Abstract

ABSTRACT
Cystic fibrosis (CF) is a disease characterised by the depletion of Airway Surface Liquid (ASL) height. Lipoxin A4 was found to be effective in restoring ASL back to normal by acting on ENaC. The signalling mechanisms involved in lipoxin effect were investigated by testing the action of a calcium chelator (Bapta-AM) and Protein kinase C inhibitor (GF 109203X) on NuLi-1 and CuFi-1 cells. Drug’s efficacy was monitored by conducting Ussing chamber experiments and confocal microscopy. Results showed that calcium has a major contribution to the lipoxin A4 effects while PKC has a limited role.  However, our data might lack accuracy due to shortage of time to conduct more experiments.
