Senescent cells accumulate with age and contribute to the normal aging process as well as age-related disorders. Research in animal models has shown thatin vivoadministration of compounds calledsenolytics, which selectively eliminate senescent cells, can reduce inflammation, enhance immune system function,...
Another critical factor is cellular senescence, where cells lose their ability to function effectively. These senescent cells accumulate over time, contributing to the deterioration of tissues and organs. Researchers are exploring ways to remove or rejuvenate these cells to extend life. Additionall...
They are alive but can no longer divide to create new cells. Senescent cells send signals to neighbouring cells triggering them to age more quickly which can lead to inflammation. The good news is that potent plant molecules have been shown to kick start a process c...
Although a beneficial cell-autonomous role of senescence is to facilitate the clearance of senescent cells by the immune system involving inflammatory cells such as macrophages, phagocytes and natural killer (NK) cells, active products of these cells are biologically deleterious and can drive various ...
Altered expression of chemokines and cytokines via actual production as well as receptor expression are found in both human T cells and murine models of aging. Immunosenescence and clonal energy is also a significant contributor to reduction T cell activity in aging individuals. These senescent T cel...
Skin is a complex organ consisting of two very different tissue compartments, the epidermis and the dermis, which comprise cells of diverse origin and function. Establishing and maintaining the functionality of skin requires not only tightly regulated pr
The scales used for alopecia, such as the SALT (severity of alopecia tool) score, are not highly applicable to the situation of senescent thinning. Establishing a “norm” volume of hair for a patient would be important, as the differences of hair shafts prevents comparisons between patients. ...
cellular senescence is completely unknown. Just which p53-regulated genes initiate this state remain unclear. Indeed, there are very few reliable biomarkers for the senescent state and we do not know what mediates this process of irreversible division leaving the cell in a metabolically active state...

(Loseva et al.2014). Since senescence is linked to many age-related pathologies, including cardiovascular disease, the increase of senescent cells with a tissue following chronic radiation exposure would be expected to cause premature ageing. However, there is contradictory evidence. First, some ...
