Senescent cells accumulate throughout the body with age. They are constantly created and destroyed throughout life, but the balance between creation and destruction is upset with age, leading to an accumulated burden of cellular senescence. These cells secrete a potent mix of signals that produce chronic inflammation, disrupt tissue structure and cell function, and encourage other cells to also become senescent. The more senescent cells, …
