摘要：
AIM: To examine the effects of rhinovirus and lipopolysaccharide (LPS) on mucin secretion from bronchial tissue and epithelial cells in vitro. METHODS: Human small bronchial tissue fragments (HSBTF) and human bronchial epithelial cells (HBEC) were cultured with rhinovirus 16 and LPS, respectively and culture supernatants were collected for mucin measurement. To determine mucin levels in the culture supernatants, a MUC5AC enzyme linked immunosorbent assay and an enzyme linked lectin assay procedure with dolichos biflorus agglutinin (DBA) were developed, and mucin release was expressed as percentage increased (or decreased) secretion over baseline level. RESULTS: A concentration-dependent release of DBA mucin and MUC5AC mucin were observed when HSBTF were infected with various concentrations of rhinovirus 16 at 37℃. The maximum-induced DBA mucin and MUC5AC mucin release were approximately 258 % and 83 % over baseline. The response of HSBTF to rhinovirus was completely abolished by metabolic inhibitors. Rh
