TranscriptomicsGenomic Comparison of the O-antigen Biosynthesis Gene Clusters of E. coli O55 Strains Belonging to Three Lineages.
Typical enteropathogenic Escherichia coli (EPEC) O55:H7 is regarded as the closest relative of enterohemorrhagic E. coli (EHEC) O157:H7. Both serotypes usually express the γ1 intimin subclass and trigger actin polymerazation by the Tir-TccP pathway. However, atypical O55:H7 strains capable of trigg...

ProteomicsWild-type and single-O-antigen repeat outer-membrane vesicles induce equivalent protection against homologous and heterologous Salmonella challenge
Lipopolysaccharide O-antigen is an immunodominant target of protective antibodies. Variation in O-antigen structures limits antibody-mediated cross-protection between closely-related pathogens including Salmonella Typhimurium (STm) and S. Enteritidis (SEn). Bacterial outer membrane vesicles (OMV) ar...

TranscriptomicsMolecular immunophenotyping of lungs and spleens in naive and vaccinated chickens early after pulmonary avian influenza A (H9N2) virus infection
In a respiratory-infection-model with the avian influenza A H9N2 virus, lung and splenic immune reactions in chickens were studied using a 5K chicken immuno-microarray. Groups of chickens were either mock-immunized (referred to as non-immune), vaccinated with inactivated viral antigen only (immune) ...

ProteomicsSimultaneously Identifying and Distinguishing Glycoproteins with O-GlcNAc and the Tn Antigen in Human Cancer Cells
Proteins modified with O-GlcNAc and O-GalNAc (the Tn antigen) play critically important roles in many physiological and pathological processes. Comprehensive and site-specific analysis of proteins modified with O-GlcNAc and the Tn antigen advances our understanding of glycoprotein functions and cell...

TranscriptomicsO-antigen Loss Modulates Meropenem Resistance in Klebsiella pneumoniae Through Metabolic and Redox Reprogramming
Carbapenems are last-line β-lactam antibiotics for multidrug-resistant Gram-negative infections, yet the adaptive routes by which Enterobacterales survive carbapenem stress remain incompletely understood. Here we show that prolonged subinhibitory meropenem exposure promotes O-antigen loss in Klebsie...
