Cellular senescence in age-related disorders

Area of Science:

• Geroscience
• Cellular and Molecular Biology
• Aging Research

Background:

• Aging is associated with a significant burden of chronic diseases.
• Cellular senescence, a state of irreversible cell cycle arrest, is a hallmark of aging.
• Senescent cells and their secreted factors contribute to age-related tissue dysfunction and disease.

Purpose of the Study:

• To explore the role of cellular senescence in age-associated chronic diseases.
• To evaluate the therapeutic potential of targeting senescent cells for healthspan extension.

Main Methods:

• Review of geroscience discoveries and studies in model organisms.
• Analysis of the impact of senescent cells on various age-related conditions.
• Examination of senotherapeutic strategies, including senolytics and senomorphics.

Main Results:

• Cellular senescence is implicated in numerous age-related diseases, including osteoporosis, cardiovascular disease, and neurodegeneration.
• Therapeutic elimination or modulation of senescent cells in mice can prevent or alleviate these conditions.
• Senotherapeutic approaches demonstrate potential for compressing morbidity.

Conclusions:

• Targeting cellular senescence is a viable strategy to combat age-associated chronic diseases.
• Senolytics and senomorphics offer promising avenues for extending human healthspan and reducing disease burden.
