Abstract: Disclosed herein is a novel recombinant virus vector derived from the attenuated vaccinia virus strain KVAC103. The recombinant virus vector is obtained by inserting an exogenous gene into the KVAC103 and may be used as a safe vaccine delivery vehicle in mammals. Particularly, recombinant viruses obtained by rescuing some of the genes deleted from the parent virus have an enhanced ability to proliferate in cells being cultured, and thus are easily produced. In addition, the recombinant viruses express an increased level of an exogenous antigen, and thus has enhanced immunogenic efficacy. Such recombinant virus vectors may be used in vaccines for preventing diseases, therapeutic vaccines, and molecular biological studies.

A vector including such a nucleic acid, an immunogenic or vaccinal composition including the vector or the nucleic acid, as well as their use for treating and/or preventing an infection by a retrovirus or a disease induced by a pathogenic agent are also described.

Abstract: The present invention is directed to antigen binding proteins including, but not limited to, monoclonal antibodies and antigen binding fragments thereof, that specifically bind to and preferably neutralize human cytomegalovirus (CMV).

Abstract: The present invention relates to a method for the in vitro prediction of the probability of a patient developing severe dengue, based on a blood sample, which involves: a) determining the quantity of at least one marker, and b) comparing the quantity with a reference quantity obtained from a group of individuals who have been diagnosed with non-severe dengue, and if the quantity determined in step a) is greater than the reference quantity established in step b), predicting that the patient will develop severe dengue, and also to the use of predictive marker(s) and to a kit to predict the development of severe dengue.

Abstract: This disclosure relates to recombinant bacteria, e.g. L. lactis, expressing heterologous pili containing human immunodeficiency virus (HIV) antigens. In certain embodiments, the recombinant bacteria are administered in combination with other HIV antigens, nucleic acids encoding HIV antigens, recombinant virus encoding HIV antigens, anti-viral agents and/or adjuvants in an effective amount to elicit a mucosal immune response against HIV.

Abstract: The invention relates to a method for preparing double-layered virus-like particles of rotavirus in vitro. The method comprises the following steps: purifying rotavirus VP6 proteins from a lysis supernatant, and in vitro assembling double-layered virus-like particles consisting of VP2 proteins and VP6 proteins, wherein the proteins and the virus-like particles can be used for preventing or reducing the clinical symptoms caused by rotavirus infection.

Abstract: Disclosed herein are mosaic HIV envelope (Env) polypeptides that can elicit an immune response to HIV (such as cytotoxic T cell (CTL), helper T cell, and/or humoral responses). Also disclosed are sets of the disclosed mosaic Env polypeptides, which include two or more (for example, three) of the polypeptides. Also disclosed herein are methods for treating or inhibiting HIV in a subject including administering one or more of the disclosed immunogenic polypeptides or compositions to a subject infected with HIV or at risk of HIV infection. In some embodiments, the methods include inducing an immune response to HIV in a subject comprising administering to the subject at least one (such as two, three, or more) of the immunogenic polypeptides or at least one (such as two, three, or more) nucleic acids encoding at least one of the immunogenic polypeptides disclosed herein.

Abstract: Provided are methods for identifying whether a compound inhibits entry of a virus into a cell. The method may include obtaining nucleic acid encoding a viral envelope protein from a patient infected by the virus and co-transfecting it into a first cell along with a viral expression vector which lacks a nucleic acid encoding the envelope protein. The method may further include contacting the viral particles produced by the first cell with a second cell to which the virus binds in the absence and presence of the compound and measuring the amount of signal produced by the second cell.

Abstract: The present invention relates to the field of detection of viruses, and in particular to detection of viruses using a liquid crystal assay format. In the present invention, virus binding in a detection region is identified by changes in liquid crystal orientation caused by virus binding independent orientation caused by any topography associated with the detection region.

Abstract: The invention relates to a dengue virus tetravalent vaccine containing a common 30 nucleotide deletion (?30) in the 3?-untranslated region of the genome of dengue virus serotypes 1, 2, 3, and 4, or antigenic chimeric dengue viruses of serotypes 1, 2, 3, and 4.

Abstract: The invention provides broadly neutralizing antibodies directed to epitopes of Human Immunodeficiency Virus, or HIV. The invention further provides compositions containing HIV antibodies used for prophylaxis, and methods for diagnosis and treatment of HIV infection.

Abstract: The subject of the invention is a method for purifying the rabies virus, comprising a single ion-exchange chromatography step, said step being cation exchange chromatography according to which: a) the supernatant of a culture of cells infected with this virus is brought into contact with a cation exchange chromatography support comprising a polymethacrylate matrix onto which sulfoisobutyl groups have been grafted such that the rabies virus binds to this support, and; b) the virus is eluted from its support.
