美国科学家近日开发出一种新的显微镜技术,能够只“照亮”细胞的表面。利用这一技术,科学家首次实时、清晰地观察到了无数分子在活细胞中形成单个HIV粒子的过程。这一成果将可能在开发艾滋病治疗方案方面提供帮助,并将改变艾滋病研究者的思考方式。相关论文2008年5月25日在线发表于《自然》(Nature)杂志上。
用傅里叶变换红外光谱技术研究HIV-1融合肽的插膜深度与角度

为探讨HIV-1gp41N端融合肽诱导膜融合的机理,利用傅里叶变换红外光谱技术研究了化学方法合成的代表HIV-1gp41N末端的23肽(HIVWT)分别与酸性POPG和中性POPC脂膜作用后,多肽H/D交换程度的变化及其在膜中的取向。结果表明,HIVWT分子中的大部份氨基酸残基被POPG脂膜保护,分子骨架上的酰胺质子只有11.9%可被D交换,而HIVWT被POPC脂膜保护的程度则小得多;在POPG...
HIV-1进攻靶细胞的机制及相应环节抑制剂

HIV-1是导致获得性免疫缺陷综合症(AIDS)的流行最广、破坏力最强的病毒。HIV-1分两个步骤特异性地进攻CD4+细胞:一是利用表面糖蛋白gp120和靶细胞膜上的受体结合;二是通过跨膜糖蛋白gp41使病毒的包膜和靶细胞的质膜发生融合。经过上述步骤,病毒的核心蛋白和遗传物质得以进入人体细胞,在其中进行复制,同时,细胞膜的稳定性被破坏,细胞的内外环境失去平衡,最终导致细胞死亡。HIV-1进攻靶细胞...
