The LasB inhibitor decreases the disruption of the nasal epithelial barrier through the extracellular matrix–focal adhesion pathway during the early phase of Pseudomonas aeruginosa infection Open
Early LasB-mediated injury primarily targets the ECM-Focal adhesion genes rather than tight junction genes transcription. LasB inhibition rapidly restores epithelial-barrier structure and function by modulating Focal-adhesion signaling, hi…
