conclusions the results showed that the extracted omvs were conformationally stable, and there were no pyrogenic determinants in omv. also the results showed that the omv elicited high level of specific antibodies against n. meningitidis serogroup a. these results indicate that the omv obtained here, can be used as a meningococcal vaccine after further investigation. materials and methods omvs ...
Objective(s): Enterotoxigenic Escherichia coli (ETEC) is an important cause of diarrheal disease in humans, particularly in children under 5 years and travelers in developing countries. To our knowledge, no vaccine is licensed yet to protect against ETEC infection. Like many Gram-negative pathogens, ETEC can secrete outer membrane vesicles (OMVs). These structures contain various immunogenic vi...
cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. the main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. in this work, the cel...

We investigate translocation dynamics of a vesicle cell under collision with a Janus or a homogeneous hydrophobic/hydrophilic nanoparticle. To this end, we perform dissipative particle dynamics simulation by setting the nanoparticle with different initial velocities, different chemical patterns of the surface for the nanoparticle, and different orientations (for the Janus nanoparticle). Particu...
background outer membrane protein d (pd) is a highly conserved and stable protein in the outer membrane of both encapsulated (typeable) and non-capsulated (non-typeable) strains of haemophilus influenzae. as an immunogen, pd is a potential candidate vaccine against non-typeable h. influenzae (nthi) strains. objectives the aim of this study was to determine the cytokine pattern and the opsonic a...
Centrifugation-based assays are commonly employed to study protein-membrane affinity or binding using lipid bilayer vesicles. An analogous assay has been developed to study nanoparticle-membrane interactions as a function of nanoparticle surface functionalization, membrane lipid composition, and monovalent salt concentration (NaCl). Anionic (carboxylic acid, Ag-COOH), cationic (amine, Ag-NH), a...
