摘要:
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.

The present invention discloses methods and materials for delivering a cargo compound into a cancer cell. Delivery of the cargo compound is accomplished by the use of protein transduction domains derived from cupredoxins. The cargo compound may be a nucleic acid and specifically a DNA, RNA or anti-sense. The invention further discloses methods for treating cancer and diagnosing cancer.

摘要:
Methods and compositions are provided for the enhanced production of bacterial toxins in large-scale cultures. Specifically, methods and compositions for reducing bacterial toxin expression inhibitors are providing including, but not limited to, addition of toxin expression inhibitor binding compounds, culture media having reduced concentrations of toxin inhibitor metabolic precursors and genetically modified toxogenic bacteria lacking enzymes required to metabolize the toxin inhibitor metabolic precursors.
摘要:
The present invention discloses the structure and sequence of aroQ from Bordetella pertussis, which are useful inter alia for the production of the genetically modified attenuated Bordetella strains of the present invention and for detecting and isolating variant aroQ genes and expression products. The present invention also discloses attenuated Bordetella strains of pathogenic origin, and more particularly genetically modified Bordetella strains, which have been attenuated by disruption or inactivation of the aroQ gene. The genetically modified Bordetella strain of the present invention has a reduced capacity to propagate in a mammalian host, but remains viable in the host for a period of time sufficient to induce a protective immune response against the natural pathogenic Bordetella counterpart. The present invention is also directed to the use of such genetically modified Bordetella strains in immunopotentiating compositions for treating and/or preventing inter alia Bordetella infections, and particularly pathogenic infections, caused by Bordetella.
摘要:
A first embodiment is a specific plasmid vector, pDIP/PyCSP.1, into which nucleotides encoding the targets of specific immune responses are inserted. These targets include, but are not limited to proteins and peptides. These plasmid constructs are incorporated in a composition comprising a suitable and acceptable art recognized pharmaceutical reagent that is benign (non-reactive with) to the plasmid construct. The plasmid construct provides protective immune responses to the disease associated with the selected targets. A second embodiment is a construct having, at a minimum, the nucleotide sequences encoding one or more Plasmodium species proteins in a pharmaceutically acceptable vector. a third embodiment is a method of controlling malaria in mammals comprising injecting a polynucleotide delivery vector into a mammal.
摘要:
Nucleic acid and protein compositions are provided from B. pertussis which may find use in diagnosis, prevention and therapy of whooping cough. Particularly, an open reading frame encoding filamentous hemagglutinin precursors provided, with the intact protein for the filamentous hemagglutinin portion thereof, can be expressed in a wide variety of hosts, for use in the production of antibodies, for immunodiagnosis or therapy, or as vaccines for prophylactic purposes.
摘要:
A host cell which is provided with a S-layer comprising a fusion polypeptide consisting essentially of:(a) at least sufficient of a S-layer protein for a S-layer composed thereof to assemble, and(b) a heterologous polypeptide which is fused to either the carboxy terminus of (a) or the amino terminus of (a) and which is thereby presented on the outer surface of the said cell; can be used as a vaccine, for screening for proteins and antigens and as a support for immobilizing an enzyme, peptide or antigen. A process of transforming B. Sphaericus cells comprising electroporation is also provided.
摘要:
A protein expression levels from Bordetella strains, particularly Bordetella pertussis, are altered by genetic modification to a natural Bordetella strain whereby one or more of the natural genes, particularly including the TOX, FHA, CYA and PRN genes, is deleted from the genome of the natural strain and one or more of the natural genes or a genetic mutation thereof, particularly a genetically-detoxified TOX* gene, or a hybrid gene, is inserted into the genome of the natural strain to provide at least two copies of one or more of the natural genes or genetic mutation thereof or hybrid gene, singly or in tandem. The altered genotype Bordetella strain is useful in producing whole-cell or defined component vaccines against Bordetella, particularly whooping cough, which may be employed in combination with other vaccines.
