Evaluation of microRNAs; mir223, mir222 and mir92a levels in the Platelet-derived microparticles in the Platelet concentrates produced by Platelet Rich Plasma method during storage
Abstract Background and Objectives Platelets release microparticles containing cellular components, including microRNAs, during storage. Assessment of these microRNAs is one of the markers for evaluation of platelet storage lesions. The aim of the present study was to evaluate the level of changes in the expression of mir-223, mir-92a and mir-222 during storage in platelets prepared by platele...
متن کاملAn Overview on Platelet-derived Microparticles in Platelet Concentrates: blood collection, method preparation and storage
Preparations of platelet concentrates (PCs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (PMPs) with high coagulant activity that may change platelet efficacy and safety issues. High shear stress could cause shedding of PMPs from the platelet plasma membrane, platelet aggregation, and activation of the co...
متن کاملFlow Cytometric Measurement of CD41/CD61 and CD42b Platelet Receptors and Clotting Assay of Platelet Factor 3 During Long Term-Storage of Platelet Concentrates
Background: The purpose of the present in vitro study was to evaluate the effect of long term storage of conventional platelet concentrates (PCs) on major platelet receptors CD42b and CD41/CD61 by flow cytometry method and also measuring the overall platelet procoagulant activity status using platelet factor 3 (PF3) assay. Materials and Methods: Six random units of conventional platelet conce...
متن کاملCalcium-dependent proteolysis of actin during storage of platelet concentrates.
In an ongoing study of the changes that occur in platelet concentrates during storage, we investigated two 28-26-Kd proteins designated SP-1 and SP-2, respectively, which increase markedly during blood-bank storage of platelet concentrates at room temperature. Formation of SP-1 and SP-2 was inhibited by storage at 4 degrees C as well as by treatment of the concentrates with leupeptin, N-ethylma...
متن کاملEvaluation of platelet storage lesions in platelet concentrates stored for seven days.
BACKGROUND & OBJECTIVES Platelet storage lesions (PSL) are detrimental to the post transfusion functional capacity of platelets. As EDTA enhances the storage-induced changes, changes in platelet indices with and without EDTA incubation are promising new tests to monitor the PSL. The present study was undertaken to monitor the PSL in 40 units of pooled platelet concentrates harvested by platelet...
