WebApr 20, 2024 · Induction of allograft tolerance has been considered the ultimate goal in organ transplantation. Although numerous protocols to induce allograft tolerance have been reported in mice, a chimerism‐based approach through donor haematopoietic stem cell transplantation has been the only approach to date that induced allograft tolerance … Webchimerism induction protocols. Although chimerism takes advantage of central tolerance (7–9), with costimulatory-based induction protocols, more of the recipient cel-lular compartment is left intact and must be subject to peripheral tolerance mechanisms (11,12,46). Dermal APCs are resistant to radiation (48); therefore, NOD APCs
WebTo induce chimerism, a conditioning regimen is required to suppress the recipient’s immune system and enable donor bone marrow engraftment in the space physically vacated by recipient cell death. 21 Such regimens usually consist of irradiation, … WebNov 4, 2024 · The mixed chimerism approach is an exceptionally potent strategy for the induction of donor-specific tolerance in organ transplantation and so far the only one that was demonstrated to work in the clinical setting. Regulatory T cells (Tregs) have been shown to improve chimerism induction in experimental animal models.
WebA promising approach is the induction of mixed hematopoietic chimerism, which can be achieved in experimental models with far less toxic induction therapy.
