Special Issue The Role of Cellular Senescence in Health Biology Diagrams An increasing number of researchers are exploring whether learning to harness a cellular state known as senescence — during which damaged cells resist removal by apoptosis, linger, and harm neighboring normal cells — might hold the key to revitalizing aging tissues and increasing healthy, active years of life. Senescence can in turn drive the consequential aging hallmarks in response to damage: stem cell exhaustion and chronic inflammation. Other responses to damage, such as proteostatic dysfunction and nutrient signaling disruption, are also integrally linked with the senescence response.

Special Issue The Role of Cellular Senescence in Health Biology Diagrams

Abstract. Background: Cellular senescence is a state of irreversible cell cycle arrest that serves as a critical regulator of tissue homeostasis, aging, and disease.While transient senescence contributes to development, wound healing, and tumor suppression, chronic senescence drives inflammation, tissue dysfunction, and age-related pathologies, including cataracts. Senescence, from the Latin word senex, means "growing old," is an irreversible growth arrest which occurs in response to damaging stimuli, such as DNA damage, telomere shortening, telomere dysfunction and oncogenic stress leading to suppression of potentially dysfunctional, transformed, or aged cells. Cellular senescence is characterized by

Cellular senescence is a stable and terminal state of growth arrest in which cells are unable to proliferate despite optimal growth conditions and mitogenic stimuli (Boxes 1,2; Fig. 1).Senescent While cell senescence can play protective roles (e.g., Over the past decade, the significance of cellular senescence in brain aging has grown substantially. Studies using transgenic mouse models (e.g., INK-ATTAC, p16-3MR) and senolytic agents (e.g., D + Q, navitoclax) have demonstrated that targeting senescent cells can mitigate numerous

Senescence was initially described for replicative cells and is still mainly linked to replication-competent cell moieties, whereas there is currently no clear association between the aging process and the turnover rate of cells in different tissues and organs [46,47], a fact that seemingly underlines the independence of the two processes.

Does cellular senescence hold secrets for healthier aging? Biology Diagrams

Aging is the major risk factor for cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. Although we are far from understanding the biological basis of aging, research suggests that targeting the aging process itself could ameliorate many age-related pathologies. Senescence is a …
