摘要:
The present invention discloses the detection of an important 12K-Da protein having cross-reactivity amongst different prevalent allergenic grasses and fungi can be useful for detection of respiratory allergies. Conventionally, the whole extracts that are used for diagnosis are unable to specifically detect the causative agents. In addition, they are also responsible for additional non-specific sensitivities in patients to other components present in the extract. If a single cross-reactive protein is available, it can replace large number of extracts used for detection of raised IgE levels in allergy by ELISA, immunoblotting and the likes. Further, number of pricks would be reduced and this would benefit both patient and clinicians. It is further realized that production of such a protein by recombinant methods can lead to its availability in pure form and bulk amounts required for routine diagnosis.
摘要:
The present invention provides a vaccine for inducing an immune response in mammal to a specific antigen, where the vaccine comprises a unit dose of a binary toxin protective antigen and the antigen, which is bound to a binary toxin protective antigen binding protein. In one embodiment the vaccine is comprised of an anthrax protective antigen and the antigen bound to anthrax protective antigen binding protein. The present invention also provides a method of immunizing a mammal against an antigen using the vaccine, and a method of inducing antigen-presenting mammalian cells to present specific antigens via the MHC class I processing pathway.
摘要:
The present invention provides a nucleic acid encoding a fusion protein, comprising a nucleotide sequence encoding the protective antigen (PA) binding domain of the native lethal factor (LF) protein and a nucleotide sequence encoding an activity inducing domain of a second protein. Also provided is a nucleic acid encoding a fusion protein, comprising a nucleotide sequence encoding the translocation domain and LF binding domain of the native PA protein and a nucleotide sequence encoding a ligand domain which specifically binds a cellular target. Proteins encoded by the nucleic acid of the invention, vectors comprising the nucleic acids and hosts capable of expressing the protein encoded by the nucleic acids are also provided. A composition comprising the PA binding domain of the native LF protein chemically attached to a non-LF activity inducing moiety is further provided. A method for delivering an activity to a cell is provided. The steps of the method include administering to the cell a protein comprising the translocation domain and the LF binding domain of the native PA protein and a ligand domain, and administering to the cell a product comprising the PA binding domain of the native LF protein and a non-LF activity inducing moiety, whereby the product administered is internalized into the cell and performs the activity within the cell.

A composition comprising the PA binding domain of the native LF protein chemically attached to a non-LF activity inducing moiety is further provided. A method for delivering an activity to a cell is provided. The steps of the method include a) administering to the cell a protein comprising the translocation domain and the LF binding domain of the native PA protein and a ligand domain, and b) administering to the cell a product comprising the PA binding domain of the native LF protein and a non-LF activity inducing moiety, whereby the product administered in step b) is internalized into the cell and performs the activity within the cell. The invention also provides proteins including an anthrax protective antigen which has been mutated to replace the trypsin cleavage site with residues recognized specifically by the HIV-1 protease.
摘要:
The present invention provides a vaccine for inducing an immune response in mammal to a specific antigen, where the vaccine comprises a unit dose of a binary, cytotoxic T lymphocyte vaccine comprising an anthrax protective antigen and a full length protein antigen bound to a nontoxic anthrax protective antigen binding protein comprising at least about the first 250 amino acid residues of the lethal factor of Bacillus anthracis and less than all of the amino acid residues of the lethal factor. The present invention also provides a method of immunizing a mammal against an antigen using the vaccine, and a method of inducing antigen-presenting mammalian cells to present specific antigens via the MHC class I processing pathway.
