Abstract : Tregs play a critical role in the control of immune responses and tolerance induction; however our understanding of CD8+ Tregs is limited while they are particularly promising for therapeutic application. We previously reported that CD8+CD45RC[low] Tregs use IFNγ and IL-34 to suppress donor responses in a rat model of allotransplantation (Guillonneau et al, JCI, 2007 ; Bezieetal, JCI, 2015). Here, we aim to characterize human CD8+ Tregs to assess their potential for cell therapy in transplantation in comparison to CD4+CD25[high]CD127- Tregs .
