Abstract: The present disclosure relates to an immunogenic composition comprising a combination of meningococcal antigens which comprises at least one factor H binding protein (fHBP) A protein, at least one fHBP B protein, at least one Neisseria adhesin A (NadA) protein, and at least one detergent-extracted Outer Membrane Vesicle (dOMV). The meningococcal antigens may be from a Neisseria meningitidis serogroup B. The combination of antigens provided a broad coverage of bacteria strains. Further, the present disclosure relates to the use of the immunogenic composition in methods for eliciting an immune response.

Abstract: The present invention relates to novel polypeptides derived from meningitis proteins, in particular auto-transporters of the subtilinase subclass, and their use in vaccines and vaccine compositions for the prevention and/or treatment of meningitis and meningococcal infections.

Abstract: The present invention relates to novel polypeptides derived from Neisseria meningitidis proteins, in particular auto-transporters of the trypsin-like serine protease subclass, such as IgA1P, App and AusI, and their use in immunogenic compositions i.a., vaccine compositions for the prevention and/or treatment of meningococcal infections. In particular, it provides fragments of IgA1P, App and AusI and polypeptides comprising or consisting of these fragments and fusions thereof, which may be used in immunogenic compositions, for example vaccine compositions.

Abstract: RNA may be transcribed using a nucleotide reagent as the promoter. The reagent may enable RNA to be transcribed without sequence specification and without protein cofactors, by means of an RNA polymerase that is known to be DNA-dependent such as the RNA polymerase of the phage T7, or by means of new, mutated RNA polymerase with the ability to synthesize a transcription product of polynucleotide matrix with a higher yield when the matrix is RNA than when the matrix is DNA. This type of RNA polymerase can be obtained by effecting mutations on a coding gene for a wild-type RNA polymerase, and then by selecting the mutated RNA polymerase with the ability. The invention can be applied notably to the detection, synthesis or quantification of RNA.

Abstract: Disclosed is a process for transcribing RNA using a nucleotide reagent as the promoter. Such a reagent enables any type of RNA to be transcribed without sequence specification and without protein cofactors, by means of an RNA polymerase that is known to be DNA-dependent such as the RNA polymerase of the phage T7, or by means of new, mutated RNA polymerase with the ability to synthesize a transcription product of a polynucleotide matrix with a higher yield when the matrix is RNA than when said matrix is DNA. This type of RNA polymerase can be obtained by effecting mutations on a coding gene for a wild-type RNA polymerase, and then by selecting the mutated RNA polymerase with said ability. The invention can be applied notably to the detection, synthesis or quantification of RNA.
