Abstract

Bone marrow cells obtained from rabbits of one allotype were injected into irradiated rabbits of a different allotype. The recipients were also injected with sheep red blood cells, and their spleen cells were tested for plaque-forming capacity 7 days later. Spleen cells of all recipients gave large numbers of plaques as did spleen cells incubated with antiserum, directed toward donor allotype. However, incubation of the recipient spleen cells with antiserum directed toward recipient allotype completely suppressed plaque formation. These results demonstrate that antibody-formation in irradiated recipients of transferred lymphoid cells is a property of the recipient animal and that the antibody-forming cell is relatively irradiation-resistant. It was also demonstrated that only viable normal bone marrow cells are capable of transferring antibody-forming capacity to irradiated recipient rabbits. Neither sonicates nor heat-killed preparations of normal rabbit bone marrow cells possessed this capacity.

摘要

从一种同种异型的兔子身上获取骨髓细胞,将其注射到不同同种异型且经过辐照的兔子体内。给受体兔子也注射绵羊红细胞,7天后检测其脾细胞的形成噬斑能力。所有受体的脾细胞都产生了大量噬斑,与用针对供体同种异型的抗血清孵育的脾细胞一样。然而,用针对受体同种异型的抗血清孵育受体脾细胞会完全抑制噬斑形成。这些结果表明,在接受转移淋巴细胞的辐照受体中抗体形成是受体动物的一种特性,并且抗体形成细胞相对抗辐照。还证明只有活的正常骨髓细胞能够将抗体形成能力转移给经辐照的受体兔子。正常兔骨髓细胞的超声裂解物和热灭活制剂均不具备这种能力。
