  • Patent number: 9150621
    Abstract: The present invention relates to the use of mutant glycoproteins from pathogenic bacteria lacking one or more phosphorylcholine and/or glycosylation post-translational modifications as immunogens. These post-translational modifications act as masking structures that elicit an immune response which does not confer protection on an infected individual. The removal or modification of these masking structures alters the protein such that it elicits a stronger immune response to the protein and/or the bacterial pathogen. Particular examples are pilin proteins and nitrite reductase glycoproteins of Neisseria bacteria.

    Abstract: The present invention relates to immunogenic compositions and vaccines for the treatment and prevention of Neisserial disease. Immunogenic compositions of the invention comprise the Hsf (also called Msf) and Opc neisserial antigens. These antigens have been found to be the two mechanisms by which Neisseria meningitidis binds host vitronectin (in order to promote adhesion and/or to evade host complement mediated killing). Vaccines comprising both antigens can thus advantageously result in an immune response which is better able to kill neisserial strains and otherwise prevent vitronectin-related neisserial complement mediated killing resistance and/or neisserial adhesion events required for pathogenesis.

The glycosyltransferases of the invention are particularly suited to the synthesis of the oligosaccharides Gal?1?4GlcNAc?1?3Gal?1?4Glc (a mimic of lacto-N-neotetraose), GalNAc?1?3Gal?1?4GlcNAc?1?3Gal?1?4Glc?1?4 (a mimic ganglioside), and Gal?1?4Gal?1?4Glc?1?4Hep?R (a mimic of the saccharide portion of globo-glycolipids).

  • Patent number: 8221770
    Abstract: The present invention relates to the field of neisserial vaccine compositions, their manufacture, and the use of such compositions in medicine. More particularly it relates to processes of making novel engineered meningococcal strains which are more suitable for the production of neisserial, in particular meningococcal, outer-membrane vesicle (or bleb) vaccines. Advantageous processes and vaccine products are also described based on the use of novel LOS subunit or meningococcal outer-membrane vesicle (or bleb) vaccines which have been rendered safer and/or more effective for use in human subjects. In particular combinations of gene downregulations are described such as PorA and OpA, PorA and OpC, OpA and OpC, and PorA and OpA and OpC. Alternatively, or in addition, lgtB? is shown to be an optimal mutation for effectively and safely using L3 and/or L2 LOS in Neisseria vaccine compositions.

  • Patent number: 8188251
    Abstract: The present invention discloses methods and materials for delivering a cargo compound into a brain cancer cell and/or across the blood-brain barrier. Delivery of the cargo compound is accomplished by the use of protein transport peptides derived from Neisseria outer membrane proteins, such as Laz. The invention also provides synthetic transit peptides comprised of the pentapeptide AAEAP (SEQ ID NO: 25). The invention further discloses methods for treating cancer, and specifically brain cancer, as well as other brain-related conditions. Further, the invention provides methods of imaging and diagnosing cancer, particularly brain cancer.

  • Patent number: 8173140
    Abstract: Methods for making and using therapeutic formulations of Proteosome-based immunoactive compositions are provided. The immunogenic compositions, which include Proteosomes and liposaccharides, may be used to elicit or enhance a nonspecific innate immune response to, for example, treat or prevent infectious disease. In addition, after activating the innate immune system, immunogenic compositions further containing an antigen may be used to elicit a specific adaptive immune response. Furthermore, provided are compositions capable of altering hyperreactive responses or inflammatory immune responses, such as allergic reactions. Such compositions may be used as a prophylactic, or in various clinical settings to treat or prevent infectious disease (such as parasite, fungal, bacterial or viral infections), or to alter inappropriate inflammatory immune responses (such as allergic reactions or asthma).

  • Patent number: 8163295
    Abstract: The present invention discloses a Gram negative bacterium in which the expression of a protein involved in LPS transport to the outer membrane is functionally down-regulated such that the level of LPS in the outer membrane is decreased compared to a wild-type Gram negative bacterium. Down regulation of Imp and MsbA proteins can result in such a bacterium. Outer membrane vesicle preparations derived from the Gram negative bacterium of the invention can be used in vaccines to provide protection against bacterial infection.

  • Patent number: 8163296
    Abstract: GPC (gel permeation chromatography) and size exclusion chromatography with detection by multi-angle light scattering photometry (SEC-MALS) can be used to accurately measure molecular size and molar mass, respectively, of saccharide conjugates. The invention provides (a) a process for measuring the molecular size of a conjugated saccharide antigen within a sample, comprising a step of analyzing the sample by GPC, and (b) a process for measuring the molar mass of a conjugated saccharide antigen within a sample, comprising a step of analysing the sample by SEC-MALS.

  • Publication number: 20120064119
    Abstract: The present invention relates to immunogenic compositions and vaccines for the treatment and prevention of Neisserial disease. Immunogenic compositions of the invention contain combinations of antigens selected from at least two different classes of antigens including adhesins, autotransporter proteins, toxins, iron acquisitions proteins and membrane-associated protein (preferably integral outer membrane protein)s. Such combinations of antigens are able to target the immune response against different aspects of the neisserial life cycle, resulting in a more effective immune response.
