Abstract

The cytokinetics of the antibody to Type III pneumococcal polysaccharide (SSS-III) were characterized by an immuno-plaque procedure using erythrocytes sensitized with SSS-III. Prior immunization, irrespective of the doses employed, did not result in the development of immunological memory; instead, low-dose paralysis was produced in mice previously immunized with all doses of SSS-III. Dose-response studies revealed that within a given dose range, there was a direct relationship between the immunizing dose and the magnitude of the antibody response obtained. The dose-response curve for SSS-III showed a single optimal dose for immunization; doses only slightly in excess of the optimal dose produced a significant reduction in the magnitude of the antibody response. The implications of these findings, with respect to the development of paralysis to SSS-III, are discussed.

摘要

采用经III型肺炎球菌多糖(SSS-III)致敏的红细胞,通过免疫斑程序对III型肺炎球菌多糖抗体(SSS-III)的细胞动力学进行了表征。预先免疫,无论使用何种剂量,均未导致免疫记忆的形成;相反,先前用所有剂量的SSS-III免疫的小鼠产生了低剂量麻痹。剂量反应研究表明,在给定剂量范围内,免疫剂量与获得的抗体反应强度之间存在直接关系。SSS-III的剂量反应曲线显示出单一的最佳免疫剂量;仅略高于最佳剂量的剂量会导致抗体反应强度显著降低。讨论了这些发现对于SSS-III麻痹发生的意义。
