Analysis of platelet-derived microparticle in dialysis patients.

Platelet and platelet - derived microparticle studies in severe sepsis

Role of P2Y receptor subtypes in platelet-derived microparticle generation.

Microparticles are shed from the platelet membrane upon platelet activation by strong agonists, and they aid in clot formation. As the P2Y1 and the P2Y12 receptors differentially contribute to different platelet functions, we studied the relative contribution of the P2Y1 and P2Y12 receptors to microparticle formation from platelets. The P2Y12 receptor antagonist AR-C 69931MX, but not the P2Y1 r...

Microparticle Formation in Peritoneal Dialysis

BACKGROUND Injury to the mesothelial layer of the peritoneal membrane during peritoneal dialysis (PD) is implicated in loss of ultrafiltration capacity, but there are no validated biomarkers for mesothelial cell injury. Microparticles (MPs) are 0.1 to 1.0 µm membrane vesicles shed from the cell surface following injury and are sensitive markers of tissue damage. Formation of MPs in the peritone...

Comparative Analysis of Serum Levels of Aluminum and Lead in Dialysis Patients, Pre and post Dialysis

Background: Accumulation or deficiency of trace elements can occur in hemodialysis patients and it increases risk of cardiovascular or other organs disorders. Special ions levels such as sodium and bicarbonate in dialysis fluid are accurately regulated but the remaining elements are not regularly measured. Aluminum and lead belong to the biologic performance free heavy metals .They also has a t...

The platelet microparticle proteome.

Platelet-derived microparticles are the most abundant type of microparticle in human blood and contribute to many biologically significant processes. Here, we report the first proteomic analysis of microparticles generated from activated platelets. Using 1D SDS-PAGE and liquid chromatography coupled to a linear ion trap mass spectrometer, the identification of 578 proteins was accomplished usin...
