Characterization of N-Acyl-homoserine Lactones (AHLs)-Deficient Clinical Isolates of Pseudomonas aeruginosa [PDF]
Indian Journal of Microbiology, 2014 Pseudomonas aeruginosa is an opportunistic pathogen causing severe respiratory infections. Acylated homoserine lactones (AHLs) are self-generated diffusible signal molecules that mediate population density dependent gene expression (quorum sensing, QS) in a variety of Gram-negative bacteria, and several virulence genes of bacterial pathogens are known ...

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation
Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Allergy, EarlyView.ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Organic & Biomolecular Chemistry, 2013 Gram-negative bacteria often use N-acyl-honnoserine lactones (AHLs) as signal molecules to monitor their local population densities and to regulate gene-expression in a process called "Quorum Sensing" (QS). This cell-to-cell communication allows bacteria to adapt to environmental changes and to behave as multicellular communities.

Advances in Spatial Heterogeneity and Cellular Localization Specificity of Intratumoral Bacteria
Cancer Science, EarlyView.Spatial localization of intratumoral bacteria governs their functional roles in tumor progression, metastasis, and treatment responses, with guiding significance for clinical management, as reviewed across three spatial paradigms. ABSTRACT Bacteria in tumors are increasingly recognized to be a part of the tumor microenvironment and their biological ...

The interaction of N-acylhomoserine lactone quorum sensing signaling molecules with biological membranes: implications for inter-kingdom signaling. [PDF]
PLoS ONE, 2010 The long chain N-acylhomoserine lactone (AHL) quorum sensing signal molecules released by Pseudomonas aeruginosa have long been known to elicit immunomodulatory effects through a process termed inter-kingdom signaling.
