Mitochondrial medicine is a multidisciplinary academic field dedicated to investigating the fundamental roles of mitochondria in cellular physiology, energy metabolism, quality control, signaling, and their intricate involvement in the pathogenesis of human diseases. This research encompasses the study of mitochondrial genetics (mtDNA and nDNA), biochemical pathways like oxidative phosphorylation, and the development of diagnostic and therapeutic approaches targeting mitochondrial dysfunction to restore health.
