    • The present invention concerns a method for prophylactic and/or therapeutic vaccination and/or treatment and/or diagnosis of HIV/AIDS, other infectious diseases, inflammatory and angiogenic diseases and tumours which utilizes a biologically active HIV-1 Tat protein, fragments or derivates thereof, as a module with one or more of the following features: antigen, adjuvant and targeting-delivery system to specific antigen-presenting cells including dendritic cells, endothelial cells and macrophages. In particular, it is claimed that Tat can be used only in its biologically active form as an antigen combined with one or more other antigens, to prime or to boost protective immune responses against itself as well as other antigens and/or to selectively deliver these antigen(s) as well as active compounds to dendritic cells, endothelial cells and macrophages, due to its capability of targeting these A PC and of activating their maturation and functions and of increasing Th-1 type immune responses as an adjuvant. Therefore, due to these characteristics and to the distribution of these cells in the body (during physiological and pathological disorders), biologically active Tat, fragments or derivates thereof containing the RGD region, can be used for preventive, therapeutic and/or diagnostic purposes for HIV/AIDS, other infectious diseases, inflammatory and angiogenic diseases and tumors.
    • 本发明涉及一种用于预防和/或治疗预防和/或治疗和/或诊断艾滋病毒/艾滋病,其他感染性疾病,炎症和血管生成疾病和肿瘤的方法,其利用生物活性的HIV-1 Tat蛋白,片段或衍生物 作为具有以下特征中的一个或多个的模块:抗原,佐剂和靶向递送系统到特定抗原呈递细胞,包括树突状细胞,内皮细胞和巨噬细胞。 特别地,据称Tat可以仅以其生物活性形式用作与一种或多种其它抗原组合的抗原,以引发或增强针对其自身以及其他抗原的保护性免疫应答和/或选择性地递送这些 抗原以及由树突状细胞,内皮细胞和巨噬细胞组成的活性化合物,由于其能够靶向这些A PC并激活其成熟和功能以及增加作为佐剂的Th-1型免疫应答。 因此,由于这些特征和这些细胞在体内的分布(在生理和病理障碍期间),含有RGD区的生物活性的Tat,其片段或衍生物可用于预防,治疗和/或诊断目的 艾滋病毒/艾滋病,其他传染病,炎症和血管生成疾病和肿瘤。

    • The present invention refers to Tat as the active principle for a prophylactic and/or therapeutic vaccine against HIV infection, the progression towards AIDS and the development of tumors and other syndromes and symptoms in subjects infected by HIV. Tat is in biologically active form either as recombinant protein or peptide or as DNA. More particularly, the invention refers to a vaccine based on HIV-1 Tat as immunogen, inoculated as DNA and/or recombinant protein or as peptides, alone or in combination with other genes or viral gene products (Nef, Rev, Gag) or parts thereof, or in combination with various immuno-modulant cytokines (IL-12, IL-15) or with the gene coding for an immuno-modulant cytokine or part thereof. Tat, Nef, Rev, Gag and the immuno-modulant cytokines are administrated both as a mixture of recombinant proteins, peptides or fusion proteins (Tat/Nef, Tat/Rev, Tat/Gag, Tat/IL-12, Tat/IL-15) or as plasmid DNA.
    • 本发明涉及Tat作为针对HIV感染的预防和/或治疗性疫苗的活性成分,艾滋病的进展以及感染HIV的受试者的肿瘤和其他综合征和症状的发展。 Tat作为重组蛋白或肽或DNA作为生物活性形式。 更具体地,本发明涉及基于作为免疫原的HIV-1 Tat的疫苗,作为DNA和/或重组蛋白或作为肽单独接种或与其它基因或病毒基因产物(Nef,Rev,Gag)或部分 或与各种免疫调节细胞因子(IL-12,IL-15)组合或与编码免疫调节性细胞因子或其部分的基因组合。 Tat,Nef,Rev,Gag和免疫调节细胞因子作为重组蛋白,肽或融合蛋白的混合物(Tat / Nef,Tat / Rev,Tat / Gag,Tat / IL-12,Tat / IL- 15)或作为质粒DNA。
