Acetylcholine Inhibits Platelet Activation [PDF]

The Journal of Pharmacology and Experimental Therapeutics, 2019
Platelets are key mediators of thrombosis. Many agonists of platelet activation are known, but fewer endogenous inhibitors of platelets, such as prostacyclin and nitric oxide (NO), have been identified. Acetylcholinesterase inhibitors, such as donepezil, can cause bleeding in patients, but the underlying mechanisms are not well understood.

Endogenous SIRT6 in platelets negatively regulates platelet activation and thrombosis

Frontiers 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 ...

Vibro-Acoustic Platelet Activation: An Additive Mechanism of Prothrombosis with Applicability to Snoring and Obstructive Sleep Apnea

Bioengineering, 2023
Introduction: Obstructive sleep apnea (OSA) and loud snoring are conditions with increased cardiovascular risk and notably an association with stroke.

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

Platelets, 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.

Impact of diabetes on platelet activation in different manifestations of atherosclerosis

Swiss Medical Weekly, 2013
BACKGROUND: Atherosclerosis affects many patients with type 2 diabetes. Both are associated with platelet activation, but it remains unclear how diabetes contributes to, or even enhances, platelet activation in patients with atherosclerosis.

Synergistic inhibitory effects of clopidogrel and rivaroxaban on platelet function and platelet‐dependent thrombin generation in cats

Journal of Veterinary Internal Medicine, 2023
Background Dual antithrombotic treatment (DAT) with clopidogrel and rivaroxaban sometimes is prescribed to cats with hypertrophic cardiomyopathy at risk of thromboembolism.

Underlying mechanism and specific prevention of hemolysis-induced platelet activation

Platelets, 2017
Thromboembolic complications significantly impair the outcome of hemolytic disorders. We hypothesized that red cell adenosine diphosphate (ADP) release results in significant platelet activation in hemolysis and that this prothrombotic state can be ...

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 ...

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.

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.
