Serums, diets, yoga; all things that older generations attempt to look as young as possible. People will do anything to have their skin wrinkle-free, their body in shape, and their mind updated on trends. Mostly, we strive for the physical appearance of being young, yet there’s so much more to getting old than simply old lady looks. As we get older, we become more susceptible to diseases. Scientists are finding ways to strengthen cells in the immune system to fight off age-related diseases by an ingredient in a common beverage; red wine.
The anti-aging protein, SIRT1, is commonly used to fight off and prevent age-related diseases. It is now revealed that it can be used to rejuvenate cells in the immune system. We all have T cells that protect our immune system from corrupted cells such as cancer or viruses. As we age, T cells do too and start to lose important proteins called SIRT1 and CD28. “We studied human T cells, isolated from blood donors of all ages, to compare mature cytotoxic T cells with naive ones,” said Philip Ansumana Hull, a graduate student in Ott’s lab and one of the first authors of the study. (cite) T cells were found to have a high concentration of SIRT1. This limits their toxic effects and contributes to the prevention of the cells from entering glycolysis to use sugar as an energy source. 
Based on a better understanding of the crucial role played by SIRT1 in the aging of T cells, the researchers identified two potential new drug targets. First, new drugs could be developed to strengthen SIRT1 to rejuvenate mature cytotoxic T cells or keep them from progressing too quickly into a highly toxic state. “This could postpone the development of age-related diseases,” said Mark Y. Jeng, the study’s other first author and former graduate student in Ott’s lab. “It could also help people with a weaker immune system fight infections or better respond to immune vaccination, such as seniors or chronically-infected patients.” (cite)
