摘要:
The present invention relates to compositions comprising Haemophilus influenzae Protein E and Pilin A. More particularly, the present application relates to fusion proteins and immunogenic compositions comprising Protein E and PilA, vaccines comprising such immunogenic compositions and therapeutic uses of the same.
摘要:
The present invention encompasses methods of producing influenza B viruses in cell culture. The influenza B viruses may have desirable characteristics, such as enhanced replication in eggs and may be used, for example, in vaccines and in methods of treatment to protect against influenza B virus infection.
摘要:
The present invention relates to the field of vaccines. More specifically the present invention relates to compositions and methods for enhancing immune responses induced by vaccines, including vaccines targeted at secondary infections and conditions associated with influenza infection.
摘要:
A method for producing an α-Gal-expressing virus having enhanced immune response to viruses, without requiring the use of any enzyme; an influenza virus vaccine having a high effect (antigenicity), which is produced using an α-Gal-expressing virus produced by the method; and others. Specifically disclosed are: a method for producing an α-galactose epitope (Galα1-3Galβ1-4GlcNAc -R: α-Gal hereinafter)-expressing virus, which comprises the steps of: (1) introducing an α1,3-galactosyltransferase gene in an expressible condition into a cell line that does not express α-Gal to obtain a cell line capable of expressing α-Gal; (2) inoculating a virus into the cell line capable of expressing α-Gal to obtain a cell line infected with a virus; and (3) culturing the cell line infected with the virus to obtain a virus expressing α-Gal from the culture medium.
摘要:
A therapeutic composition comprising a yeast expressing at least one heterologous intracellular antigen from an infectious pathogen or a disease and at least one heterologous extracellular antigen from the pathogen or the disease wherein the intracellular antigen is a different antigen than the extracellular antigen, use of the compositions in eliciting an antigen-specific cell-mediated and/or humoral immune response in an individual or in treating or preventing infection with the pathogen or for treating or preventing the disease, and a method to produce a therapeutic composition for eliciting a cell-mediated and/or a humoral immune response against an infectious pathogen or a disease.
摘要:
The present invention provides a human dose of an immunogenic composition comprising an antigen or antigenic preparation, in combination with an adjuvant which adjuvant comprises an immunologically active saponin fraction derived from the bark of Quillaja Saponaria Molina presented in the form of a liposome and a lipopolysaccharide wherein said saponin fraction and said lipopolysaccharide are both present in said human dose at a level of below 30µg. The present invention further provides an adjuvant composition in a human dose suitable volume comprising between 1 and 30 µg of a lipopolysaccharide and between 1 and 30 µg of an immunologically active saponin fraction presented in the form of a liposome.
摘要:
In one embodiment, the present invention provides for an edible mini-capsule form of live, non-persisting, recombinant Lactococcus lactis (L.lactis) vaccine against a pathogen such as the highly virulent influenza H5N1 strain. Enteric coated capsule of the present invention induced high levels of hemagglutinin-specific serum IgG and fecal IgA antibody production after oral administration in mice and chickens, and rendered complete protection against a lethal challenge of H5N1 virus in mice. The present invention thus demonstrates a broadly applicable platform technology for producing and administering edible vaccines against bacterial and viral infections.
