COVID-19: A Mitochondrial Perspective

Coronavirus disease 2019 (COVID-19) is the worst public health crisis of the century. Although we have made tremendous progress in understanding the pathogenesis of this disease, a lot more remains to be learned. Mitochondria appear to be important in COVID-19 pathogenesis because of its role in innate antiviral immunity, as well as inflammation. This article examines pathogenesis of COVID-19 from a mitochondrial perspective and tries to answer some perplexing questions such as why the prognosis is so poor in those with obesity, metabolic syndrome, or type 2 diabetes. Although effective vaccines and antiviral drugs will be the ultimate solution to this crisis, a better understanding of disease mechanisms will open novel avenues for treatment and prevention.
