Aging is a multifactorial process that affects the organisms at genetic, molecular and cellular levels. This process modifies several tissues with a negative impact on cells physiology, tissues and organs functionality, altering their regeneration capacity. The chronic low-grade inflammation typical of aging, defined as inflammaging, is a common biological factor responsible for the decline and beginning of the disease in age. A murine parabiosis model that combines the vascular system of old and young animals, suggests that soluble factors released by young individuals may improve the regenerative potential of old tissue. Therefore, circulating factors have a key role in the induction of aging phenotype. Moreover, lifestyle can influence the physiological status of multiple organs, via epigenetic mechanisms. Recently, microRNAs are considered potential sensors of aging.

Abstract

Aging is a multifactorial process that affects the organisms at genetic, molecular and cellular levels. This process modifies several tissues with a negative impact on cells physiology, tissues and organs functionality, altering their regeneration capacity. The chronic low-grade inflammation typical of aging, defined as inflammaging, is a common biological factor responsible for the decline and beginning of the disease in age. A murine parabiosis model that combines the vascular system of old and young animals, suggests that soluble factors released by young individuals may improve the regenerative potential of old tissue. Therefore, circulating factors have a key role in the induction of aging phenotype. Moreover, lifestyle can influence the physiological status of multiple organs, via epigenetic mechanisms. Recently, microRNAs are considered potential sensors of aging.
