The present invention relates to chimeric particles comprising single stranded RNA (ssRNA), double stranded RNA (dsRNA) and at least one cationic agent, a pharmaceutical composition containing said particles and to a method of producing the same. The particles of the present invention are particularly useful as an immunostimulating medicament with a superlative pattern of immunostimulation.

The invention concerns nucleotides vaccines encoding influenza proteins with few or no glycosylation sites. Since these first introductions of pandemic influenzas the viruses have drifted, accumulating mutations at antigenic sites, but also the N-glycosylation pattern has changed during the drifted years, accumulating N-linked glycosylation sequons that help mask the antigenic sites for recognition by the host immune system. These “naked” initial haemagglutinins induce a broad cross reactivity against widely drifted influenza subtypes. The origin of the DNA or RNA can be both pandemic influenza strains, which codes for proteins which have a naturally low content of glycosylation sites and/or DNA or RNA from non-pandemic influenza strains where the nucleotides have been mutated or changed so it encodes for proteins with less or no glycosylation sites. The invention also discloses DNA or RNA encoding the haemagglutinin (HA) from pandemic influenza A, e.g. the 1918 H1N1 and/or the 1957 H2N2 and/or the 1968 H3N2 influenza A virus, optionally with the Neuraminidase (NA) and/or matrix protein (M) and/or the nucleoprotein (NP) from these pandemic influenza virus included, mixed together with DNA or RNA from non-pandemic influenza A as a vaccine against present day and future influenza A viruses.

Provided herein are antibodies that specifically bind to GITR. Also described are related polynucleotides capable of encoding the provided GITR-specific antibodies or antigen-binding fragments, cells expressing the provided antibodies or antigen-binding fragments, as well as associated vectors and detectably labeled antibodies or antigen-binding fragments. In addition, methods of using the provided antibodies are described. For example, the provided antibodies may be used to enhance an immune response in a subject against cancer.

Compounds disclosed herein are effective against Ralstonia pickettii for treating or preventing insulin resistance, obesity or type II diabetes of a subject, and include an antibiotic effective against Ralstonia pickettii, an immunogenic compound producing a protective immune response, or an antibody which specifically binds to Ralstonia pickettii or a fragment thereof. In vitro methods for diagnosis or prediction of insulin resistance, obesity or type II diabetes include determining the presence of Ralstonia pickettii or of an antibody which specifically binds to Ralstonia pickettii in a test sample. An antibody binding specifically to an antigen of Ralstonia pickettii, a Ralstonia pickettii cell, or a nucleic acid hybridizing under stringent conditions to a nucleic acid from Ralstonia pickettii is disclosed. A kit including said antibody, the nucleic acid, and optionally a Ralstonia pickettii bacteria or a nucleic acid or protein thereof, a further reagent or a conventional kit component, is also disclosed.

The invention provides therapeutic compositions that present an artificial repertoire of mammalian pattern recognition receptor (PRR) agonists, so that the pattern of PRR agonists recapitulates a distinct portion of a PRR agonist signature of a mammalian pathogen. The artificial repertoire of PRR agonists may be formulated together in a therapeutic vehicle for combined presentation to an innate immune cell resident in a target tissue in a mammalian host, and the vehicle adapted to deliver the PRR agonists to the target tissue, so as to modulate an immune response.

The present invention provides pharmaceutical compositions capable of inducing an immune response in a subject, comprising an effective amount of a viral immunogen and an adjuvant, wherein the adjuvant comprises a lipid A mimetic. Methods for inducing an immune response are also provided.

Provided herein is a method for preventing a person from an infection by a Coronaviridae virus with a poliomyelitis vaccine. Also provided herein is a method of inducing a protective immune response against a Coronaviridae virus with a poliomyelitis vaccine.

Disclosed herein are compositions and methods related to mutant viruses, and in particular, mutant influenza viruses. The mutant viruses disclosed herein include a mutant M2 sequence, and are useful in immunogenic compositions, e.g., as vaccines. Also disclosed herein are methods, compositions and cells for propagating the viral mutants, and methods, devices and compositions related to vaccination.

An object of the present invention is to provide immunogenic compositions for protection against S. pneumoniae, in particular against S. pneumoniae serogroup 9, while limiting the number of conjugates. The present invention therefore relates to new immunogenic compositions for use in pneumococcal vaccines and to vaccination of human subjects, in particular infants and elderly, against pneumoccocal infections using said immunogenic compositions.

Isolated peptides comprising one or more antigenic sites of filovirus glycoprotein and methods of their use and production are disclosed. Nucleic acid molecules encoding the peptides are also provided. In several embodiments, the peptides can be used to induce an immune response to filovirus glycoprotein, such as Zaire ebolavirus glycoprotein, in a subject, for example, to treat or prevent infection of the subject with the virus.
