摘要

BACKGROUND: Platelet transfusions are safe but can nevertheless cause serious adverse reactions (SARs). This study investigated the effects of platelet biological response modifiers (BRMs) that accumulate during storage and are commonly associated with transfusion adverse reactions. STUDY DESIGN AND METHODS: Endothelial cells (ECs), that is, EA.hy926, were exposed in vitro to supernatants of platelet components (PCs) that had been either implicated or not in SARs. The EC Biology RT2 Profiler PCR Array was used at the same time to study 84 genes related to functions of ECs. Soluble cytokines and surface expression of EC markers were determined by Luminex/enzyme-linked immunosorbent assay technology and flow cytometry, respectively. Apoptosis and scratch wound assays were performed using IncuCyte technology. RESULTS: In vitro exposure of EA.hy926 monolayers with Day 0, 1-2, and 3-4 stored PC supernatants resulted in decreases in surface expression of markers of ECs. There was differential production of soluble BRMs in the tested cell line. Exposure to the supernatants of PCs that had been implicated in SARs showed a significant difference in the expression of the EC surface markers. EC mediators also responded differently when exposed to PC supernatants of different storage times and PCs involved in SARs. CONCLUSION: PC supernatants collected at Day 1-2 activate fewer cell lines of ECs compared with supernatants collected at Day 3-4. Moreover, PC supernatants involved in SARs appear to alter EC activation compared with the control and storage length.
