Beschreibung
Zusammenfassung:	The present invention relates to immunogenic compositions comprising neisserial blebs with upregulated levels of the NMB0964 antigens such that bactericidal antibodies are generated against said antigen. It has been found for the first time that this antigen's expression is zinc regulated and therefore methods are provided to upregulated expression through removal of the zinc repression mechanism of the cell or promoter, or through removal of zinc from the culture medium.
