammation.

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.

Platelet activation marker

Japanese Journal of Thrombosis and Hemostasis, 2007
Atherosclerosis is the leading cause of death in patients with diabetes mellitus, increasing mortality in all forms of the disease. Classical risk factors, including hyperlipidemia, hypertension and obesity, do not completely account for the increased incidence of atherosclerosis in diabetes. Some platelet activation markers such as CD62P, CD63, PAC-1,
