PLATELET PHAGOCYTOSIS AND AGGREGATION [PDF]

open access: bronzeThe Journal of Cell Biology, 1965
The addition of latex particles to native (no anticoagulant) or citrated human platelet-rich plasma (PRP), or to a once-washed platelet suspension causes platelet aggregation. This aggregation is associated with phagocytosis of the latex particles by the platelets and appears to be due to release of adenosine diphosphate (ADP) from the platelets ...

A review of natural compounds to regulate platelet aggregation: molecular mechanism and research advance [PDF]

open access: yesFrontiers in Pharmacology
Platelets are a class of blood cells exfoliated from bone marrow megakaryocytes and important participants in the blood. Aggregation is a prominent part of the platelets involved in the hemostasis process, regulated by multiple signaling pathways ...

Physiological platelet aggregation assay to mitigate drug-induced thrombocytopenia using a microphysiological system [PDF]

open access: yesScientific Reports
Developing a reliable method to predict thrombocytopenia is imperative in drug discovery. Here, we establish an assay using a microphysiological system (MPS) to recapitulate the in-vivo mechanisms of platelet aggregation and adhesion.

The Ratio of ADP- to TRAP-Induced Platelet Aggregation Quantifies P2Y12-Dependent Platelet Inhibition Independently of the Platelet Count. [PDF]

open access: yesPLoS ONE, 2016
This study aimed to assess the association of clinical factors with P2Y12-dependent platelet inhibition as monitored by the ratio of ADP- to TRAP-induced platelet aggregation and conventional ADP-induced aggregation, respectively.Controversial findings ...

Correlation Between P-Selectin Level and Platelet Aggregation in Cerebral Venous Sinus Thrombosis Patients

open access: yesMajalah Kedokteran Bandung, 2023
One of the causes of cerebral venous sinus thrombosis (CVST) is platelet hyperactivity. Adhesion and secretion are the beginning of platelet activation, which is indicated by a change in the Platelet-selectin (P-selectin) level.

Quinonoid dihydropteridine reductase, a tetrahydrobiopterin-recycling enzyme, contributes to 5-hydroxytryptamine-associated platelet aggregation in mice

open access: yesJournal of Pharmacological Sciences, 2022
Quinonoid dihydropteridine reductase (QDPR) regenerates tetrahydrobiopterin (BH4), which is an essential cofactor for catecholamine and serotonin (5-hydroxytryptamine, 5-HT) biosynthesis.
