Mitochondrial DNA (mtDNA)
othermtDNA released from injured cells activates pattern-recognition receptors to trigger innate immune activation and plaque inflammation in atherosclerosis.
Pathway placement
Cascade stepPlaque inflammation
Confidencemedium
RationaleReleased from damaged cells; acts as a DAMP (danger-associated molecular pattern) to trigger innate inflammation and atherosclerosis progression.
Also acts inMyocardial injury
Druggability
Not assessed (no mapped human gene target).
