Opposing Effects of Platelet-Activating Factor and Lyso-Platelet-Activating Factor on Neutrophil and Platelet Activation

open access: yesMolecular Pharmacology, 2009
Platelet-activating factor (PAF) is a potent, bioactive phospholipid that acts on multiple cells and tissues through its G protein-coupled receptor (GPCR). PAF is not stored but is rapidly generated via enzymatic acetylation of the precursor 1-O-hexadecyl-2-hydroxy-sn-glycero-3-phosphocholine (lysoPAF). The bioactivity of PAF is effectively and tightly

Interleukin-6 and asymmetric dimethylarginine are associated with platelet activation after percutaneous angioplasty with stent implantation. [PDF]

open access: yesPLoS ONE, 2015
Data linking in vivo platelet activation with inflammation and cardiovascular risk factors are scarce. Moreover, the interrelation between endothelial dysfunction as early marker of atherosclerosis and platelet activation has not been studied, so far. We

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

open access: yesFrontiers 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

open access: yesFrontiers 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

open access: yesPlatelets, 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

open access: yesBMC 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).

PD-L1 Regulates Platelet Activation and Thrombosis via Caspase-3/GSDME Pathway

open access: yesFrontiers in Pharmacology, 2022
Platelets play a central role in hemostasis and thrombosis, regulating the occurrence and development of thrombotic diseases, including ischemic stroke. Programmed death ligand 1 (PD-L1) has recently been detected in platelet, while the function of PD-L1

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

open access: yesHaematologica, 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.

Endogenous SIRT6 in platelets negatively regulates platelet activation and thrombosis

open access: yesFrontiers in Pharmacology, 2023
Thromboembolism resulting from platelet dysfunction constitutes a significant contributor to the development of cardiovascular disease. Sirtuin 6 (SIRT6), an essential NAD+-dependent enzyme, has been linked to arterial thrombosis when absent in ...

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

open access: yesPlatelets, 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.
