Age associated non-linear regulation of redox homeostasis in the anucleate platelet: Implications for CVD risk patients.

We report a novel age associated, non-linear redox regulation in platelets in both humans and mice. In advanced age, there occurs an adaptive increase in platelet antioxidants, reducing the intracellular ROS and leading to a healthier platelet phenotype. Clinically, our results advocate the use of less aggressive antiplatelet therapies for CVD in the elderly population. FUND: Study funded by NIH-NHLBI, RO1-HL122815 and RO1-HL115247.
