Abstract

Background: Higher numbers of senescent cells have been implicated in age-related disease pathologies. However, whether different diseases have different senescent phenotypes is unknown. Here we provide a systematic overview of the current available evidence of senescent cells in age-related diseases pathologies in humans and the markers currently used to detect senescence levels in humans.

Methods: PubMed, Web of Science and EMBASE were systematically searched from inception to the 29th of September 2019, using keywords related to 'senescence', 'age-related diseases' and 'biopsies'.

Results: In total 12,590 articles were retrieved of which 103 articles were included in this review. The role of senescence in age-related disease has been assessed in 9 different human organ system and 27 different age-related diseases of which heart (27/103) and the respiratory systems (18/103) are the most investigated. Overall, 27 different markers of senescence have been used to determine cellular senescence and the cell cycle regulator p16ink4a is most often used (23/27 age-related pathologies).

Conclusion: This review demonstrates that a higher expression of senescence markers are observed within disease pathologies. However, not all markers to detect senescence have been assessed in all tissue types.

Keywords: Age-related disease; Ageing; Cellular senescence; Humans; Pathology.
