Abstract: The present invention provides nucleic acid, vectors, viruses, and recombinant cells comprising triple-stranded structures, such as those resulting from central initiation and termination of HIV-1 reverse transcription at the center of HIV-1 linear DNA genomes. These triplex structures can act as a cis-determinant of HIV-1 DNA nuclear import, allowing infection of non-dividing target cells. In one aspect, the presence of the DNA triplex sequence in an HIV vector strongly stimulates gene transfer in hematopoietic stem cells. The invention also provides methods of using these triplex structures for making recombinant cells, as well as methods of using the recombinant cells to express proteins of interest both in vitro and in vivo.

Abstract: The present invention relates to a compound inducing activation of HLA-E-restricted CD8 T cells and/or NK cells in a human subject, and reducing HIV viral load, such as glatiramer acetate and glatiramer acetate related active substances and products, for use in the treatment of HIV infection. Macaques chronically infected by SIV have been treated with glatiramer acetate. One of the animals had already progressed to the stage of AIDS. We injected 18mg of glatiramer acetate three times per week for only 2 weeks. Surprisingly, a strong impact on viral load was observed in response to the treatment. Viremia decreased by 1 log during glatiramer acetate treatment. Even more surprising was the fact that this decrease persisted after stopping the treatment reaching almost a 2 logs decrease in one animal. This is a major result as compared to cART as stopping cART leads to a rebound of the viral load within days.

Abstract: The present invention provides an immunoassay leading to the rapid and simultaneous detection of antibodies to a wide range of infectious pathogens in biological fluids of infected patients. This immunoassay involves the covalent and oriented coupling of fusion proteins comprising an AGT enzyme and a viral antigen on an identifiable solid support (e.g. fluorescent microspheres). The thus obtained antigen-coupled microspheres show enhanced capture of specific antibodies as compared to antigen-coupled microspheres produced by standard amine coupling procedures.

It also concerns a process for the preparation of these multimeric RNPs or recombinant yeasts or yeast lysates. In particular, the present invention relates to their use as active ingredient for the in vitro production of an immunogenic composition or in eliciting a protective prophylactic or a therapeutic immune response against said heterologous polypeptide in a host in need thereof. Recombinant yeasts or yeast lysates of the invention can also be used as expression and vector systems for delivery to a host.
