Neutrophil Elastase-Mediated CFTR Damage is Rescued by Intracellular Bioavailable GSNO

Ramakrishna B. Boyanapalli, Kirsten M. Look, Doug Looker, Peter F. Bove, and Sherif E. Gabriel

Cystic fibrosis (CF) is an autosomal genetic disorder characterized by mutations within the cystic fibrosis transmembrane conductance regulator (CFTR). Within the airways, CF patients suffer from abnormal ion and fluid transport, leading to an increase in mucus accumulation, infection, and inflammation.

As part of the innate immune response, neutrophils migrate into the airways to initially aid in the clearance of infection. However, neutrophils in the lungs of CF patients release neutrophil elastase (NE), a serine protease which has been shown to degrade lung tissue, and specifically target wild type and  F508del-CFTR for degradation.
