Research advances in understanding the senescence-associated secretory phenotype and relevant drugs / 药学学报

ABSTRACT

The senescence-associated secretory phenotype (SASP) is a generic term for the secretion of a series of cytokines such as pro-inflammatory factors, chemokines and proteases, and is a key feature of senescent cells. SASP is a double-edged sword that can resist a harmful environment in normal cells, but with the decline of body function, the massive secretion of cytokines, chemokines and proteases accelerates aging while inducing inflammation, leading to the development of various aging-related diseases. This article reviews the composition and physiological functions of SASP, the changes in SASP during aging, the regulatory pathways associated with SASP, and the anti-aging drugs that regulate SASP. This article aims to present a more comprehensive understanding of SASP and lay the foundation for SASP-based anti-aging research and the discovery of new targets for anti-SASP drugs.
