Abstract
Frailty is the main geriatric syndrome, which is closely associated with age-related diseases and aging in general. Being considered the main pathogenetic mechanism of aging, low-grade chronic inflammation potentially contributes to increased degradation of the essential amino acid tryptophan through the kynurenine pathway. Active metabolites of the kynurenine pathway, when accumulated, implement their immunomodulatory, pro-inflammatory and cytotoxic properties, thereby supporting and enhancing the aging process. Over the past decade, data have been collected on the role of an unbalanced kynurenine pathway in the pathogenesis of frailty and age-related diseases. This review summarizes clinical and experimental data on the importance of kynurenine pathway analysis as a valuable tool for risk stratification and prognosis of frailty and age-related diseases.
期刊介绍：
Advances in Gerontology focuses on biomedical aspects of aging. The journal also publishes original articles and reviews on progress in the following research areas: demography of aging; molecular and physiological mechanisms of aging, clinical gerontology and geriatrics, prevention of premature aging, medicosocial aspects of gerontology, and behavior and psychology of the elderly.
