This study shows that targeting catecholate siderophore systems reduces AIEC colonization in colitis by immunization, preserving gut microbiome composition.

The paper identifies microbial bile acid conjugation as a drug-activating function for 5-ASA, revealing its therapeutic relevance through metabolomics analysis.

This study identifies Escherichia coli as a key driver of B cell accumulation in Peyer's patches via CXCR2-dependent mechanisms involving curli amyloid fibers and TLR2 signaling.

This study shows that PgtE protease in virulent Salmonella Typhimurium helps evade complement-mediated killing by cleaving C3, enabling systemic spread.

The paper creates a spectral library of N-acyl lipids from metabolomics data, identifies novel compounds, and links them to health conditions like HIV and cognitive impairment.
