Cellular senescence as a therapeutic target for aging intervention.

Area of Science:

• Gerontology and cellular biology
• Molecular mechanisms of aging
• Pathology and therapeutic interventions

Background:

• Cellular senescence is a stress-induced state linked to aging and disease.
• Accumulated senescent cells (SnCs) impair tissue function and promote inflammation.
• SnCs are key drivers of age-related decline and potential therapeutic targets.

Purpose of the Study:

• To review current strategies for targeting cellular senescence.
• To highlight the role of SnCs in aging pathologies.
• To discuss future directions in senescence-targeted therapies.

Main Methods:

• Review of existing literature on cellular senescence and aging.
• Analysis of various senescence-targeting strategies (senolytics, senomorphics, immunotherapy, restoration).
• Discussion of challenges and future prospects in the field.

Main Results:

• Multiple therapeutic strategies targeting senescent cells are under development.
• These strategies aim to eliminate SnCs, modulate their secretory phenotype, or restore cellular function.
• Precise stratification of senescent states and safety assessments are crucial for efficacy.

Conclusions:

• Senescence-targeted interventions hold promise for mitigating age-associated diseases.
• Advancements require better understanding of senescent cell heterogeneity and optimized delivery systems.
• Future research should focus on safety, efficacy, and personalized therapeutic approaches.
