    Abstract: Provided herein are recombinant fusion polypeptides comprising one or more antigenic peptides (e.g., fused to a PEST-containing peptide) from cancer-associated proteins. The antigenic peptides can comprise one or more or all of an antigenic peptide comprising a recurrent cancer mutation, an antigenic peptide comprising a heteroclitic mutation, or an antigenic peptide fused to a ubiquitin protein. For example, provided herein are recombinant fusion polypeptides comprising two or more antigenic peptides (e.g., fused to a PEST-containing peptide), wherein each antigenic peptide comprises a recurrent cancer mutation, and wherein at least two of the antigenic peptides are fragments of the same cancer-associated protein. Also provided are nucleic acids encoding such fusion polypeptides, recombinant bacteria or Listeria strains comprising such fusion polypeptides or such nucleic acids, and cell banks comprising such recombinant bacteria or Listeria strains.

  • Patent number: 10624962
    Abstract: A detoxified recombinant E. coli heat-labile enterotoxin mutant, LTS61K, is employed as a carrier protein to conjugate polysaccharide. The LTS61K contains a mutated mature sub-unit A (LTA) that includes lysine at amino acid position 61 and a wild-type mature sub-unit B (LTB). Various types of bacterial capsular polysaccharide antigens were chemically conjugated with the LTS61K protein by a reductive amination reaction. The conjugated polysaccharide-LTS61K products were physically, chemically and biochemically identified as soluble form. Rabbits were immunized intramuscularly to determine the immunogenicity of conjugated vaccines by ELISA to detect anti-polysaccharide antigen IgG titers and serum bactericidal assay thereby determining the functional activity of the antibodies. Study results show that conjugated polysaccharide-LTS61K vaccines induce higher polysaccharide-specific IgG titers and greater bactericidal activity in sera than that of polysaccharide alone or polysaccharide mixed with LTS61K.

  • Patent number: 10598666
    Abstract: The invention uses ELISA or similar assays for analysing a meningococcal vaccine. The assay uses antibodies which bind to meningococcal proteins within the vaccine, and in particular monoclonal antibodies which are bactericidal for meningococcus and/or which recognise conformational epitopes within the meningococcal proteins. By performing the assay on a series of dilutions of a test vaccine, and by comparing the results with those obtained using a reference vaccine of known potency, it is possible to determine the relative potency of the test vaccine. This value can be used as a parameter for determining whether a manufactured batch of a vaccine is suitable for release to the public, or whether it has experienced a production failure and so should not be used.

  • Patent number: 10525119
    Abstract: Cold spot genes of S. pneumoniae are disclosed that encode surface proteins that are universally conserved among known strains and have exceptionally low incidence of allelic variation. Cold spot polypeptides encoded by the genes that are antigenic on the S. pneumoniae cells on which they are expressed are candidates for immunogenic compositions capable of eliciting antibodies able to react with all or nearly all strains of S. pneumoniae, thus providing an improvement over currently available S. pneumoniae vaccines that protect inoculated individuals against a maximum of about 23 of the 94 or so known serotypes of S. pneumonia.

  • Patent number: 10376572
    Abstract: The invention provides an immunogenic composition for preventing pneumococcal diseases, comprising PspA-MRX1, PspA-EF5668, PspA-EF3296 and PlyL460D, wherein the amount of each component is 10-100 ?g/ml; the immunogenic composition is prepared by adding to aluminum adjuvant the corresponding dosages of the four stock solutions PspA-mRX1, PspA-EF5668, PspA-EF3296 and PlyL460D, and mixing them homogeneously; the immunogenic composition can prevent infection and invasion by Streptococcus pneumonia, covering more than 95% of the strains in clinic. The immunogenic composition has a wide application in the prevention of pneumonia, and is suitable for large-scale production in industry for its simple preparation method, low production cost, and short production cycle.

  • Patent number: 10307527
    Abstract: Systems, compositions, methods and kits employ protein shells, such as ferritin or viral capsid shells, herein called nanobubbles, to enhance X-ray images of cells or body tissue under certain x-ray imaging methods. The nanobubbles have sub-micron size such as about 10 nm, about 40, 60, or 100 nm and may be functionalized for effective delivery to or uptake by a target tissue, in vivo or a cell culture. The nanobubbles are hollow, having a central core which may be empty or contain a fluid, such that the shells effectively form long-lived bubbles in the imaged environment, and are of low electron density and have different scattering properties than the surrounding tissue. X-ray imaging by spatial frequency heterodyne imaging enhances visualization or detection of tissue regions bearing the shells. The protein shells may be further treated to assure biocompatibility and/or to resist undesired interactions with non-targeted tissue, such as scavenging by the liver, or attack by the immune system.
