“…The series of reviews presented here closes with an update on concepts developed to understand the role of blood transfusion as an active regulator of the immune response, and with a manuscript highlighting the potential of the methodological approach of proteomics in the detection and avoidance of adverse drug reactions -a topic with direct relevance to the field of immune regulation induced by blood transfusions: Leo M.G. van de Watering, The Netherlands, discusses different aspects of the immunoregulatory effects of blood transfusions in the light of our current understanding of immune responses [14]. Marc R. Wilkins, Australia, explores recent advances in proteomic technology and how this technology has been applied to the understanding of dose-related, non-doserelated, time-related and withdrawal-based adverse drug reactions [15].…”
