An Anti-Aging Protein Could Be Targeted to Rejuvenate Immune Cells

Melanie Ott

Aging proteins have long been shown to protect against age-related diseases, such as cancer, neurodegeneration, and cardiovascular disease. A study by researchers at the Gladstone Institutes now reveals that one such protein could also be targeted to rejuvenate cells in the immune system.

The protein in question is called SIRT1, more commonly known for being activated by red wine. In the new study, published in the Journal of Experimental Medicine, the scientists found that it is also involved in how cells in the immune system develop with age.

They wanted to find out how this anti-aging protein affects a specific category of immune cells known as cytotoxic T cells. These cells are highly specialized guardians of the immune system and their role is to kill cells infected by a virus, damaged cells, or cancer cells.
