动物模型在预防和治疗COVID-19的疫苗/药物的快速开发中发挥着至关重要的作用,但目前的模型在研究SARS-CoV-2在某些特殊组织或器官上的发病机制时存在一些缺陷。在这里,我们构建了人类 ACE2 和 SARS-CoV-2 NF/F 敲入小鼠系,该小鼠系组成型表达人类 ACE2,并特异性表达由 Cre 重组酶诱导的 SARS-CoV-2 N 基因。通过与允许肺特异性和组成型表达的 Cre 转基因系杂交,我们产生了肺特异性 (Sftpc-hACE2-NF/F) 和组成型 SARS-CoV-2 N (EIIa-hACE2-NF/F) 表达小鼠。在鼻内感染只能在 SARS-CoV-2 N 表达细胞中复制的 SARS-CoV-2 GFP/ΔN 菌株后,我们证明 Sftpc-hACE2-NF/F 和 EIIa-hACE2-NF/F 小鼠都支持病毒复制。与我们的设计一致,病毒复制仅限于 Sftpc-hACE2-NF/F 小鼠的肺组织,而 EIIa-hACE2-NF/F 小鼠在多个组织中发生感染。此外,我们的模型支持不同的SARS-CoV-2变体感染,并且可以成功用于评估治疗性单克隆抗体(Ab1F11)和抗病毒药物(Molnupiravir)的效果。最后,为了测试 SARS-CoV-2 感染对雄性生殖的影响,我们通过与 AMH-Cre 转基因系杂交产生了支持细胞特异性 SARS-CoV-2 N 表达的小鼠。我们发现SARS-CoV-2 GFP/ΔN株可以感染支持细胞,由于血睾屏障被破坏而导致生精缺陷。总体而言,结合不同组织特异性的Cre转基因系,人类ACE2和SARS-CoV-2 NF/F系使我们能够评估体内抗病毒药物并研究SARS-CoV-2在某些特殊组织或器官上的发病机制。
Animal models play crucial roles in the rapid development of vaccines/drugs for the prevention and therapy of COVID-19, but current models have some deficits when studying the pathogenesis of SARS-CoV-2 on some special tissues or organs. Here, we generated a human ACE2 and SARS-CoV-2 NF/F knockin mouse line that constitutively expresses human ACE2 and specifically expresses SARS-CoV-2 N gene induced by Cre-recombinase. By crossing with Cre transgenic lines allowing for lung-specific and constitutive expression, we generated lung-specific (Sftpc-hACE2-NF/F) and constitutive SARS-CoV-2 N (EIIa-hACE2-NF/F) expressing mice. Upon intranasal infection with a SARS-CoV-2 GFP/ΔN strain which can only replicate in SARS-CoV-2 N expressed cells, we demonstrated that both the Sftpc-hACE2-NF/F and EIIa-hACE2-NF/F mice support viral replication. Consistent with our design, viral replication was limited to the lung tissues in Sftpc-hACE2-NF/F mice, while the EIIa-hACE2-NF/F mice developed infections in multiple tissues. Furthermore, our model supports different SARS-CoV-2 variants infection, and it can be successfully used to evaluate the effects of therapeutic monoclonal antibodies (Ab1F11) and antiviral drugs (Molnupiravir). Finally, to test the effect of SARS-CoV-2 infection on male reproduction, we generated Sertoli cell-specific SARS-CoV-2 N expressed mice by crossing with AMH-Cre transgenic line. We found that SARS-CoV-2 GFP/ΔN strain could infect Sertoli cells, led to spermatogenic defects due to the destruction of blood-testis barrier. Overall, combining with different tissue-specific Cre transgenic lines, the human ACE2 and SARS-CoV-2 NF/F line enables us to evaluate antivirals in vivo and study the pathogenesis of SARS-CoV-2 on some special tissues or organs.
