Hearts from alpha1,3-galactosyltransferase knockout pigs (GalT-KO, n = 8) were transplanted heterotopically into baboons using an anti-CD154 monoclonal antibody-based regimen. The elimination of the galactose-alpha1,3-galactose epitope prevented hyperacute rejection and extended survival of pig hearts in baboons for 2-6 months (median, 78 d); the predominant lesion associated with graft failure was a thrombotic microangiopathy, with resulting ischemic injury. There were no infectious complications directly related to the immunosuppressive regimen. The transplantation of hearts from GalT-KO pigs increased graft survival over previous studies.
将8只α1,3-半乳糖基转移酶基因敲除猪(GalT-KO)的心脏,采用基于抗CD154单克隆抗体的方案异位移植到狒狒体内。半乳糖-α1,3-半乳糖表位的消除预防了超急性排斥反应,并使猪心脏在狒狒体内的存活期延长了2至6个月(中位数为78天);与移植物衰竭相关的主要病变是血栓性微血管病,并导致缺血性损伤。没有与免疫抑制方案直接相关的感染并发症。与先前的研究相比,GalT-KO猪心脏的移植提高了移植物的存活率。
