Analysis of the cell populations capable of initiating a response to sheep and horse erythrocyte antigens has been carried out by means of equilibrium density gradient centrifugation. The results indicate that there are at least six distinguishable AS cell populations for sheep erythrocytes, but only three for horse erythrocytes in the spleen of the Lewis rat. Evidence is presented for the existence of metabolic, physiological, and immunological differences among these populations. It is suggested that at least one population of AS cells responds only to the specific antigen and at least one other population is sensitive to stimulation by a broad range of antigens. It is assumed that the difference between these two AS cells results from a process of differentiation of AS cells primed into DNA synthesis by antigen stimulation.
通过平衡密度梯度离心法对能够启动对绵羊和马红细胞抗原反应的细胞群体进行了分析。结果表明,在Lewis大鼠的脾脏中,针对绵羊红细胞至少有六个可区分的AS细胞群体,而针对马红细胞只有三个。文中提供了这些群体之间存在代谢、生理和免疫学差异的证据。有人提出,至少有一个AS细胞群体仅对特定抗原作出反应,至少还有一个群体对多种抗原的刺激敏感。据推测,这两种AS细胞之间的差异是由抗原刺激引发进入DNA合成的AS细胞分化过程导致的。
