Abstract:
The present invention relates to Salmonella enterica comprising at least one pgl operon of Campylobacter jejuni or a functional derivative thereof and presenting at least one N-glycan of Campylobacter jejuni or N-glycan derivative thereof on its cell surface. In addition, it is directed to medical uses and pharmaceutical compositions thereof as well as methods for treating and/or preventing Campylobacter and optionally Salmonella infections and methods for producing these Salmonella strains.
Abstract:
Compositions that include Toll-like Receptor 5 agonists and at least a portion of at least one influenza antigen can be employed in methods that stimulate an immune response in a subject, in particular, a protective immune response in a subject. Compositions can be associated with particles and employed in the methods in relatively low doses to provide protective immunity to viral infection.
Abstract:
The present invention provides compositions comprising peptidyl inhibitors of CD40L-dependent signaling that are not derived from a natural binding partner of CD40L such as CD40, or from a native CD40-CD40L interface. More particularly, the peptidyl inhibitors of the present invention are derived from natural sources that do not express CD40-CD40L costimulatory pathways. The invention also provides synthetic derivatives and analogs of the peptidyl inhibitors having enhanced binding affinity for CD40L or enhanced inhibitory activity relative to their parent molecules.
Abstract:
The present invention is based on the discovery of novel species of the genus Helicobacter that are associated with gastroesophageal ulceration in pigs. In particular, a novel species, H. cerdo, has been used as a source of antigenic material for the development of vaccine for the treatment of the gastroesophageal disorders. Most advantageously, the novel Helicobacter and the porcine circoviruses associated with PMWS in pigs are useful for providing combination vaccines whereby immunogens derived from both types of pathogens may be codelivered to the tax get animal to stimulate the generation of protective antibodies and immunity. The invention, therefore, provides vaccines that are useful for the tratment of gastro esophageal ulceration and PMWS in porcines. The present invention includes, therefore, multivalent immunogenic compositions and vaccines, multivaccine kits, and combined immunization or vaccination methods which make it possible to use such combined immunization or vaccination programmes.
Abstract:
The present invention refers to pharmaceutical compositions comprising cholesteryl-α-glucosyltransferase from Helicobacter, inhibitors of cholesteryl-α-glucosyltransferase and the use thereof for the manufacture of a medicament for the prevention or/and treatment of Helicobacter infection or/and a Helicobacter -associated disease. Another subject is the screening method for novel inhibitors of cholesteryl-α-glucosyltransferase.
Abstract:
A novel Helicobacter pylori blood group antigen binding (BAB) adhesin protein was isolated and purified, whereby said protein or fractions thereof bind specifically to fucosylated blood group antigens. The protein sequence of said adhesin is disclosed in this application. Simultaneously the DNA sequences for two genes, babA and babB, producing highly similar proteins, are disclosed. Said adhesin and/or DNA is useful for diagnose and therapy and/or prophylaxis directed against H. pylori induced infections, e.g. gastritis and acid peptic disease, i.e. active vaccination. A new immunoglobulin composition, which exhibits specific activity to a Lewis antigen binding Helicobacter pylori adhesin, or preferably, monoclonal and/or polyclonal antibodies to said adhesin offer a new and more efficient method of treatment and/or prevention of gastrointestinal diseases, caused by Helicobacter pylori or other Helicobacter species, i.e. passive vaccination.
Abstract:
Recombinant or substantially pure preparations of H. pylori polypeptides are described. The nucleic acids encoding the polypeptides also are described. The H. pylori polypeptides are useful for diagnostics and vaccine compositions.
