The quest for extended human healthspan and lifespan has driven scientific inquiry for centuries. In recent decades, advancements in molecular biology and genetics have propelled gene therapy to the forefront of anti-aging research. This field explores the potential to modify gene expression or introduce new genetic material into cells to combat the molecular and cellular hallmarks of aging. Understanding these intricate mechanisms is crucial for developing effective interventions that could redefine the human experience of aging. Cellular longevity, often synonymous with healthy aging, involves maintaining cellular function, integrity, and regenerative capacity over time. Gene therapy offers a powerful toolkit to target specific genes associated with age-related decline, from DNA repair pathways to metabolic regulation. This comprehensive exploration delves into the scientific underpinnings, current breakthroughs, and future prospects of gene therapy as a transformative approach to...
