摘要:
This invention relates to conjugates of the Vi polysaccharide of S. typhi with the carrier Pseudomonas aeruginosa recombinant exoprotein A (rEPA), and compositions thereof, and to methods of using of these conjugates and/or compositions thereof for eliciting an immunogenic response in humans, including responses which provide protection against, or reduce the severity of, S. typhi bacterial infections. The conjugates, and compositions thereof, are useful as vaccines to induce serum antibodies against S. typhi and are useful to prevent and/or treat illnesses caused by S. typhi.
摘要:
The invention relates to improved methods of producing and recovering B. anthracis protective antigen (PA), especially modified PA which is protease resistant, and to methods of using of these PAs or nucleic acids encoding these PAs for eliciting an immunogenic response in humans, including responses which provide protection against, or reduce the severity of, B. anthracis bacterial infections and which are useful to prevent and/or treat illnesses caused by B. anthracis, such as inhalation anthrax, cutaneous anthrax and gastrointestinal anthrax.
摘要:
Disclosed are immunogenic conjugates having the general formula: M2e-Cys-S—CH2—C(O)—NH—CH2—CH2-C(O—)NH-Lys-Pr, were M2e is the influenza M2 ectodomain (M2e) peptide; Cys is a cysteine amino acid residue present in the M2e peptide; S the sulfur present in the cysteine amino acid residue; CH2-CO—NH—CH2-CH2-CO the linking group; NH the amine group present in a lysine residue of the carrier; Lys is a lysine amino acid residue and Pr the carrier protein. Also disclosed are isolated immunogens that include an immunogenic fragment of an influenza HA protein including the polybasic cleavage site, wherein the immunogenic fragment of the influenza HA protein has been modified to remove an N-terminal leader amino acid sequence and a C-terminal transmembrane domain. Also disclosed are methods producing an influenza vaccine specific for an identified influenza strain.
摘要:
Unique compounds that can be used for inducing an immune response to Borrelia burgdorferi in a subject by administering a therapeutically effective amount of the glycolipid to the subject. Such administration is particularly useful for preventing or treating Lyme disease in a subject. The compounds(s), and therapeutically acceptable salts thereof, may be formulated into pharmaceutical or immunogenic compositions.
摘要:
Disclosed are immunogenic conjugates which elicit an immune response to Plasmodium proteins. In particular examples, the Plasmodium proteins include sexual stage surface proteins, circumsporozoite protein (CSP), or immunogenic portions of CSP. Also provided herein are immunogenic compositions including one or more of the disclosed immunogenic conjugates and a pharmaceutically acceptable carrier. Further provided is a method of eliciting an immune response to Plasmodium in a subject, comprising administering to the subject an immunogenic composition disclosed herein.
摘要:
The invention relates to improved methods of producing and recovering sporulation-deficient B. anthracis mutant stains, and for producing and recovering recombinant B. anthracis protective antigen (PA), especially modified PA which is protease resistant, and to methods of using of these PAs or nucleic acids encoding these PAs for eliciting an immunogenic response in humans, including responses which provide protection against, or reduce the severity of, B. anthracis bacterial infections and which are useful to prevent and/or treat illnesses caused by B. anthracis, such as inhalation anthrax, cutaneous anthrax and gastrointestinal anthrax.

摘要:
Provided are immunogenic compositions and methods for eliciting an immune response against B. anthracis and other bacteria that contain 3-methyl-3-hydroxybutyrate- or 3-hydroxybutyrate-substituted saccharides. Conjugates of 3-methyl-3-hydroxybutyrate- or 3-hydroxybutyrate-substituted saccharides elicit an effective immune response against B. anthracis spores in mammalian hosts to which the conjugates are administered.
