Transplantation tolerance across histoincompatibilities in multiple non-H-2 minors (B10.BR into CBA/Ca) and "minor" plus H-2D (B10.A into CBA/Ca) antigens has been achieved successfully by combined adult bone marrow transplantation and treatment with CD4 and CD8 mAbs. The tolerant state was confirmed by permanent acceptance of donor strain skin grafts, and in vitro unresponsiveness to donor cells. Tolerance was associated with partial donor chimerism to various degrees. Tolerance to minor transplantation antigens induced in this manner was restricted to recipient-type MHC. The possibility was raised that tolerance resulted, at least in part, from clonal anergy rather than deletion.
通过成年骨髓移植联合CD4和CD8单克隆抗体治疗,已成功实现了在多个非H-2次要抗原(将B10.BR小鼠的骨髓移植到CBA/Ca小鼠)以及“次要”抗原加H-2D抗原(将B10.A小鼠的骨髓移植到CBA/Ca小鼠)不相容情况下的移植耐受。通过永久接受供体品系皮肤移植以及体外对供体细胞无反应性,证实了耐受状态。耐受与不同程度的部分供体嵌合体有关。以这种方式诱导的对次要移植抗原的耐受仅限于受体型MHC。这就提出了一种可能性,即耐受至少部分是由克隆无能而非克隆缺失导致的。
