摘要： The present invention provides several classes of compounds which can be used to inactivate retroviruses, such as HIV-1, by attacking the CCHC zinc fingers of the viral nucleocapsid protein and ejecting the zinc therefrom. In addition, kits for identifying compounds that can react with CCHC zinc fingers of the nucleocapsid proteins of a large number of different retroviruses have also been developed. The kits of the present invention describe a set of specific tests and reagents that can be used to screen and identify compounds based on their ability to react with and disrupt retroviral zinc fingers in the viral NC proteins and, in turn, inactivate the retrovirus of interest.

摘要： An antigen capture method, and an antigen capture assay diagnostic kit, for detecting the presence or concentration of HIV in a biological sample without interference from antigen-antibody immune complexes is provided. The lysate of a biological sample obtained from an animal is contacted with a detectable mount of an antibody specifically reactive with the nucleocapsid p7 antigen or an immunoreactive fragment of the p7 antigen for a time and under conditions sufficient for p7 antigen contained in the lysate to form a p7-antibody complex. The presence or concentration of this p7-antibody complex is determined to detect or quantitate the presence of HIV in the biological sample. Uses of this assay and method include detecting the presence of HIV infection in an infant born to an HIV-infected mother, monitoring the progression of HIV infection, and evaluating the effectiveness of an anti-HIV treatment administered to an animal, such as a human. Purified antibodies specifically reactive with an immunoreactive epitope specific to p7 or an immunoreactive fragment of p7 are also provided as well as an antigen capture method for detecting the presence of a lentivirus in a biological sample involving the nucleocapsid protein of the lentivirus.

摘要： The present invention defines a biological role for the following sequence of amino acids that is found in the nucleocapsid domain of the gag precursor polyproteins of all replication-competent retroviruses: -Cys-X-X-Cys-X-X-X-X-His-X-X-X-X-Cys- wherein X represents variable amino acids. The invariant residues constitute part of a vital protein structure, at least one of which are found in all retroviruses and which are involved in the selection and packaging of genomic viral RNA into infectious virus particles. Disruption of this structure leads to the formation of virus-like particles which appear to be structurally normal, but which do not contain the normal complement of viral RNA. Therefore, their infectivity is drastically reduced or completely eliminated. The infectivity of any retrovirus, including human retroviruses, and more particularly human immunodeficiency virus (HIV), can be drastically reduced or completely eliminated by generating mutants that lack some or all of the invariant residues required to form the structure. In addition, any means of disrupting the function of this array will in turn disrupt the viral life cycle. Thus, with the knowledge provided by this invention, chemotherapeutic reagents aimed toward this array may be devised.
摘要翻译： 本发明限定了所有复制型逆转录病毒的gag前体多蛋白的核衣壳结构域中发现的以下氨基酸序列的生物学作用：-Cys-XX-Cys-XXXX-His-XXXX-Cys-，其中X 代表可变氨基酸。 不变残基构成重要蛋白质结构的一部分，其中至少一个存在于所有逆转录病毒中，并且参与将基因组病毒RNA选择和包装到感染性病毒颗粒中。 这种结构的破坏导致病毒样颗粒的形成，其似乎在结构上是正常的，但不包含病毒RNA的正常补体。 因此，它们的感染性大大降低或完全消除。 任何逆转录病毒（包括人类逆转录病毒，特别是人类免疫缺陷病毒（HIV））的感染性可以通过产生缺少形成结构所需的一些或全部不变残基的突变体而被大大降低或完全消除。 此外，破坏此阵列功能的任何方法将反过来破坏病毒生命周期。 因此，利用本发明提供的知识，可以设计针对这种阵列的化学试剂。
