Abstract

Composiciones de vacunas de Neisseria, su fabricación, y el uso de dichas composiciones en medicina. Más particularmente se refiere a procedimientos de fabricación de nuevas cepas meningocócicas modificadas genéticamente que son más adecuadas para la producción de vacunas de vesículas (o ampolla) de membrana externa, de Neisseria, en particular meningocócica. Reivindicación 1: Una preparación de ampollas de Neisseria derivada de una cepa de Neisseria con un inmunotipo LOS L2 o de una cepa de neisseral con un inmunotipo L3 LOS y en la que la cepa es IgtB-; o una preparación en ampolla de Neisserial que comprende una combinación de ampollas derivadas de una cepa neisserial con un inmunotipo L2 LOS y una cepa neisserial con un inmunotipo L3 LOS, en la que opcionalmente cada cepa es IgtB- Reivindicación 6: La preparación de ampollas de Neisseria de las reivindicaciones 1-5, en la que la (s) cepa (s) de Neisseria tienen 1 o más de los siguientes genes de proteína de membrana externa regulado hacia niveles menores de expresión, y preferiblemente suprimidos, comparados con la (s) cepa (s) nativa a partir de las que se derivan: porA, porB, opA., opC, pilC o frpB; y en la que cuando las ampollas L2 y L3 están ambas presentes, las cepas de las que se derivan tienen preferiblemente el (los) mismo (s) gen (es) de proteína de membrana externa regulados hacia niveles menores de expresión en cada cepa. Reivindicación 7: La preparación de ampollas de Neisseria de la reivindicación 6, en la que la (s) cepa (s) de Neisseria tienen cualquiera de las siguientes combinaciones de genes de proteína de membrana externa regulado hacia niveles menores de expresión, y preferiblemente suprimidos, comparados con la (s) cepa (s) nativas (s) a partir de las que se derivan: PorA y OpA, PorA y OpC, OpA y OpC, PorA y OpA y OpC, PorA y FrpB, OpC y FrpB, OpA y FrpB, PorA y OpA y OpC y FrpB. Reivindicación 8: La preparación de ampollas de Neisseria de las reivindicaciones 1-7, en la que la (s) cepa (s) de Neisseria tienen 1 o más de los siguientes antígenos de proteína de membrana externa regulados hacia niveles mayores de expresión: NspA, TbpA bajo, TbpA alto, Hsf, Hap, OMP85, PilQ, NadA, LbpA, MltA; y en la que donde las ampollas L2 y L3 están presentes, las cepas de las que se derivan tienen preferiblemente uno o más antígenos diferentes de proteína de membrana externa regulados hacia niveles mayores de expresión en cada cepa. Reivindicación 9: Una preparación de ampollas de Neisseria derivada de una cepa de Neisseria que ha tenido dos o más de las proteínas de membrana externa reguladas hacia niveles menores de expresión, y preferiblemente suprimidas, comparadas con la cepa nativa de la que se deriva: PorA, PorB, OpA, OpC, PllC o FrpB. Reivindicación 21: Una preparación de ampollas de una cepa de bacterias Gram-negativas en al membrana externa de la que se integra una proteína de membrana externa conjugada a LOS. Reivindicación 32: La preparación de ampollas de las reivindicaciones 21-31 derivada de una cepa de Moxarella catarrhalis o de Haemophilus influenzae no caracterizable.Neisseria vaccine compositions, their manufacture, and the use of such compositions in medicine. More particularly it refers to manufacturing processes of new genetically modified meningococcal strains that are more suitable for the production of Neisseria, in particular meningococcal, outer membrane vesicles (or bleb) vaccines. Claim 1: A Neisseria ampoule preparation derived from a Neisseria strain with an LOS L2 immunotype or a neisseral strain with an L3 LOS immunotype and wherein the strain is IgtB-; or a Neisserial ampoule preparation comprising a combination of ampoules derived from a neisserial strain with an L2 LOS immunotype and a neisserial strain with an L3 LOS immunotype, wherein optionally each strain is IgtB- Claim 6: The preparation of ampoules of Neisseria of claims 1-5, wherein the Neisseria strain (s) have 1 or more of the following external membrane protein genes regulated toward lower levels of expression, and preferably suppressed, compared to the (s) ) native strain (s) from which they are derived: porA, porB, opA., opC, pilC or frpB; and in which when the ampoules L2 and L3 are both present, the strains from which they are derived preferably have the same outer membrane protein gene (s) regulated towards lower levels of expression in each strain. Claim 7: The Neisseria ampoule preparation of claim 6, wherein the Neisseria strain (s) have any of the following combinations of outer membrane protein genes regulated toward lower levels of expression, and preferably suppressed , compared to the native strain (s) from which they are derived: PorA and OpA, PorA and OpC, OpA and OpC, PorA and OpA and OpC, PorA and FrpB, OpC and FrpB, OpA and FrpB, PorA and OpA and OpC and FrpB. Claim 8: The Neisseria ampoule preparation of claims 1-7, wherein the Neisseria strain (s) have 1 or more of the following external membrane protein antigens regulated toward higher levels of expression: NspA , TbpA low, TbpA high, Hsf, Hap, OMP85, PilQ, NadA, LbpA, MltA; and wherein where the L2 and L3 ampoules are present, the strains from which they are derived preferably have one or more different outer membrane protein antigens regulated towards higher levels of expression in each strain. Claim 9: A Neisseria ampoule preparation derived from a Neisseria strain that has had two or more of the outer membrane proteins regulated towards lower levels of expression, and preferably suppressed, compared to the native strain from which it is derived: PorA , PorB, OpA, OpC, PllC or FrpB. Claim 21: A blister preparation of a strain of Gram-negative bacteria in the outer membrane of which an outer membrane protein conjugated to LOS is integrated. Claim 32: The blister preparation of claims 21-31 derived from a strain of Moxarella catarrhalis or non-characterizable Haemophilus influenzae.
