ProteomicsProteomic analysis of outer membrane vesicle isolation methods with an Escherichia coli tolA mutant using LC MSMS
Outer membrane vesicles (OMVs) produced by Gram-negative bacteria are mediators of cell survival and pathogenesis by facilitating nutrient transport, virulence factor dissemination, and resistance to antimicrobials. Studies of OMV properties often focus on hypervesiculating Escherichia coli mutants ...

ProteomicsOuter membrane vesicle proteome of Aggregatibacter actinomycetemcomitans serotype e strain 173
Aggregatibacter actinomycetemcomitans is an oral and systemic pathogen associated with aggressive forms of periodontitis, and with endocarditis. Outer membrane vesicles (OMVs) released by this species have been demonstrated to deliver effector proteins such as cytolethal distending toxin (CDT) and l...

TranscriptomicsRNA-seq of Pseudomonas putida KT2440 and the derived strain P. putida pig21 treated with 1-octanol and PQS (Pseudomonas quinolone signal), causing chemical membrane stress.
Pseudomonas species have become promising cell factories for the production of natural products due to their inherent robustness. Here, we explored membrane adaptations of Pseudomonas putida KT2440, in particular outer membrane vesicle (OMV) formation in response to 1-octanol, PQS and prodigiosin, ...

ProteomicsStructural dynamics and immunogenicity of the recombinant and outer membrane vesicle-embedded Meningococcal antigen NadA
The structure and conformation adopted by protein vaccine antigens significantly influence the exposure of their antigenic determinants. Structural knowledge of antigens in native state could drive the design of recombinant vaccines that resemble their cognate native forms, although such information...

ProteomicsProteomic analysis of Pseudomonas aeruginosa purified outer membrane vesicle (OMV) extracts exposed to sex steroids
The project aims to elucidate mechanisms driving P. aeruginosa response to sex steroids hormones. An experiment involving outer membrane vesicles (OMV) extraction combined with Mass spectroscopy was performed to identify differences in P. aeruginosa OMVs proteins produced while being exposed to estr...

ProteomicsPorphyromonas gingivalis Outer Membrane Vesicle and cell Proteome in heme excess and heme limited
Porphyromonas gingivalis is an anaerobic, Gram-negative oral pathogen associated with chronic periodontitis. P. gingivalis has an obligate requirement for heme which it obtains from the host. Heme availability has been linked to disease initiation and progression. In this study we used continuous cu...

ProteomicsOuter membrane vesicle and outer membrane of Haemophilus influenzae Rd KW20, Rd ∆yrbE and Rd ∆vacJ
Bacterial outer membrane vesicles (OMVs) have important biological roles in pathogenesis and intercellular interactions, but a general mechanism of OMV formation is lacking. Here we show that the VacJ/Yrb ABC transport system, a proposed phospholipid (PL) transporter, is involved in OMV formation. D...
