Abstract:
The invention relates to a recombinant protein comprising one or several polypeptides bearing one or several epitopes of one or several HPV antigens, said polypeptides being inserted in the same or different permissive sites of an adenylate cyclase (CyaA) protein or of a fragment thereof, wherein said CyaA fragment retains the property of said adenylate cyclase protein to target Antigen Presenting Cells. It also concerns polynucleotides encoding the same. The recombinant protein or the polynucleotide can be used for the design of therapeutic means against HPV infection or against its malignant effects.
Abstract:
The present invention generally provides compositions methods and composition relating to the diagnosis and/or treatment of cancers having a cell surface de-N-acetylated sialic acid antigen, e.g., an at least partially de-N-acetylated ganglioside and/or a de-N-acetylated sialic acid-modified cell surface protein.
Abstract:
The present application discloses an immunogenic composition comprising a Hib saccharide conjugate, at least one additional bacterial, for example N. meningitidis, saccharide conjugate(s), and a further antigen selected from the group consisting of whole cell pertussis and hepatitis B surface antigen, wherein the saccharide dose of the Hib saccharide conjugate is less than 5 μg.
Abstract:
Precipitated bacterial capsular polysaccharides can be efficiently re-solubilised using alcohols as solvents. The invention provides a process for purifying a bacterial capsular polysaccharide, comprising the steps of (a) precipitation of said polysaccharide, followed by (b) solubilisation of the precipitated polysaccharide using ethanol. CTAB can be used for step (a). The material obtained, preferably following hydrolysis and sizing, can be conjugated to a carrier protein and formulated as a vaccine. Also, in vaccines comprising saccharides from both serogroups A and C, the invention provides that the ratio (w/w) of MenA saccharide:MenC saccharide is >1.
Abstract:
The invention provides mutants of GAS57 (Spy0416) which are unable to cleave IL-8 and similar substrates but which still maintain the ability to induce protection against S. pyogenes. The invention also provides antibodies which specifically bind to GAS57 and which inhibit its ability to cleave IL-8 and similar substrates. The mutants are useful, inter alia, in vaccine compositions to induce protection against S. pyogenes. The antibodies are useful, e.g., as therapeutics for treating S. pyogenes infections.
Abstract:
The invention relates to methods of producing, and compositions comprising, an isolated alpha (2→8) or (2→9) oligosialic acid derivative bearing a non-reducing end enriched for one or more de-N-acetyl residues and resistant to degradation by exoneuraminidase. A representative production method involves: (i) treating an alpha (2→8) or (2→9) oligosialic acid precursor having a reducing end and a non-reducing end with sodium borohydride under conditions for de-N-acetylating the non-reducing end; and (ii) isolating alpha (2→8) or (2→9) oligosialic acid derivative having one or more de-N-acetylated residues and a non-reducing end that is resistant to degradation by exoneuraminidase. Isolated alpha (2→8) or (2→9) oligosialic acid derivatives that comprise a non-reducing end de-N-acetyl residue are provided, as well as antibodies specific for the derivatives, compositions comprising the derivatives, kits, and methods of use including protection against and detection of E. coli K1 and N. meningitidis bacterial infection, and in diagnosing and treating cancer.

Abstract:
The present invention relates to an immunogenic and a non-toxic glycoconjugate comprising Bordetella pertussis LOS-derived oligosaccharide and pertussis toxin, a method of preparing such glycoconjugate, the pharmaceutical composition, a vaccine composition containing such glycoconjugate, and an application of the glycoconjugate. The glycoconjugate is prepared as a vaccine component for protection against infections caused by Bordetella pertussis.
Abstract:
The present invention relates to a process for stabilizing an adjuvant containing vaccine composition, an adjuvanted vaccine composition in dry form and in particular a process for stabilizing an influenza vaccine composition, particularly an adjuvanted influenza vaccine composition in dry form.
Abstract:
The invention is in the field of outer membrane vesicles (OMV) and their uses. More particularly the present invention provides OMV obtained from a bacterium being an ompA mutant and/or a mutant in one or more components of the TolPal complex and presenting a heterologous antigen on its surface. The heterologous antigen is selected from the group consisting of Chlamydia trachomatis CT823, CT681, CT372, CT443, CT043, CT733, CT279, CT601 and CT153 for the treatment, prevention or diagnosis of Chlamydia infection.
Abstract:
The invention describes a method of purifying polysaccharide protein conjugates using mixed mode chromatography. The method involves contacting a crude polysaccharide protein conjugate with a mixed mode resin comprising an inert porous shell and an activated core under conditions of low conductivity that allow binding of the contaminants and collecting the unbound polysaccharide protein conjugate in a flowthrough.
