Fc fragments derived from human and murine Ig were found to be potent adjuvants when administered with antigen. Both the in vivo and in vitro anti- sheep erythrocytes (SRBC) responses were significantly enhanced by Fc fragments. The adjuvant effect was shown to be extremely dependent upon the dose of antigen used, with the greatest enhancement occurring when suboptimal doses of antigen are employed. The anti-genicity of the Fc molecule was not related to its adjuvanticity because homologous Fc was as potent an adjuvant as heterologous Fc. Moreover, human Fc fragments enhanced anti-SRBC responses in mice which were tolerant to human gamma globulin.
当与抗原一起给药时,发现源自人源和鼠源Ig的Fc片段是有效的佐剂。Fc片段显著增强了体内和体外抗绵羊红细胞(SRBC)反应。佐剂效应显示出极大地依赖于所用抗原的剂量,当使用次优剂量的抗原时增强作用最大。Fc分子的抗原性与其佐剂性无关,因为同源Fc与异源Fc一样是有效的佐剂。此外,人Fc片段增强了对人γ球蛋白耐受的小鼠的抗SRBC反应。
