Journal Club: Slaying the Sleeper Cells of Aging with CAR T

CAR T therapy is a groundbreaking medicine that uses engineered T cells to attack cancer. But CAR T cells (that is, chimeric antigen receptor T cells) can be programmed to recognize a huge range of target proteins and cell types. So what other types of cells should we train CAR Ts to recognize and destroy to improve human health?On this episode of the a16z Journal Club, a16z General Partner Jorge Conde, bio deal team partner Andy Tran, and Lauren Richardson discuss new research published in Nature in which the authors engineer CAR T cells to recognize and kill senescent cells. Cellular senescence is a process where cells stop dividing (sort of go to sleep), and in many cases this can be protective, like its role in tumor suppression, but if too many cells become senescent of if they are not removed, they can trigger inflammation and cause disease, like in atherosclerosis and type 2 diabetes. Critically, senescent cells build up as we age and contribute to a whole host of age-related conditions. In this episode we cover how the authors created these senescence killing (aka senolytic) CAR T cells, the diseases that could be treated with senolytic CAR Ts, the hurdles to getting them into the clinic, and how they could potentially be used to treat aging and possibly improve longevity.“Senolytic CAR T cells reverse senescence-associated pathologies” in Nature (June 2020) by Corina Amor, Judith Feucht, Josef Leibold, Yu-Jui Ho, Changyu Zhu, Direna Alonso-Curbelo, Jorge Mansilla-Soto, Jacob A.
