人体免疫缺陷病毒(艾滋病毒)已经感染了全世界数百万人,并继续成为一个主要的全球健康问题。科学家们需要一个小动物模型来研究HIV的发病机制和免疫反应。为此,通过将人类细胞和/或组织移植到免疫缺陷小鼠体内来重建人类免疫系统,从而创建了人源化小鼠。因此,人源化小鼠已成为艾滋病研究人员的重要动物模型,但也存在一些局限性。目前传统人源化小鼠易因小鼠信号调节蛋白α和CD47信号通路诱导的移植物抗宿主病而死亡。此外,常用的人源化小鼠产生低水平的人类细胞因子,这是强大的骨髓和自然杀伤细胞发育和功能所必需的。在这里,我们描述了人源化程序和转基因和敲入免疫缺陷小鼠的最新进展,以解决这些限制。
Human immunodeficiency virus (HIV) has infected millions of people worldwide and continues to be a major global health problem. Scientists required a small animal model to study HIV pathogenesis and immune responses. To this end, humanized mice were created by transplanting human cells and/or tissues into immunodeficient mice to reconstitute a human immune system. Thus, humanized mice have become a critical animal model for HIV researchers, but with some limitations. Current conventional humanized mice are prone to death by graft versus host disease induced by the mouse signal regulatory protein α and CD47 signaling pathway. In addition, commonly used humanized mice generate low levels of human cytokines required for robust myeloid and natural killer cell development and function. Here, we describe recent advances in humanization procedures and transgenic and knock-in immunodeficient mice to address these limitations.
