HEMOSTASIS, THROMBOSIS, AND VASCULAR BIOLOGY Moderation of the platelet releasate response by aspirin1 Scripps Research Institute, Department of Cell Biology, La Jolla, CA; 2 School of Biomolecular & Biomedical Science, Conway Institute, University College Dublin, Ireland; 3 School of Medicine and Medical Science, University College Dublin, Ireland; 4 Proteome Research Center, Conway Institute, University College Dublin, Ireland Modulation of the proteins released during activation is one mechanism whereby aspirin may influence platelet-mediated human disease. We investigated the effect of aspirin on the platelet releasate using mass spectrometry and found that different agonists evoked different releasate profiles, with aspirin having a general moderating effect on the amount of protein released regardless of the agonist. These observations were confirmed for several cytokines using an antibody array approach.
