CD27low Natural Killer Cells Prolong Allograft Survival in Mice by Controlling Alloreactive CD8+ T Cells in a T-Bet–Dependent Manner

BackgroundNatural killer (NK) cells play a dichotomous role in alloimmune responses because they are known to promote both allograft survival and rejection. The aim of this study was to investigate the role of functionally distinct NK cell subsets in alloimmunity with the hypothesis that this dichot
