Antioxidant synthetic peptides counteracting hyperglycaemia induced endothelial cell dysfunction

In the issue of International Journal of Cardiology, Hemling P. et al. describe that the impairment of thioredoxin (TRX) activity is partially responsible for reactive oxygen species (ROS) accumulation in hyperglycaemic endothelial cells (EC). Interestingly, authors extend this finding to placental arterial EC where the employment of TRX synthetic peptides is able to restore physiological levels of ROS and subsequent improvement of the VEGF-A...
