摘要:
Method for the in vitro screening of compounds that inhibit Env glycoprotein incorporation into HIV-1 virions in cells infected by a HIV-1 virus, wherein said method comprises the following steps a) determining the ability of a candidate compound to inhibit the interaction between (i) the HIV-1 Gag protein and (ii) the TIP47 protein; and b) selecting positively the candidate compound(s) that inhibit the interaction between (i) the HIV-1 Gag protein and (ii) the TIP47 protein.
摘要:
A method to evaluate the sensitivity of an HIV variant from a biological sample to at least one drug able to inhibit the HIV protease is disclosed. The method comprises the steps of: a) amplifying the nucleic acid encoding the HIV protease from the biological sample, to obtain an amplified HIV protease coding sequence; b) cloning the amplified HIV protease coding sequence into a unique restriction site of a modified HIV molecular clone, wherein said modified HIV molecular clone is modified at least by deleting the protease coding sequence and by replacing it with the unique restriction site, to obtain a recombinant HIV molecular clone comprising and expressing the HIV protease coding sequence; c) introducing the recombinant HIV molecular clone comprising and expressing the HIV protease coding sequence into cultured cells, to obtain recombinant HIV transfected cells; d) measuring the level of HIV p24 antigen into the cell supernatant of the recombinant HIV transfected cells both in the presence and in the absence of the drug able to inhibit the HIV protease. The method is suitable for any HIV variant, both HIV-1 or HIV-2 variants. Diagnostic kits are also disclosed.
摘要:
The invention relates generally to immunoassays for detection of antibodies by use of chemiluminescent compounds. More particularly, the invention relates to chemiluminescent immunoassays to detect antibodies wherein a precomplex mixture is created and a two-step assay is performed resulting in a greater signal.
摘要:
Monoclonal neutralizing antibodies are disclosed that specifically bind to the HIV-1 gp41 membrane-proximal external region (MPER). Also disclosed are compositions including the disclosed antibodies that specifically bind gp41, nucleic acids encoding these antibodies, expression vectors including the nucleic acids, and isolated host cells that express the nucleic acids. The antibodies and compositions disclosed herein can be used for detecting the presence of HIV-1 in a biological sample, or detecting an HIV-1 infection or diagnosing AIDS in a subject. In additional, the broad neutralization breadth of the disclosed antibodies makes them ideal for treating a subject with an HIV infection. Thus, disclosed are methods of treating and/or preventing HIV infection.
摘要:
The invention relates to the use of at least one sub-unit of a translation elongation factor 1, EF-1, protein, of a homologue thereof, or of a C-terminal fragment of said protein and homologue, as an agent for detecting a p24 retroviral protein, or a homologue thereof.
摘要:
The invention relates to peptides comprising part or all of a conserved element within a Center-of Tree (COT) sequence derived from a family of polypeptides encoded by naturally occurring variants of HIV. The invention also relates to immunogenic compositions and vaccines comprising said peptides. The invention also relates to methods for the identification of HIV controller patients based on the detection of the T cells of the patient to mount a cytotoxic T cell response against said peptides and to methods for the identification of immunogenic peptides within a family of variant polypeptides.
摘要:
Novel quinoline inhibitors of retroviral integrase, particularly HIV-1 integrase. The quinoline inhibitors are oxoquinolines of the following formula (I) that can be used for preventing or treating AIDS or HIV infection in a subject. Wherein Z is selected from -C(O)OR2 then at least one of R3, R4, R5 or R6 is -C(O)CH2C(O)X and wherein R1, R2, R3, R5, R6 or X are as disclosed herein.
