SARS-CoV-2, Oxidative Stress, and Mitochondrial Damage in Immune Cells

Study Title: SARS-CoV-2 induces mitochondrial dysfunction and cell death by oxidative stress/inflammation in leukocytes of COVID-19 patients

Citation: De la Cruz-Enríquez et al., 2021 · Free Radical Research

What the Study Found: SARS-CoV-2 directly causes mitochondrial dysfunction and cell death in leukocytes through oxidative stress and inflammatory pathways. Infected patients showed severely impaired mitochondrial respiration and elevated ROS in immune cells. The study links this mitochondrial damage to the systemic inflammation seen in COVID-19.

What this means in real life: When mitochondria in immune cells are damaged by the virus, the body’s defense system itself runs out of energy and becomes inflammatory. This research shows exactly how SARS-CoV-2 sabotages cellular energy production, helping explain the fatigue and long-term effects of COVID. Protecting mitochondrial health may be one of the most important ways to support immune recovery and prevent prolonged symptoms.
