MetabolomicsDifferential Metabolomic Biomarkers Analysis of Apheresis Platelet Storage Based on Machine Learning Models

Platelet storage lesion (PSL) is a critical factor limiting the efficacy of platelet transfusion. Although hypothermic (4°C) storage is considered beneficial for maintaining platelet function, the underlying mechanisms of systemic metabolic reprogramming remain incompletely understood. This study...

ProteomicsA Comprehensive Proteomics Study on Platelet Concentrates: Platelet Proteome, Storage Time and Mirasol Pathogen Reduction Technology
Platelet concentrates (PCs) represent a blood transfusion product with a major concern for safety as their storage temperature (20-24ºC) allows bacterial growth, and their maximum storage time period (less than a week) precludes complete microbiological testing. Pathogen inactivation technologies (P...

ProteomicsDeciphering changes to human platelet proteome and degradome during storage before transfusion
Proteases, and specifically metalloproteinases, have been linked to the loss of platelet function during storage before transfusion, albeit the mechanism remains unknown. We used a dedicated N-terminomics technique, multiplex iTRAQ-TAILS (Terminal Amine Isotope Labeling of Substrates), to characteri...

ProteomicsLabel free quantitative mass spectrometry identifies platelet degranulation as an early event during platelet storage
Shelf life of platelet concentrates (PCs) is limited to up to 7 days due to loss of platelet functionality during storage, commonly referred to as the platelet storage lesion (PSL). To get more insight into the development of the PSL, we used label free quantitative mass spectrometry to identify cha...

MetabolomicsInhibition of stress resilience and adult hippocampal neurogenesis by platelet-derived LPA16:0 in anxiety

Anxiety is an aggravating comorbidity of many psychiatric disorders that is often underdiagnosed and undertreated, and little is known on the mechanisms underlying its regulation. Here, we find that serum LPA16:0 abundance increases with trait anxiety in both humans and mice; while high LPA16:0 l...

ProteomicsProteomic analysis of extracellular vesicles derived from platelet concentrates treated with Mirasol® identifies biomarkers of platelet storage lesion
In blood banks, platelets are stored until 7 days after a pathogen reduction technology (PRT) treatment, Mirasol® (vitamin B2 plus UVB light) in the present case. The storage time under these conditions may have an impact on platelets and their releasate leading to potential adverse reactions follow...

TranscriptomicsNew molecular insights into modulation of platelet reactivity in aspirin-treated patients using a network-based approach [Affymetrix]
Platelet reactivity (PR) in cardiovascular (CV) patients is variable between individuals and modulates clinical outcome. However, the determinants of platelet reactivity are largely unknown. Integration of data derived from high-throughput omics technologies may yield novel insights into the molecul...

ProteomicsPlatelet proteome dynamics in hibernating 13-lined ground squirrels
Hibernating mammals undergo a dramatic drop in temperature and blood flow during torpor and must suppress hemostasis to avoid stasis blood clotting. In addition, cold storage of most mammalian platelets induces cold storage lesions, resulting in rapid clearance following transfusion. 13-lined ground...

ProteomicsPlatelet proteomics profiling in transfusion adverse events
Blood platelets destined for transfusion release panoply of molecules during preparation and storage. The leukoreduction process made the transfusion safer but did not completely abolish the adverse events. The rationale is to study the proteome profile of platelet components SDA-PC (platelet pellet...
