"Link Between Faulty DNA Disposal and Inflammation Discovered"

Researchers at the Salk Institute and UC San Diego have identified a novel mechanism for removing malfunctioning mitochondrial DNA (mtDNA) from within mitochondria, which, when leaked into the cell, triggers an immune response leading to inflammation. The study sheds light on how mtDNA escapes mitochondria and activates the innate immune system, offering potential targets for therapeutics to mitigate inflammation associated with aging and diseases such as lupus and rheumatoid arthritis. The findings provide insights into cellular pathways and mechanisms that could be targeted for therapeutic interventions to prevent inflammation caused by misplaced mtDNA.
