Outer membrane vesicles as platform vaccine technology
Outer membrane vesicles (OMVs) are released spontaneously during growth by many Gram-negative bacteria. They present a range of surface antigens in a native conformation and have natural properties like immunogenicity, self-adjuvation and uptake by immune cells which make them attractive for application as vaccines against pathogenic bacteria. In particular with Neisseria meningitidis, they hav...
متن کاملOuter Membrane Vesicles as a Candidate Vaccine against Edwardsiellosis
Infection with Edwardsiella tarda, a gram-negative bacterium, causes high morbidity and mortality in both marine and freshwater fish. Outer membrane vesicles (OMVs) released from gram-negative bacteria are known to play important roles in bacterial pathogenesis and host immune responses, but no such roles for E. tarda OMVs have yet been described. In the present study, we investigated the prote...
متن کاملBacterial Outer Membrane Vesicles and Vaccine Applications
Vaccines based on outer membrane vesicles (OMV) were developed more than 20 years ago against Neisseria meningitidis serogroup B. These nano-sized structures exhibit remarkable potential for immunomodulation of immune responses and delivery of meningococcal antigens or unrelated antigens incorporated into the vesicle structure. This paper reviews different applications in OMV Research and Devel...
متن کاملExtraction of Outer membrane Vesicles from Vaccinal Strain of Bordetella Pertussis as the First Step of a Vaccine Candidate Study Against Pertussis Infection
Background: Pertussis is still one of the major public health problems. The increase of the disease emerged in recent decades due to the replacement of the reactogenic whole cell vaccine with the safer acellular vaccine and the genetic diversity of the bacterium. As outer membrane vesicles (OMVs) obtained from Bordetella pertussis contains surface immunogenic antigen in its structure, it has an...
متن کاملOuter membrane vesicles are vehicles for the delivery of Vibrio tasmaniensis virulence factors to oyster immune cells.
Vibrio tasmaniensis LGP32, a facultative intracellular pathogen of oyster haemocytes, was shown here to release outer membrane vesicles (OMVs) both in the extracellular milieu and inside haemocytes. Intracellular release of OMVs occurred inside phagosomes of intact haemocytes having phagocytosed few vibrios as well as in damaged haemocytes containing large vacuoles heavily loaded with LGP32. Th...
