The invention belongs to the field of pharmaceutical and biological engineering, and relates to a CRISPR/Cas9 recombinant lentiviral vector for human immunodeficiency virus gene therapy and a lentivirus of the CRISPR/Cas9 recombinant lentiviral vector. The recombinant lentiviral vector is prepared by carrying out enzyme digestion on a lentiviral vectorlentiCRISPR by BsmBI and connecting into a BsmBI cohesive end-containing CXCR4 specific target sequence to recombine; the obtained CRISPR/Cas9 recombinant lentiviral vector is capable of mutating gene sequences at four different loci of ahuman immunodeficiency virusco-receptor CXCR4 and themutatuin rate is high and up to 25-75%. The cells transformed by the recombinant lentiviral vector cannot be infected by the human immunodeficiency virus. Compared with theRNAi-Knockdown, ZFN and TALEN technologies, the method has higher efficiency of suppressing the human immunodeficiency virus replication; the system is rapid to construct, simple and low in cost, is capable of preventing the invasion of the human immunodeficiency virus and is suitable for human immunodeficiency virus gene therapy.

Immunogenic compositions containing a human immunodeficiency virus (HIV) gp140 protein, sorbitol, polysorbate 20, and histidine buffer are described. The described immunogenic compositions are advantageous in that they are stable at refrigerated temperature for extended periods of time, and are compatible with an adjuvant. Also described are methods of using the immunogenic compositions to induce an immune response against an HIV in a subject. The immunogenic compositions can be administered alone, or in combination with one or more additional HIV antigens, or one or more adenovirus vectors encoding the one or more additional HIV antigens.

Methods and compositions for treatment of human immunodeficiency virus (HIV) infections have been developed which dampen immune activation with a bias more on the CD4 T cells relative to the CD8 T cell response, inhibit HIV replication, reactivate latent HIV, and inhibit infection of cells by HIV. Pushing latent HIV into active infections with hindrance of cell infection by the reactivated HIV can substantially reduce the number of cells infected with HIV and the viral load of HIV, which is not achieved using just the combination of ART and compounds which activate latent HIV. The methods involve administering to an HIV-infected subject three or more compounds which collectively dampen immune activation with a bias more on the CD4 T cells relative to the CD8 T cell response, inhibit HIV replication, reactivate latent HIV, and inhibiting infection of CD4 T cells by HIV.
