Klotho Protein: A Multifaceted Guardian of Healthy Aging and Its Therapeutic Potential

The Klotho protein, encoded by the KL gene, has garnered significant attention as a pivotal biomolecule in the field of aging research. Its expression levels are closely correlated with both lifespan and overall health status, exerting influence over critical physiological processes such as metabolic homeostasis, oxidative stress response, and inflammation modulation. This review aims to systematically examine the multifaceted roles of Klotho within the context of aging and its implications for various age-associated disorders. We highlight the emerging evidence suggesting that Klotho may serve as a key regulator in age-related pathologies, including cardiovascular diseases, neurodegenerative disorders, and metabolic syndromes. Furthermore, we explore the potential of Klotho as a therapeutic target, positing that interventions aimed at enhancing Klotho activity could offer novel strategies for alleviating the health burdens experienced by the aging population.
