Platelets in Malarial Infection: Protective or Pathological?

, 2020
Platelets play an ambiguous role in a malarial infection. On the one hand, platelets have been implicated adversely in cerebral malaria. They stick to the cerebral endothelium and mediate the adhesion of infected erythrocytes, with the postulated outcome

Atorvastatin-mediated inhibition of prenylation of Rab27b and Rap1a in platelets attenuates their prothrombotic capacity and modulates clot structure

Platelets, 2023
Statins inhibit the mevalonate pathway by impairing protein prenylation via depletion of lipid geranylgeranyl diphosphate (GGPP). Rab27b and Rap1a are small GTPase proteins involved in dense granule secretion, platelet activation, and regulation.

A megakaryocyte with no platelets: Anti-platelet antibodies, apoptosis, and platelet production

Platelets, 2012
Primary immune thrombocytopenia (ITP) and drug-induced thrombocytopenia (DITP) are disorders caused primarily by the presence of anti-platelet auto-antibodies (Abs). Hematologists have traditionally seen thrombocytopenia as the result of increased destruction of Ab-coated platelets by the reticuloendothelial system.

Relationship between thrombocytopenia and prognosis in children with septic shock: a retrospective cohort study

Platelets
Septic shock is a life-threatening disease worldwide often associated with thrombocytopenia. Platelets play a crucial role in bridging the gap between immunity, coagulation, and endothelial cell activation, potentially influencing the course of the ...

Decreased platelet miR-199a-5p level might lead to high on-clopidogrel platelet reactivity in patients with coronary artery disease

Platelets, 2023
Clopidogrel combined with aspirin is widely used in coronary artery disease (CAD) patients, while some patients exhibit high platelet activity when receiving the combined treatment. Current environmental and genetic factors could only explain part of the

Annexin V binding to platelets is agonist, time and temperature dependent

, 2010
Platelets bind annexin V when stimulated with combinations of platelet agonists such as collagen and thrombin. Previous studies have demonstrated significant heterogeneity of platelets binding annexin V.

Appraising non-linear association between pre-diagnostic platelet counts and cancer survival outcomes: observational and genetic analysis

Platelets
Previous studies have reported inconsistent associations between platelet count (PLT) and cancer survival. However, whether there is linear causal effect merits in-depth investigations.

Platelet glycogenolysis is important for energy production and function

Platelets, 2023
Although the presence of glycogen in platelets was established in the 1960s, its importance to specific functions (i.e., activation, secretion, aggregation, and clot contraction) remains unclear.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Release of matrix metalloproteinases-1 and -2, but not -9, from activated platelets measured by enzyme-linked immunosorbent assay

, 2011
Matrix metalloproteinases (MMPs), in particular MMP-9, have been introduced as novel biomarkers in coronary artery disease. Activated platelets are considered to be a major source of the highly elevated levels of MMPs that are detected in serum compared ...
