The depressed immune response to sheep erythrocytes in young syngeneic irradiated recipients, adoptively restored with splenic cells from old donor mice, was used as an index of the changes in the immunocompentent cells with ageing. The numbers of antibody-forming cell precursors in both spleen and bone marrow appeared to be diminished with ageing. Some reduction of antigen-reactive cells was also observed in old spleens.
将年轻的同基因受照射受体对绵羊红细胞的免疫反应抑制,通过来自老年供体小鼠的脾细胞进行过继性恢复,以此作为免疫活性细胞随年龄变化的指标。脾和骨髓中抗体形成细胞前体的数量似乎随年龄增长而减少。在老年脾脏中也观察到抗原反应性细胞有所减少。
