    • First generation adenoviral vectors and associated recombinant adenovirus-based HIV vaccines which show enhanced stability and growth properties and greater cellular-mediated immunity are described within this specification. These adenoviral vectors are utilized to generate and produce through cell culture various adenoviral-based HIV-1 vaccines which contain HIV-1 gag, HIV-1 pol and/or HIV-1 nef polynucleotide pharmaceutical products, and biologically relevant modifications thereof. These adenovirus vaccines, when directly introduced into living vertebrate tissue, preferably a mammalian host such as a human or a non-human mammal of commercial or domestic veterinary importance, express the HIV1-Gag, Pol and/or Nef protein or biologically modification thereof, inducing a cellular immune response which specifically recognizes HIV-1. The exemplified polynucleotides of the present invention are synthetic DNA molecules encoding HIV-1 Gag, encoding codon optimized HIV-1 Pol, derivatives of optimized HIV-1 Pol (including constructs wherein protease, reverse transcriptase, RNAse H and integrase activity of HIV-1 Pol is inactivated), HIV-1 Nef and derivatives of optimized HIV-1 Nef, including nef mutants which effect wild type characteristics of Nef, such as myristylation and down regulation of host CD4. The adenoviral vaccines of the present invention, when administered alone or in a combined modality regime, will offer a prophylactic advantage to previously uninfected individuals and/or provide a therapeutic effect by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV-1 infection.
    • 在本说明书中描述了显示增强的稳定性和生长特性以及更大的细胞介导的免疫的第一代腺病毒载体和相关重组腺病毒的HIV疫苗。 这些腺病毒载体用于通过细胞培养产生和产生各种含有HIV-1 gag,HIV-1 pol和/或HIV-1 nef多核苷酸药物产品的基于腺病毒的HIV-1疫苗及其生物相关的修饰。 这些腺病毒疫苗当直接引入活的脊椎动物组织中时,优选哺乳动物宿主例如具有商业或家庭兽医重要性的人或非人哺乳动物,表达HIV1-Gag,Pol和/或Nef蛋白或其生物修饰, 诱导特异性识别HIV-1的细胞免疫应答。 本发明的示例性多核苷酸是编码HIV-1Gag的编码密码子优化的HIV-1 Pol的合成DNA分子,其优化的HIV-1 Pol的衍生物(包括其中蛋白酶,逆转录酶,RNAse H和HIV-1的整合酶活性 Pol被灭活),HIV-1 Nef和优化的HIV-1 Nef的衍生物,包括影响Nef野生型特征的nef突变体,如主体CD4的肉豆蔻酰化和下调。 本发明的腺病毒疫苗当单独施用或以组合的方式给药时,将对先前未感染的个体提供预防优势,和/或通过减少被感染个体内的病毒载量水平提供治疗效果,从而延长无症状期 HIV-1感染。

    • Pharmaceutical compositions which comprise HIV Nef DNA vaccines are disclosed, along with the production and use of these DNA vaccines. The nef-based DNA vaccines of the invention are administered directly introduced into living vertebrate tissue, preferably humans, and express the HIV Nef protein or biologically relevant portions thereof, inducing a cellular immune response which specifically recognizes human immunodeficiency virus-1 (HIV-1). The DNA molecules which comprise the open reading frame of these DNA vaccines are synthetic DNA molecules encoding codon optimized HIV-1 Nef and derivatives of optimized HIV-1 Nef, including nef modifications comprising amino terminal leader peptides, removal of the amino terminal myristylation site, and/or modification of the Nef dileucine motif. These modifications may effect wild type characteristics of Nef, such as myristylation and down regulation of host CD4.
    • 公开了包含HIV Nef DNA疫苗的药物组合物以及这些DNA疫苗的生产和使用。 将本发明的基于nef的DNA疫苗直接施用于活的脊椎动物组织,优选人,并且表达HIV Nef蛋白或其生物相关部分,诱导特异性识别人免疫缺陷病毒-1(HIV-1 )。 构成这些DNA疫苗的开放阅读框架的DNA分子是编码密码子优化的HIV-1 Nef和优化的HIV-1 Nef的衍生物的合成DNA分子,包括包含氨基末端前导肽的nef修饰,氨基末端的肉豆蔻酰化位点的去除, 和/或Nef二氨基酸基序的修饰。 这些修饰可能会影响Nef的野生型特征,如主要病毒的肉豆蔻酰化和下调。
