Abstract: A highly efficient method for generating human antibodies in particular which are specific to be RSV fusion protein which combines in vitro priming of human spleen cells and antigen boosting in SCID mice is taught. This method provides for very high human antibody titers which are predominantly of the IgG isotype which contain antibodies of high specificity and affinity to desired antigens. This method is well suited for generating human monoclonal antibodies for therapeutic and diagnostic applications as well as for rescue of human cells for generation of combinational human antibody gene libraries. Two human monoclonal antibodies, RF-1 and RF-2 which each possess an affinity for RSV F-protein≦2×10−9 Molar are taught as well as their corresponding amino acid and DNA sequences. These antibodies are to be used therapeutically and prophylactically for treating or preventing RSV infection, as well as for diagnosis of RSV in analytes.
Abstract: Methods for obtaining a protein by culture of hybridoma cells, wherein said protein is an immunoglobulin, are disclosed. The methods involve culturing animal hybridoma cells in continuous presence of an alkanoic acid or salt thereof, which enhances protein production, wherein said alkanoic acid or salt thereof is present at 2 concentration range of 0.1 mM to 200 mM.
Abstract: Recombinant parainfluenza virus (PIV) are provided in which expression of the C, D and/or V translational open reading frame(s) (ORFs) is reduced or ablated to yield novel PIV vaccine candidates. Expression of the C, D and/or V ORF(s) is reduced or ablated by modifying a recombinant PIV genome or antigenome, for example by introduction of a stop codon, by a mutation in an RNA editing site, by a mutation that alters the amino acid specified by an initiation codon, or by a frame shift mutation in the targeted ORF(s). Alternatively, the C, D and/or V ORF(s) is deleted in whole or in part to render the protein(s) encoded thereby partially or entirely non-functional or to disrupt protein expression altogether. C, D and/or V ORF(s) deletion and knock out mutants possess highly desirable phenotypic characteristics for vaccine development. These deletion and knock out mutations changes specify one or more desired phenotypic changes in the resulting virus or subviral particle.

Abstract: Infectious bursal disease viruses were isolated from broiler chickens experiencing proventriculitis in, for example, Oklahoma, Texas, West Virginia, and California. Chicken virus isolates Texas RB 3, Texas RB 4, HBS, F57-7, W/L 39, GAR 1, and the like have been isolated. These viruses are some of the major causes of this condition and can be utilized as or in a vaccine to prevent the disease condition. The viruses are a significant finding in the search for a causative agent for proventriculitis in broiler chickens and as such may be utilized in the development of a vaccine or vaccines. The viruses can be attenuated to be used as a modified live vaccine or utilized in an inactivated form in a killed vaccine.
Abstract: Methods of reducing pre-existing humoral immunity to a viral immunogenic therapeutic agent such as adenovirus, using immunoapheresis are disclosed. Antibodies specific for the viral immunogenic therapeutic agent are selectively removed from the blood of an individual prior to administration of the viral immunogenic therapeutic agent by reaction extracorporeally with an immunosorbent which specifically binds the antibody. After the antibody is selectively removed from the blood, the blood is reinfused into the patient and the viral immunogenic therapeutic agent is administered. The invention also provides kits and compositions for selective removal of anti-viral antibody.

Abstract: The invention allows, for the first time, to (almost) perfectly detect the various phases of a BDV infection in all species by combining a newly discovered test parameter, the circulating immune complexes (CICs) in the blood plasma, with already known parameters, antigen (AG) in white blood cells and antibodies (AK) in the plasma. All three parameters can be determined from a single blood sample. The detection of BDV-specific CICs described for the first time by the invention as the only infection markers with long-time persistence allows both the detection of healthy carriers (latent infections) and the evaluation of the development of the infection and of therapy results in the case of diseased individuals.
Abstract: A method for preventing or reducing bacterial contamination of a viral vaccine is disclosed. The method comprises adding an effective preserving amount of a polybiguanide-containing preservative composition to a solution containing vaccine virus or virus antigen. The method is particularly useful in preventing or reducing bacterial contamination of process solutions involved in the manufacture of influenza vaccines.
Abstract: A composition which elicits antibodies to multiple known variants of Tat protein of HIV-1 of both the B and non-B clades contains the peptide R1-Asp-Pro-Asn-Leu-Asp-Pro-Trp-Asn-R2 SEQ ID NO: 23, and preferably an additional at least two variants of a peptide or polypeptide of the formula: R1-Asp-Pro-Y7-Leu-Glu-Pro-Trp-Z12-R2 SEQ ID NO: 8. In this composition, at least one of the two variants contains Arg at Y7 and Lys at Z12, and in at least a second of the two variants Y7 is Asn and Z12 is Asn. Vaccinal and pharmaceutical compositions can contain one or more such peptides associated with carrier proteins, associated in multiple antigenic peptides, or as part of recombinant proteins. Diagnostic compositions and uses are described for assessing the immune status of vaccinated patients.

Abstract: Methods are disclosed whereby protease activity is directly linked to delivery of a transferable label to a target cell which expresses a protease, via fusion of viral display packages comprising the transferable label with the target cell. The methods can be used, inter alia, to identify proteases, including previously undiscovered proteases or variants of known proteases which may have altered substrate specificity.

Abstract: The present invention relates to five synthetic peptides of pre-M/M protein of Dengue-2 virus, corresponding to amino acid sequences 3-31, 45-67, 57-92, 69-93 and 103-124. The anti-peptide immune response was evaluated in mice. Recombinant fusion proteins were also obtained, including regions of pre-M/M protein. The presence of B cell epitopes in both mice and humans was demonstrated in the pre-M/M protein peptides. Peptides 3-31 and 103-124 elicited neutralizing antibodies against the four serotypes of Dengue virus. Virus-specific proliferative responses were demonstrated in mice immunized with non-conjugated peptides 3-31 and 57-92. Mice immunized with conjugated peptides 3-31, 57-92, and 69-93 were protected when they were challenged with Dengue-2 virus. Thus, the presence of sequential epitopes in Pre-M/M protein of Dengue-2 virus was demonstrated, as well as their relevance in the immune response against this flavivirus.
