Targeting Senescent Cells: Possible Implications for Delaying Skin Aging: A Mini-Review

Area of Science:

• Gerontology
• Dermatology
• Cell Biology

Background:

• Cellular senescence is a stress response that accumulates with age in various tissues, including the skin.
• Senescent cells exhibit a senescence-associated secretory phenotype (SASP), releasing inflammatory factors that contribute to tissue dysfunction.
• The accumulation of senescent cells and their SASP are implicated in the aging process and age-related diseases.

Purpose of the Study:

• To review the role of senescent cells in skin aging.
• To examine age-related mechanisms and phenotypes associated with cellular senescence in the skin.
• To discuss therapeutic strategies targeting senescent cells for aging and age-related skin conditions.

Main Methods:

• Literature review of studies on cellular senescence in skin aging.
• Analysis of age-related mechanisms and phenotypes of senescent cells.
• Discussion of signaling pathways involved in senescent cell survival and secretion.

Main Results:

• Senescent cells accumulate in aging skin and contribute to its functional decline via SASP.
• Aberrant behavior of senescent cells is a key feature of skin aging.
• Specific signaling pathways in senescent cells present therapeutic targets.

Conclusions:

• Targeting senescent cells and their SASP is a viable therapeutic strategy to combat skin aging.
• Understanding senescent cell signaling pathways is crucial for developing anti-aging therapies.
• Selective targeting of senescent cells may delay aging and age-related diseases.
