Interaction of microgram quantities of highly purified rabbit anti-TNP antibodies with TNP-substituted HeLa, HEp-2, and L cells caused an intense stimulation of radioactive nucleoside ([(125)I]UdR and [(3)H]TdR) uptake which was maximal 24-72 h after exposure of cells to antibody. The stimulation of nucleoside uptake and presumaly DNA synthesis was shown to be immuno logically mediated because unsubstituted cells were not stimulated by anti-TNP antibody, normal rabbit gamma globulin did not stimulate TNP-cells, and a hapten inhibitor, epsilon-DNP-lysine, prevented the stimulation of TNP-cells by anti-TNP antibody. These findings demonstrate that interaction of antibody with cell surface antigen can alter cell membrane transport, and possibly can enhance cell growth.
微克量的高度纯化兔抗三硝基苯(TNP)抗体与TNP取代的HeLa细胞、HEp - 2细胞和L细胞相互作用,可强烈刺激放射性核苷([¹²⁵I]尿苷(UdR)和[³H]胸腺嘧啶核苷(TdR))摄取,细胞接触抗体后24 - 72小时摄取量达到最大值。核苷摄取的刺激以及推测的DNA合成被证明是由免疫介导的,因为未被取代的细胞不会被抗TNP抗体刺激,正常兔γ球蛋白不会刺激TNP细胞,并且一种半抗原抑制剂ε - DNP - 赖氨酸可阻止抗TNP抗体对TNP细胞的刺激。这些发现表明抗体与细胞表面抗原的相互作用可改变细胞膜转运,并且可能增强细胞生长。
