The research results of Retrovirus, Filovirus, Orthomyxovirus and Paramyxovirus showed that 6-helix bundle formed by heptad repeat regions of fusion proteins was the key to start membrane fusion.

对反转录病毒、纤丝病毒、正粘病毒和副粘病毒等的研究表明，其囊膜表面融合蛋白的七肽重复区HR1和HR2相互作用形成六螺旋束是引发膜融合的关键。

The N- and C-terminal heptad repeat (designated NHR and CHR, respectively) regions of gp41 extracellular domain can form a six-helix bundle by interaction, which brings both the viral and target cell membranes into proximity for fusion.

因此，任何化合物如能抑制NHR和CHR的结合，使六螺旋束结构不能形成，就能阻止病毒进入靶细胞，从而保护免疫细胞不被感染。

The interaction between the N- and C-terminal heptad repeat regions of the gp41 extracellular domain leads to the formation of a six-helix bundle (6-HB), representing the fusion-active gp41 core.

当gp120与靶细胞表面的CD4及共受体结合后，gp41胞外段N-末端重复序列与C—术端重复序列相互作用，形成六螺旋束(6—HB)，即gp41融合活性核心，从而导致病毒融合。
