Specific nucleic acids and polypeptides from pathogenic strains of Neisseria

摘要

A polypeptide (I) specific for pathogenic strains of Neisseria, or its antigenic fragment, is new and is identical to or homologous to any of 27 fully defined sequences. Independent claims are also included for the following: (1) an isolated nucleic acid (II) encoding (I) which is not one of the 12 fully defined sequences in the specification; (2) an expression vector (III) containing a cassette that includes (II) expressible in host cells; (3) host cells (IV) transfected with (III); (4) monoclonal antibodies (Ab) directed against (I); and (5) a pharmaceutical composition (V) containing: (a) (II), either naked or associated with a transfection agent; (b) a vaccinating vector containing (II), particularly a virus or bacterium; or (c) (I), optionally combined with a vehicle ACTIVITY : Antibacterial. MECHANISM OF ACTION : Induction of specific immune response.
