"Senolytic CAR T Cells: Unlocking the Fountain of Youth for Age-Related Metabolic Dysfunction"

Researchers have developed senolytic CAR T cells targeting the cell-surface protein uPAR, which is upregulated on senescent cells in aged tissues. These CAR T cells were found to effectively eliminate senescent cells in aged mice, leading to a reduction in pro-inflammatory cytokines and improved metabolic function. The treatment was well tolerated and resulted in improved glucose tolerance and exercise capacity in the aged mice. The study suggests that senolytic CAR T cells have the potential to address age-related metabolic dysfunction and improve healthspan.
