Cellular Senescence Reduction Strategies are a collection of therapeutic and lifestyle interventions aimed at decreasing the burden of senescent cells, often termed “zombie cells,” within tissues. Senescent cells cease dividing but remain metabolically active, secreting a pro-inflammatory senescence-associated secretory phenotype (SASP) that drives tissue dysfunction and aging. Reducing this cellular load is a core focus of longevity and regenerative medicine. These strategies are vital for mitigating chronic inflammation and preserving tissue function.
Origin
This field originates from gerontology and molecular biology research that identified cellular senescence as a fundamental mechanism of biological aging and chronic disease pathogenesis. The clinical translation involves developing senolytic agents—compounds that selectively induce apoptosis in senescent cells—and senomorphic agents that suppress the harmful SASP. This represents a targeted approach to manipulating the aging process at a cellular level.
Mechanism
These strategies function by either selectively eliminating senescent cells through senolytic compounds or by modulating the intracellular signaling pathways that maintain the senescent state and regulate SASP production. Key targets include anti-apoptotic pathways specific to senescent cells and transcription factors that govern the inflammatory secretome. By clearing these dysfunctional cells, the tissue microenvironment health is restored, which improves organ function and systemic resilience.
