Microbes Affect The Hallmarks Of Aging: Mitochondrial Dysfunction (Part II)

Posted by in category: biotech/medical

The Hallmarks of Aging are well established, but what is less discussed is the impact of microbes. Viruses, including SARS-CoV-2 and HSV-1 cause mitochondrial dysfunction-more specifically, they cause mitochondria to release some of their DNA, which triggers antiviral immunity. When considering that blood levels of mitochondrial DNA increase during aging, is aging characterized by an increased viral burden?
