Mitochondrial Health: Cellular Energy, Aging, and Longevity

https://www.news-medical.net/health/Mitochondrial-Health-Cellular-Energy-Aging-and-Longevity.aspx Mitochondria sustain cellular energy production while coordinating metabolism, redox signaling, quality control, and stress responses that influence aging and healthspan. Age-related disruption of mitochondrial DNA, dynamics, mitophagy, and nutrient sensing contributes to disease, while emerging interventions remain promising but largely unproven for extending human lifespan. This article explores how mitochondrial health influences energy production, aging, and longevity, as well as emerging strategies being investigated to preserve mitochondrial function and support healthy aging. Longevity refers to lifespan, whereas healthspan describes the period of life spent with preserved function and without major age-related disease.3,5 Mitochondria are also dynamic signaling and quality-control hubs whose networks continually undergo fission, fusion, transport, and selective removal.1,3,5 Age-related mitochondrial changes may be drivers, consequences or initially compensatory responses to cellular stress, with their effects varying by tissue, timing and metabolic context.
