Design and evaluation in mice of a broadly protective meningococcal group B native outer membrane vesicle vaccine
چکیده انگلیسی

A vaccine based on native outer membrane vesicles (NOMV) that has potential to provide safe, broad based protection against group B strains of Neisseria meningitidis has been developed. Three antigenically diverse group B strains of N. meningitidis were chosen and genetically modified to improve safety and expression of desirable antigens. Safety was enhanced by disabling three genes: synX, lpxL1, and lgtA. The vaccine strains were genetically configured to have three sets of antigens each with potential to induce protective antibodies against a wide range of group B strains. Preliminary immunogenicity studies with combined NOMV from the three strains confirmed the capacity of the vaccine to induce a broad based bactericidal antibody response. Analysis of the bactericidal activity indicated that antibodies to the LOS were responsible for a major portion of the bactericidal activity and that these antibodies may enhance the bactericidal activity of anti-protein antibodies.
