N-3-(Oxododecanoyl)-L-homoserine lactone (C12) is a small bacterial signaling molecule secreted by Pseudomonas aeruginosa (PA), which activates mammalian cells through TLR4-independent mechanisms. C12 acts as an immunosuppressant and it has been shown to modulate murine bone marrow-derived dendritic

OBJECTIVE The aim of the present study was to evaluate whether the quorum-sensing molecules of Pseudomonas aeruginosa could induce the production of interleukin-8 (IL-8) in human corneal epithelial (HCE) cells in vitro. METHODS A confluent monolayer of immortalized HCE cells was treated with 12.5 to

Quorum sensing (QS) is a type of cell-to-cell communication. The Pseudomonas aeruginosa QS molecule N-3-(oxododecanoyl)-L-homoserine lactone (3-o-C12-HSL) has the potential to modulate the immune system of its host. However, the mechanism of that activity is yet to be fully characterized. To be able
