使用兔抗人 HRF 通过免疫吸附从正常人红细胞 (E) 中分离出 65 kD 同源限制因子 (HRF)。该蛋白质被放射性标记并掺入绵羊红细胞(Es)的膜中。携带 HRF 的 Es 对 C5b-9 反应性裂解的敏感性显着降低。每个细胞含有 1,000-3,000 个 HRF 分子并用兔 IgG 抗 Es 致敏的 Es-HRF 也比用 IgG 抗体致敏的未经处理的 Es 更不易被人大颗粒淋巴细胞 (LGL) 裂解。类似地,患有阵发性睡眠性血红蛋白尿症(PNH)、缺乏 HRF 并用 IgG 抗体致敏的患者的人 E 也经历了人 LGL 的裂解。通过掺入分离的人 HRF 消除裂解。将人衰变加速因子 (DAF) 掺入致敏 Es 对抗体依赖性细胞介导的细胞毒性没有影响。此外,细胞结合的人 HRF 可以抑制人细胞毒性淋巴细胞的分离的溶细胞 C9 相关蛋白 (C9RP) 对 Es 的裂解。这些结果表明,HRF 不仅抑制 C5b-9 的通道形成,还抑制细胞毒性淋巴细胞的通道形成。
The 65 kD homologous restriction factor (HRF) was isolated from normal human erythrocytes (E) by immunoadsorption using rabbit anti-human HRF. The protein was radiolabeled and incorporated into the membrane of sheep erythrocytes (Es). Es bearing HRF exhibited a markedly reduced susceptibility to reactive lysis by C5b-9. Es-HRF with 1,000-3,000 HRF molecules per cell and sensitized with rabbit IgG anti-Es also were less susceptible to lysis by human large granular lymphocytes (LGL) than untreated Es sensitized with IgG antibody. Similarly, human E of a patient with paroxysmal nocturnal hemoglobinuria (PNH), lacking HRF and sensitized with IgG antibody underwent lysis by human LGL. Lysis was abrogated by incorporation of isolated human HRF. Incorporation of human decay-accelerating factor (DAF) into sensitized Es had no effect on antibody-dependent, cell-mediated cytotoxicity. Furthermore, lysis of Es by the isolated cytolytic C9-related protein (C9RP) of human cytotoxic lymphocytes could be inhibited by cell bound human HRF. These results suggest that HRF inhibits channel formation not only by C5b-9, but also by cytotoxic lymphocytes.
