N-3-oxo-dodecanoyl-L-Homoserine lactone (3-oxo-C12-HSL), a quorum-sensing signaling molecule synthesized by P. aeruginosa and specific B. cepacia complex strains [1][2], facilitates bacterial gene expression modulation in response to cell density escalation and triggers IL-8 production in 16HBE human bronchial epithelial cells [3].
