宿主-病毒的共同进化关系如何表现是病毒学中最有趣的问题之一。为了解决这个问题,哺乳动物-慢病毒的关系可以被认为是细胞和病毒蛋白的相互作用,特别是载脂蛋白B mRNA编辑酶催化多肽样3(APOBEC 3)和病毒感染因子(Vif)。APOBEC 3酶促限制慢病毒复制,而Vif拮抗APOBEC 3介导的宿主抗病毒作用。在这项研究中,重点是猫APOBEC 3蛋白与猫和美洲狮中的两种猫免疫缺陷病毒之间的相互作用。据我们所知,这项研究提供了非灵长类慢病毒Vif无法抵消天然宿主通过APOBEC 3蛋白介导的抗病毒活性的第一个证据。
How host–virus co‐evolutionary relationships manifest is one of the most intriguing issues in virology. To address this topic, the mammal–lentivirus relationship can be considered as an interplay of cellular and viral proteins, particularly apolipoprotein B mRNA editing enzyme catalytic polypeptide‐like 3 (APOBEC3) and viral infectivity factor (Vif). APOBEC3s enzymatically restrict lentivirus replication, whereas Vif antagonizes the host anti‐viral action mediated by APOBEC3. In this study, the focus was on the interplay between feline APOBEC3 proteins and two feline immunodeficiency viruses in cats and pumas. To our knowledge, this study provides the first evidence of non‐primate lentiviral Vif being incapable of counteracting a natural host's anti‐viral activity mediated via APOBEC3 protein.
