Outer Membrane Vesicles as a Versatile Platform for Vaccine Development: Engineering Strategies, Applications and Challenges Outer membrane vesicles (OMVs) are nanosized vesicles naturally secreted by Gram-negative bacteria and represent a promising platform for vaccine development. OMVs possess inherent immunostimulatory ...

🚨I'm happy to share our latest review on outer membrane vesicles (OMVs) as a promising platform for vaccine development in the Journal of Extracellular Vesicles. 💉

The immune response modulated by inoculation of commensal bacteria at birth impacts the gut microbiota and prevents Salmonella colonization Super- and low-shedding phenomena have been observed in genetically homogeneous hosts infected by a single bacterial strain. To decipher the mechanisms underlying these phenotypes, we conducted an ...

Happy to share our last paper. We show that the inoculation of 4 commensal bacteria to chicks has both short- and long-term effects on immune response and microbiota composition and promoted the low-shedder phenotype thanks to a more fermentative microbiota.
