This study proves the tolerogenicity of polymorphic allopeptides. Combined administration of peptides derived from the alpha 1 (intrathymal) and the alpha 2 (intraperitoneal) helical region of the donor RT1.A(a) molecule induced specific tolerance in a rat model of cardiac allotransplantation. The underlying tolerance mechanism was mediated by selective depletion of alloreactive T cells within the thymus and Fas-L-induced apoptosis within the graft.
本研究证实了多态性异源肽的耐受性。联合给予源自供体RT1.A(a)分子α1(胸腺内)和α2(腹腔内)螺旋区域的肽,可在心脏同种异体移植大鼠模型中诱导特异性耐受。潜在的耐受机制是由胸腺内同种反应性T细胞的选择性耗竭以及移植物内Fas-L诱导的细胞凋亡介导的。
