Peripheral Tregs survival and clonal expansionlargely depend on IL-2 and access to co-stimulatory signals such as CD28. Engagement of tumornecrosis factor receptor (TNFR) superfamily members, in particular TNFR2 and DR3, contribute topromote peripheral Tregs expansion and sustain their survival. This property can be leveraged toenhance tolerance to allogeneic transplants by tipping the balance of Tregs over conventional T cellsduring the course of immune reconstitution. This is of particular interest in peri-transplant toleranceinduction protocols in which T cell depletion is applied to reduce the frequency of alloreactive T cellsor in conditioning regimens that allow allogeneic bone marrow transplantation. These conditioningregimens are being implemented to limit long-term side effects of continuous immunosuppression andfacilitate the establishment of a state of donor-specific tolerance. Lymphopenia-induced homeostaticproliferation in response to cytoreductive conditioning is a window of opportunity to enhancepreferential expansion of Tregs during homeostatic proliferation that can be potentiated by agoniststimulation of TNFR PB MDPI SN 1422-0067 LK https://hdl.handle.net/10612/17621 UL https://hdl.handle.net/10612/17621 NO Rodriguez-Barbosa, J.-I., Schneider, P., Graca, L., Bühler, L., Perez-Simon, J.-A., & Del Rio, M.-L.
