Abstract: We have developed a series of Ebola vims envelope glycoprotein (EboGP)-based chimeric fusion proteins that are still able to maintain an efficient EboGP-mediated virus entry in various cell types including human antigen-presenting cells (APCs) while presenting large viral polypeptides, such as HIV Env v3-v5 domain (as large as 241 aa), at the apex and the sides of each EboGP monomer to elicit robust host immune responses. This invention demonstrates the feasibility of an EboGP-based chimeric fusion technology as a novel vaccine approach against different microbial pathogens, including that in human and animals, and against cancers.

Abstract: A device for repeated intradermal injections within an organic tissue. The device comprises a support defining an internal housing for receiving a vial containing an aqueous solution, a source of pressurized air in fluid communication with the vial, a tube defining a pressurized solution path, a hollow injection needle, an injection head, a driven element with a distal end connected to the injection head, an actuator connected to the driven element, and a valve in fluid communication with the pressurized solution path for controlling a flow of the pressurized solution into the tube from the vial up to the distal end of the hollow injection needle.

Abstract: The present disclosure relates to DNA vaccines against Crimean-Congo Hemorrhagic Fever (CCHF) virus. The present disclosure also relates to CCHF virus sequences and their use for vaccination such as DNA vaccination. The present disclosure more particularly relates to artificial nucleic acid molecules that are able to encode a CCHF polypeptide of an infectious CCHF virus, a fragment or a variant thereof. The nucleic acid molecules of the present application are formulated as immunogenic compositions.

Abstract: The present disclosure provides vectors that allow efficient expression of transgenes. The vector of the present disclosure may be used to express proteins or peptides of interest into a host's cells and to trigger an immune response towards an antigenic portion of the proteins or peptides in a mammal. The vectors may be used for experimental research, for pre-clinical or clinical application. The vectors disclosed herein induce both cell-mediated and humoral immune responses and may be used in DNA vaccination.

Abstract: Adjuvant compositions comprising specific 5mer polypeptides in combination with antigen delivery systems and/or immunostimulatory molecules, such as immunostimulatory nucleic acid sequences, for enhancing the immune response of a coadministered antigen, are described.

Abstract: A modified CAG promoter which is capable of driving high levels of expression of sequences of interest inserted downstream therefrom is herein described.

Abstract: Porcine tissues were screened for the presence of Adeno-Associated Viruses (AAV). Several AAV sequences were isolated from various porcine tissues, and BLAST analysis confirmed high to low homology with known AAV sequences of different origin. Sequence analysis confirmed the isolation of at least three novel porcine AAV isolates which we named AAVpo1, -po2, and -po3. Novel AAVs derived from porcine tissues may significantly contribute to the generation of new preventive or curative clinical modalities acceptable for human use.

Abstract: Chimeric ebola envelope proteins and uses therefore are described. The chimeric envelope proteins are useful for packaging viral vectors and targeting these vectors in vivo, to lung cells following intratracheal delivery or for delivery of molecules, ex vivo, to macrophages and dendritic cells. In another aspect, also provided herein are immunogenic compositions which contain ebola envelope proteins and uses thereof.

Abstract: Recombinant transfer viruses, comprising an HIV minigene carrying a desired molecule, packaged in an envelope containing at least the binding domain of the ebola envelope protein, are described. Also described are methods of producing these transfer viruses and methods of using these viruses to deliver genes to selected target cells. These transfer viruses are particularly useful for delivery of molecules, in vivo, to lung cells following intracheal delivery or for delivery of molecules, ex vivo, to macrophages and dendritic cells.
