Cellular Senescence in Cardiovascular and Metabolic Diseases

Posted by in categories: biotech/medical, life extension

Today, we wanted to bring your attention to a new open access paper. The authors here review the role of cellular senescence in the context of the cardiovascular and metabolic diseases of aging. This paper puts special focus on the aging of the vascular system and the role that accumulating numbers of senescent cells play in that process.

What is cellular senescence?

As the body ages, increasing amounts of cells enter a state of senescence. Senescent cells do not divide or support the tissues of which they are a part; instead, they emit a range of potentially harmful signals known collectively as the senescence-associated secretory phenotype (SASP). Senescent cells normally destroy themselves via a programmed process called apoptosis, and they are removed by the immune system; however, as the immune system weakens with age, increasing numbers of these senescent cells escape this process and build up.
