Abstract

In the present study, we investigated whether lipopolysaccharide induce mucin release and erythro-mycin affect basal and adenosine triphosphate-induced (stimulated mucin release, from airway goblet cells. Confluent primary hamster tracheal surface epithelial cells were metabolically radiolabeled and chased for 30 min or 24 hr in the presence of varying concentrations of lipopolysaccharide or erythromycin to assess the effects on $^3H$-mucin release. The results were as follows : 1) Lipopolysaccharide failed to induce mucin release, 2) Erythromycin showed no effect on both basal and stimulated mucin release during 30 min of 24 hr treatment period. We conclude that lipopolysaccharide and erythromycin can not affect mucin release by direct acting on airway mucin-secreting cells.
