描述(由申请人提供):有效的 HIV-1 疫苗可能需要 CTL 诱导成分。迄今为止,只有重组腺病毒 5 疫苗是此类成分的候选者,但它面临着载体免疫方面的重大问题,并且进入粘膜组织的能力未知。纳米颗粒作为疫苗载体具有一些优势,但面临免疫原性、致癌性和制造质量问题。 该提案探讨了使用由自体人类蛋白质组成的生物纳米颗粒(“金库”),装载 HIV-1 序列作为疫苗。穹窿已被证明对 CTL 反应具有免疫原性并可进入粘膜免疫系统。此外,它们由通常存在于细胞质中的自身蛋白组成,因此不应具有免疫原性或致癌性,并且易于生产且质量稳定。这两个目标是: 目标 1:创建携带保守的 HIV-1 蛋白序列的靶向库; 目标 2:确认系统和粘膜免疫区室中穹窿的免疫原性。
英文摘要
DESCRIPTION (provided by applicant): It is likely that a CTL-eliciting component will be required for an effective HIV-1 vaccine. To date, only the recombinant adenovirus-5 vaccine has been a candidate for such a component, but it faced significant issues with vector immunity and had unknown capacity to access mucosal tissues. Nanoparticles offer some advantages as vaccine vectors, but face problems with immunogenicity, carcinogenicity, and manufacturing quality. This proposal explores the use of biological nanoparticles ("vaults") composed of autologous human proteins, loaded with HIV-1 sequences to serve as a vaccine. Vaults have been shown to be immunogenic for CTL responses and access the mucosal immune system. Additionally, they are composed of self-proteins that are normally found in the cytoplasm and therefore should not be immunogenic or carcinogenic, and are readily manufactured with consistent quality. The two aims will be: Aim 1: To create targeted vaults carrying conserved HIV-1 protein sequences; Aim 2: To confirm the immunogenicity of the vaults in systemic and mucosal immune compartments.
