Alcohol abuse, which can impair clearance of pathogens and debris from the airway, is associated with an increase in complications and a higher mortality rate during the progression of pneumonia. With prolonged alcohol exposure, mucociliary clearance (MCC), which depends on the coordinated beating of cilia, is dysfunctional. Effective MCC relies on cAMP-dependent protein kinase (PKA) activation of ciliary beat frequency (CBF). PKA activation and stimulation of CBF are blunted with chronic exposure to alcohol. This phenomenon is known as alcohol-induced ciliary dysfunction (AICD). Previous studies have shown that concomitant feeding of mice with alcohol and antioxidants prevents AICD, suggesting a …
