Early death due to defective neonatal lung liquid clearance in alpha-ENaC-deficient mice

TL;DR: It is shown that ENaC plays a critical role in the adaptation of the newborn lung to air breathing and was abolished in airway epithelia from αENaC(−/−) mice that developed respiratory distress and died within 40 h of birth from failure to clear their lungs of liquid.
Journal ArticleDOI

Pulmonary epithelial sodium-channel dysfunction and excess airway liquid in pseudohypoaldosteronism

TL;DR: It is demonstrated that sodium transport has a role in regulating the volume of liquid on airway surfaces in patients with systemic pseudohypoaldosteronism, a salt-losing disorder caused by loss-of-function mutations in the genes for the epithelial sodium channel.
Journal ArticleDOI

Macrolide antibiotics for cystic fibrosis.

TL;DR: This review aimed to test the hypotheses that macrolide antibiotics, whilst not directly active against Pseudomonas aeruginosa, may have indirect actions against this bacteria and assess the optimal type, dose and duration of Macrolide therapy.
Journal ArticleDOI

Role of gammaENaC subunit in lung liquid clearance and electrolyte balance in newborn mice. Insights into perinatal adaptation and pseudohypoaldosteronism.

TL;DR: It is suggested that gammaENaC facilitates neonatal lung liquid clearance and is critical for renal Na+ and K+ transport, and that low level Na+ transport may be sufficient for perinatal lungLiquid absorption but insufficient to maintain electrolyte balance by the distal nephron.
