摘要:
The present invention is directed to novel polypeptides, polynucleotides and vaccines for use against Neisseria gonorrhoeae colonization or infection and/or Neisseria meningitidis colonization or infection. The vaccines contain an immunogenic amount of a neisserial protein.
摘要:
The invention provides BASB230 polypeptides and polynucleotides encoding BASB230 polypeptides and methods for producing such polypeptides by recombinant techniques. Also provided are diagnostic, prophylactic and therapeutic uses.
摘要:
A recombinant microorganism comprises an asporogenic Bacillus subtilis strain in which a gene encoding a protease enzyme has been downregulated or inactivated. In particular sigma factorspoIIAC is inactivated such that the strain is asporogenic. These strains are particularly useful as expression vehicles for proteins such as protective antigen (PA) of Bacillus anthracis.
摘要:
The present application discloses the preparation and use of attenuated tumor-targeted bacteria vectors for the delivery of one or more primary effector molecule(s) to the site of a solid tumor. The primary effector molecule(s) of the invention is used in the methods of the invention to treat a solid tumor cancer such as a carcinoma, melanoma, lymphoma, or sarcoma. The invention relates to the surprising discovery that effector molecules, which may be toxic when administered systemically to a host, can be delivered locally to tumors by attenuated tumor-targeted bacteria with reduced toxicity to the host. The application also discloses to the delivery of one or more optional effector molecule(s) (termed secondary effector molecules) which may be delivered by the attenuated tumor-targeted bacteria in conjunction with the primary effector molecule(s).
摘要:
A polypeptide conjugate contains a bacterial injectable effector protein, secreted by a modified pilus or nullneedle-likenull structure comprising a type m or type TV secretion apparatus, and a carrier that targets the conjugate to a target cell. The effector protein is used for a variety of purposes including treatment of neurodegenerative disease, intracellular infection and diseases associated with defects of secretion.
摘要:
The invention is directed generally to the structure of prenyltransferases, particularly undecaprenyl pyrophosphate synthase, an enzyme important in bacterial cell wall synthesis. The invention relates to the crystal structure of undecaprenyl pyrophosphate synthase from Streptococcus pneumoniae and its interaction with cofactors and ligands. The invention also relates to the structure of ligand and cofactor binding sites of undecaprenyl pyrophosphate synthase.
摘要:
Disclosed herein are antigens that stimulate protective antibodies against enterotoxigenic Escherichia coli. Also disclosed herein are proteins encoded by cssA and cssB genes as well as constructs containing the genes and methods of using thereof.
摘要:
A gene delivery system is composed of a yeast hybrid delivery system vector. Two gene-expressing units form the yeast hybrid vaccine delivery system by gene type mating. One unit is engineered to constitutively express a co-stimulator and another can be engineered to express single, fusion or multiple antigens derived from disease causing pathogen. This yeast hybrid vaccine easy delivery system vector is designed to develop novel vaccines. The candidate vaccines include AIDs, cancer, Hepatitis C, Parainfluenza, malaria, autoimmunity and other infectious diseases.
摘要:
A composition comprising: (a) one to three bioactive agents; and (b) a modified liquid vehicle; wherein immediately after manufacture of the composition, said composition can be administered to a host such that the one to three bioactive agents is released to the host on a sustained basis is provided.
