The Pseudomonas autoinducer N-(3-oxododecanoyl)
homoserine lactone induces cyclo-oxygenase-2 and prostaglandin E2 production in human lung fibroblasts: Implications for inflammation.
AHLs contain a common
homoserine lactone ring, differing in their carbon lenght (4 to 18 carbons), degree of saturation, and the presence of C3 acyl chain modifications.
Gram-negative bacteria utilize the autoinducer-1 involving N-acyl
homoserine lactone (AHL) and Gram-positive bacteria utilize the posttranslationally modified oligopeptide signaling molecules classified as autoinducer-2 [1, 4].

homoserine lactone provokes hyperinflammatory responses from cystic fibrosis airway epithelial cells.
For example, red algae secrete halogenated furanones and enones that act as antagonists of acylated
homoserine lactone signaling molecules present in biofilms.
A receptor protein from the LuxR family of transcriptional regulators, upon binding an acylated
homoserine lactone compound, interacts with the lux box, modulating the activity of the promoter.
