Abstract

Graft-versus-host splenomegaly may be elicited from 500 R X-irradiated F(1) hybrid hosts if the hosts are injected with bone marrow cells and thymus cells from parental strain donors. Cells from thymus only or bone marrow only will not elicit graft-versus-host splenomegaly in these hosts. In this requirement for cells from both sources, the bone marrow cells play a nonimmunologic, proliferative role in the splenomegaly, and the thymus cells carry out the immunologic attack. Thus the mechanism of this synergism is quite different from that reported for the humoral immune response to sheep erythrocytes in which both thymus and marrow interact in the production of the specific immunologic response itself.

摘要

如果给500只经X射线照射的F(1)杂种宿主注射来自亲本品系供体的骨髓细胞和胸腺细胞,就可能引发移植物抗宿主脾肿大。仅来自胸腺的细胞或仅来自骨髓的细胞不会在这些宿主中引发移植物抗宿主脾肿大。在对来自这两种来源细胞的这种需求中,骨髓细胞在脾肿大中起非免疫性的增殖作用,而胸腺细胞则进行免疫攻击。因此,这种协同作用的机制与报道的对绵羊红细胞的体液免疫反应的机制截然不同,在后者中,胸腺和骨髓在特异性免疫反应本身的产生过程中相互作用。
