Detection of Induction of Mitochondrial Oxidative Stress by Nanoparticles in T Cells Using MitoSOX Red Dye

Abstract

The induction of oxidative stress by engineered nanomaterials has been associated with cytotoxic and inflammatory responses, damaging healthy cells and tissues. In contrast, when directed against cancer and autoinflammatory diseases, some nanomaterials inducing oxidative stress have also been reported as potential therapies for these disorders. Therefore, studying oxidative stress has become a popular tool not only in toxicology and immunotoxicology but in other areas of biology as well, including those related to developing novel therapies. Total oxidative stress may result from multiple cellular organelles. The protocol described herein allows for the analysis of oxidative stress in mitochondria.
