猴动脉炎病毒在一些非洲灵长类物种中是地方性的,当它们进入新的灵长类宿主物种时会引起致命的出血热。我们发现CD 163作为猴出血热病毒(SHFV;一种猴动脉炎病毒)的细胞内受体,这是一种罕见的病毒进入模式,与其他引起出血热的病毒(例如,埃博拉病毒和拉沙病毒)。此外,SHFV进入人单核细胞并在其中复制,表明病毒复制所需的所有人细胞蛋白的全部功能。因此,自然界中的猿动脉炎病毒可能不需要对人类宿主进行重大适应。考虑到至少有三种猴动脉炎病毒在宿主转换后引起圈养猕猴的致命感染,以及人类对这一病毒家族的免疫学幼稚,开发用于人类监测的血清学检测应该是优先事项。
Simian arteriviruses are endemic in some African primate species and can cause fatal hemorrhagic fevers when they cross into new primate host species. We find that CD163 acts as an intracellular receptor for simian hemorrhagic fever virus (SHFV; a simian arterivirus), a rare mode of virus entry that is shared with other hemorrhagic fever-causing viruses (e.g., Ebola and Lassa viruses). Further, SHFV enters and replicates in human monocytes, indicating full functionality of all of the human cellular proteins required for viral replication. Thus, simian arteriviruses in nature may not require major adaptations to the human host. Given that at least three simian arteriviruses have caused fatal infections in captive macaques after host-switching, and that humans are immunologically naïve to this family of viruses, development of serology tests for human surveillance should be a priority.
