Abstract/OtherAbstract:
Burkholderia cepacia causes pulmonary infection with high mortality in cystic fibrosis (CF) patients which is likely to involve interaction with respiratory epithelium. In this study the pro-inflammatory properties of B. cepacia were examined using a range of respiratory epithelial cell lines. B. cepacia and cell-free culture supernatants were used to stimulate cell lines with (SigmaCFTE29o- and IB3) and without (A549) the CF transmembrane conductance regulator mutation (CFTR), together with corrected cell lines (C38 and S9). Interleukin (IL)-6 and IL-8, but not GM-CSF or IL-1beta, were released from all the cell lines whereas PGE(2) (prostaglandin E(2)) was released from the A549, IB3 and S9 cell lines only. Nuclear factor (NF)-kappaB activation preceded cytokine release and suppression of NF-kappaB activity diminished cytokine release. These studies indicated that B. cepacia secretory products are potent pro-inflammatory agents for respiratory epithelium and suggest functional CFTR is not required for cytokine or prostanoid responses.
