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

Platelets and infection — an emerging role of platelets in viral infection

Frontiers in Immunology, 2014
Platelets are anucleate blood cells that play a crucial role in the maintenance of hemostasis. While platelet activation and elevated platelet counts (thrombocytosis) are associated with increased risk of thrombotic complications, low platelet counts ...

The platelet transcriptome and proteome in Alzheimer’s disease and aging: an exploratory cross-sectional study

Frontiers in Molecular Biosciences, 2023
Introduction: Alzheimer’s disease (AD) and aging are associated with platelet hyperactivity. However, the mechanisms underlying abnormal platelet function in AD and aging are yet poorly understood.Methods: To explore the molecular profile of AD and aged ...

Platelet Toll-like receptor expression and activation induced by lipopolysaccharide and sepsis

Platelets, 2019
Platelets and Toll-like receptor (TLR) signalling play a role in the immune response during sepsis. Although preclinical knowledge about the role of platelet TLR signalling is increasing, data during human sepsis are less abundant.

Platelet activation in adult HIV-infected patients on antiretroviral therapy: a systematic review and meta-analysis

BMC Medicine, 2020
Background Antiretroviral therapy (ART) alters platelet reactivity, and as a consequence, patients living with HIV may be at an increased risk of cardiovascular disease (CVD).

The tyrosine phosphatase CD148 is an essential positive regulator of platelet activation and thrombosis [PDF]

, 2009
Platelets play a fundamental role in hemostasis and thrombosis. They are also involved in pathologic conditions resulting from blocked blood vessels, including myocardial infarction and ischemic stroke.

Cobimetinib and trametinib inhibit platelet MEK but do not cause platelet dysfunction [PDF]

, 2018
The MEK inhibitors cobimetinib and trametinib are used in combination with BRAF inhibitors to treat metastatic melanoma but increase rates of hemorrhage relative to BRAF inhibitors alone.

A subset of anti-HLA antibodies induces FcγRIIa-dependent platelet activation

Haematologica, 2018
HLA antibodies are associated with refractoriness to platelet transfusion, leading to rapid platelet clearance, sometimes coinciding with clinical side effects such as fever and chills.

Functional redundancy between RAP1 isoforms in murine platelet production and function [PDF]

, 2018
RAP GTPases, important regulators of cellular adhesion, are abundant signaling molecules in the platelet/megakaryocytic lineage. However, mice lacking the predominant isoform, RAP1B, display a partial platelet integrin activation defect and have a ...
