重建人类免疫系统的小鼠有助于研究HIV-1的发病机制和治疗方法。自然杀伤(NK)细胞一直被认为是先天抗hiv反应的关键介质。然而,已建立的人源化小鼠模型不支持从移植的人造血干细胞(hsc)中生长出强大的人NK细胞。人类NK细胞重建的主要障碍是缺乏人类白细胞介素-15 (IL-15)信号,因为小鼠IL-15是人类IL-15受体的不良刺激物。在这里,我们证明免疫缺陷的NOD。表达人IL-15转基因基因(NSG- tg (IL-15))的Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG)小鼠具有生理水平的人IL-15,并且在与人脐带血来源的造血干细胞移植时支持人NK细胞的长期植入。这些Hu-NSG-Tg(IL-15)小鼠表现出与人类免疫细胞的强大和长期重建,但不发生移植物抗宿主病(GVHD),允许对人类NK细胞进行长期研究。最后,我们发现这些移植了HSC的小鼠可以维持HIV-1感染,从而在hiv感染的小鼠中产生人类NK细胞反应。我们得出结论,Hu-NSG-Tg(IL-15)小鼠是研究NK细胞对HIV-1反应的一个强大的新模型。
Mice reconstituted with human immune systems are instrumental in the investigation of HIV-1 pathogenesis and therapeutics. Natural killer (NK) cells have long been recognized as a key mediator of innate anti-HIV responses. However, established humanized mouse models do not support robust human NK cell development from engrafted human hematopoietic stem cells (HSCs). A major obstacle to human NK cell reconstitution is the lack of human interleukin-15 (IL-15) signaling, as murine IL-15 is a poor stimulator of the human IL-15 receptor. Here, we demonstrate that immunodeficient NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice expressing a transgene encoding human IL-15 (NSG-Tg(IL-15)) have physiological levels of human IL-15 and support long-term engraftment of human NK cells when transplanted with human umbilical-cord-blood-derived HSCs. These Hu-NSG-Tg(IL-15) mice demonstrate robust and long-term reconstitution with human immune cells, but do not develop graft-versus-host disease (GVHD), allowing for long-term studies of human NK cells. Finally, we show that these HSC engrafted mice can sustain HIV-1 infection, resulting in human NK cell responses in HIV-infected mice. We conclude that Hu-NSG-Tg(IL-15) mice are a robust novel model to study NK cell responses to HIV-1.
