Editing Exocytosis (section)

=== Outer-membrane vesicle mediated exocytosis ===
Vesicular exocytosis in prokaryote [[gram-negative bacteria]] is another mechanism that has been found in recent years. Exocytosis, in this case, occurs through release of [[Outer membrane vesicle|outer-membrane vesicles]] (OMV). This contributes to the bacteria's functions, such as pathogenicity and communication. OMV's carry toxins and viral factors to host cells to create inflammatory responses and infection. The vesicles carry molecules that can contribute to immune system modulation.<ref>{{cite web |title=immune system modulator |url=https://www.cancer.gov/publications/dictionaries/cancer-terms/def/immune-system-modulator |website=National Cancer Institute |date=2 February 2011 }}</ref><ref name="Yáñez-Mó-2015" /> Outer-membrane vesicles are able to use a process called [[horizontal gene transfer]] through carrying DNA and RNA between bacterial organisms. This promotes adaptation in the environment and helps bacteria evolve.<ref name="Yáñez-Mó-2015" /> This is unique to gram-negative bacteria and challenges the existing view on exocytosis as an eukaryotic process.
