Sputum mucin 1 is increased during the acute phase of chronic obstructive pulmonary disease exacerbation

Abstract

Unlike pure bacterial induced lung inflammation, both sputum MUC1 CT and EC fragments are increased during acute exacerbation of COPD. The clinical benefits from measuring the changes of various sputum MUC1 fragments in AECOPD need to be elucidated in future studies.
