人免疫缺陷病毒(HIV)和来自猕猴的猿猴免疫缺陷病毒(SIVmac)分别是获得性免疫缺陷综合征(AIDS)和猿猴AIDS的病原体(Barré-Sinoussi et al.,1983; Gallo等人,1984; Levy等人,1984; Clavel等人,1986; Letvin等人,1985; De Vita等人,1988年)。SIVmac的基因序列与HIV-2(Chakrabarti等人,1987)和HIV-1(Chakrabarti等人,1987; Desrosiers,1988),并且SIVmac感染猕猴代表了人类AIDS的最佳动物模型。这些病毒进入其宿主细胞的分子和细胞机制还不清楚。在HIV-1包膜与细胞膜融合之前的内吞步骤的参与以及融合对酸性pH的要求是有争议的话题(Maddon等人,1986,1988; Stein等人,1987; Pauza和Price,1988;麦克卢尔等人,1988年)。
Human immunodeficiency virus (HIV) and simian immunodeficiency virus from macaques (SIVmac) are the etiological agents of the acquired immunodeficiency syndrome (AIDS), and simian AIDS, respectively (Barré-Sinoussi et al., 1983; Gallo et al, 1984; Levy et al, 1984; Clavel et al., 1986; Letvin et al., 1985; De Vita et al., 1988). The genetic sequence of SIVmacis closely related to that of HIV-2 (Chakrabarti et al, 1987) and HIV-1 (Chakrabarti et al., 1987; Desrosiers, 1988), and infection of macaques by SIVmacrepresents the best animal model for human AIDS. The molecular and cellular mechanisms of entry of these viruses into their host cells are not well understood. The involvement of an endocytosis step before the fusion of the HIV-1 envelope with cellular membranes, and the requirement for acidic pH for fusion are topics of controversy (Maddon et al., 1986, 1988; Stein et al., 1987; Pauza and Price, 1988; McClure et al., 1988).
