北方猪尾猕猴(NPM)缺乏TRIM 5 α,一种抗病毒限制因子,而是具有TRIM 5-CypA。在我们之前的研究中,我们证明了HIV-1 NL 4 −3成功感染了NPM,并在体内形成了一个长期的病毒库。然而,HIV-1感染的NPM在感染的前6周表现出相对较高的病毒血症,此后病毒血症下降,表明这些动物中的HIV-1 NL 4 −3感染只是部分允许的。因此,为了优化NPM中的HIV-1感染,我们生成了HIV-1 NL 4 − R3 A和stHIV-1 sv,并用这些病毒感染NPM。HIV-1 NL 4-R3 A和stHIV-1 sv可以在41周的急性感染阶段在NPM中持续复制。与HIV-1 NL 4 − R3 A相比,stHIV-1 sv的复制水平明显更高,感染后者的NPM诱导了更强大的中和抗体,但细胞免疫应答较弱。另外,随着病毒复制,IFN-I信号显著上调,且在stHIV-1 sv感染的猕猴中更高。结果表明,SIV的vif基因可拮抗APOBEC 3蛋白在NPMs中的抗病毒作用。总之,感染HIV-1 NL 4 − R3 A和stHIV-1 sv的NPM表现出不同的病毒学和免疫学特征。此外,干扰素相关基因表达可能在控制NPM中的原发性HIV-1 NL 4-R3 A和stHIV-1 sv复制中发挥作用。这一结果表明NPM是一种潜在的HIV/AIDS动物模型。
The northern pig-tailed macaques (NPMs) lack TRIM5α, an antiviral restriction factor, and instead have TRIM5-CypA. In our previous study, we demonstrated that HIV-1NL4−3 successfully infected NPMs and formed a long-term viral reservoir in vivo. However, the HIV-1-infected NPMs showed relatively high viremia in the first 6 weeks of infection, which declined thereafter suggesting that HIV-1 NL4−3 infection in these animals was only partly permissive. To optimize HIV-1 infection in NPMs therefore, we generated HIV-1NL4−R3A and stHIV-1sv, and infected NPMs with these viruses. HIV-1NL4−R3A and stHIV-1sv can replicate persistently in NPMs during 41 weeks of acute infection stage. Compared to the HIV-1NL4−R3A, stHIV-1sv showed a notably higher level of replication, and the NPMs infected with the latter induced a more robust neutralizing antibody but a weaker cellular immune response. In addition, IFN-I signaling was significantly up-regulated with the viral replication, and was higher in the stHIV-1sv infected macaques. Consequently, the sequences of pro-viral env showed fewer G-A hyper-mutations in stHIV-1sv, suggesting that vif gene of SIV could antagonize the antiviral effects of APOBEC3 proteins in NPMs. Taken together, NPMs infected with HIV-1NL4−R3A and stHIV-1sv show distinct virological and immunological features. Furthermore, interferon-related gene expression might play a role in controlling primary HIV-1NL4−R3A and stHIV-1sv replication in NPMs. This result suggests NPM is a potential HIV/AIDS animal model.
