Severe acute respiratory syndrome coronavirus 2 did not replicate efficiently in 13 bat cell lines, whereas severe acute respiratory syndrome coronavirus replicated efficiently in kidney cells of its ancestral host, the Rhinolophus sinicus bat, suggesting different evolutionary origins. Structural modeling showed that RBD/RsACE2 binding may contribute to the differential cellular tropism.
严重急性呼吸综合征冠状病毒 2 在 13 种蝙蝠细胞系中不能有效复制,而严重急性呼吸综合征冠状病毒在其祖先宿主马蹄蝠的肾脏细胞中有效复制,这表明它们具有不同的进化起源。结构建模表明,RBD/RsACE2 结合可能有助于不同的细胞趋向性。
