Outer Membrane Vesicle Containing PorA Protein (PorA-containing OMV)
- Target
- PorA-containing OMV
- Molecular classification
- Lipid Bilayer Vesicle, Protein Complex, Vaccine Component
01
Overview
Outer membrane vesicles (OMVs) are nano-sized vesicles released from Gram-negative bacteria, encapsulating periplasmic content. When containing PorA, a major outer membrane protein of *Neisseria meningitidis*, they serve as potent immunogens and are used as vaccine platforms. They facilitate host-pathogen interactions and immune responses.
