Reversal of this process may be therapeutically beneficial.
WebMechanical stress is one of the factors that induces senescence in cells which stop dividing and acquire the senescence-associated secretory phenotype (SASP). In its turn, these cells affect nearby cells through paracrine signaling molecules, such as cytokines and chemokines [ 22 , 23 ]. WebSep 16, 2024 · Senescence is a cellular stress response triggered by diverse stressors, including oncogene activation, where it serves as a bona-fide tumour suppressor mechanism. Senescence can be transmitted to neighbouring cells, known as paracrine secondary senescence. Secondary senescence was initially described as a paracrine …
