Introduction: Mt DNA (DAMPs) plays a key modulatory role in immune cells and may also mediate a variety of adverse transfusion reactions.
Material and method: The cross-sectional study was performed on 22 (PRP) and 14 (SDP) between February 2019 and 2020. mtDNA DAMPs by quantitative real-time PCR was assessed on days 1, 3, and 5 of platelets storage. The data was entered in REST 2009 software, and the amount of fold change was calculated. Multiple t tests were also used.
Results: The mtDNA DAMPs fold change in SDP on days 1-3, 1.3 times, on days 3-5, 1.5 times, and on days 1-5, 2.1 times increased. The fold change on days 1-3, 0.8 times, on days 3-5, 0.6 times, and on days 1-5, 0.49 times decreased in PRP products.
Conclusion: The method of preparation and processing can affect mtDNA DAMPs fold changes.
