Decay-accelerating factor (DAF) has been reported to be a cellular receptor for several enteroviruses. Buffalo green monkey kidney (BGMK) cells expressing human DAF (BGMK-hDAF cells) showed increased susceptibility and sensitivity to several types of enteroviruses compared to wild-type BGMK cells. When 17 frozen positive clinical samples were tested, BGMK cells detected 8 and BGMK-hDAF cells detected 16. Since the CaCo-2 cell line has been documented to support the replication of most enteroviruses, CaCo-2 cells were mixed with BGMK-hDAF cells in order to increase the number of viruses detected. Thirty-four frozen clinical samples that previously had tested positive for enteroviruses were tested, and the following numbers were detected: 33 of 34 by CaCo-2/BGMK-hDAF cells, 29 of 34 by CaCo-2/BGMK cells, 28 of 34 by H292/RD (E-mix A) and A-549/BGMK (E-mix B) cells, and 26 of 34 by MRC-5 and pRhMK cells.
衰变加速因子(DAF)据报道是几种肠道病毒的细胞受体。与野生型水牛绿猴肾(BGMK)细胞相比,表达人DAF的BGMK细胞(BGMK-hDAF细胞)对几种类型的肠道病毒表现出更高的易感性和敏感性。当检测17份冷冻的阳性临床样本时,BGMK细胞检测出8份,BGMK-hDAF细胞检测出16份。由于已证明CaCo-2细胞系能支持大多数肠道病毒的复制,因此将CaCo-2细胞与BGMK-hDAF细胞混合以增加检测到的病毒数量。对之前检测出肠道病毒呈阳性的34份冷冻临床样本进行了检测,检测到的数量如下:CaCo-2/BGMK-hDAF细胞检测出34份中的33份,CaCo-2/BGMK细胞检测出34份中的29份,H292/RD(E-mix A)和A-549/BGMK(E-mix B)细胞检测出34份中的28份,MRC-5和pRhMK细胞检测出34份中的26份。
