Zusammenfassung:Continued efforts to reduce the risk of transfusion-transmitted infections (TTIs) through blood and blood components led to the development of ultraviolet (UV) light irradiation technologies known as pathogen reduction technologies (PRT) to enhance blood safety. While these PRTs demonstrate germicidal efficiency, it is generally accepted that these photoinactivation techniques have limitations as they employ treatment conditions shown to compromise the quality of the blood components. During ex vivo storage, platelets having mitochondria for energy production suffer most from the consequences of UV irradiation. Recently, application of visible violet-blue light in the 400–470 nm wavelength range has been identified as a relatively more compatible alternative to UV light. Hence, in this report, we evaluated 405 nm light-treated platelets to assess alterations in energy utilization by measuring different mitochondrial bioenergetic parameters, glycolytic flux, and reactive oxygen species (ROS). Furthermore, we employed untargeted data-independent acquisition mass spectrometry to characterize platelet proteomic differences in protein regulation after the light treatment. Overall, our analyses demonstrate that ex vivo treatment of human platelets with antimicrobial 405 nm violet-blue light leads to mitochondrial metabolic reprogramming to survive the treatment, and alters a fraction of platelet proteome. •UV light-based pathogen reduction technologies (PRTs) for stored blood and blood components harm quality and function of the treated products•405 nm light in the visible-spectra is an effective antimicrobial agent and has the potential to be safer on treated products.•405 nm light dose of 270 J/cm2 is sufficient to reduce pathogens while not harming the quality of the treated blood component(s).•405 nm light-treated platelets demonstrate minimal proteomic alterations.
