Viral science news: Autoimmune thyroiditis has long puzzled researchers with how mitochondrial material sparks an inflammatory cascade that ultimately damages thyroid tissue. A new study now points to an internal quality-control process—mitophagy—as a crucial brake on this pathway, revealing that cells can prevent excess mitochondrial DNA from driving chronic immune activation. The researchers report that … Continue reading Mitophagy dampens mitochondrial DNA–triggered cGAS-STING activation in autoimmune thyroiditis
