“…Consequently, senolytic and senomorphic strategies have gained great scientific interest in recent years. The first approach consists of selectively eliminating senescent cells, while the second targets senescence-inducing pathways and factors involved in SASP to prevent paracrine senescence and reduce the deleterious effects of inflammation and oxidative stress on tissues (Zhu et al, 2015;Zhang et al, 2022;Zhu and Lerman, 2022).…”
