Regulatory role of p38 MAPK for MCP1 release from activated bronchial epithelial cells by eosinophils
【Abstract】 AIM: To investigate the release of monocyte chemoattractant protein （MCP）1 from the coculture of human bronchial epithelial cells and eosinophils and the related mechanisms. METHODS: MCP1 in culture supernatant was determined by Cytometric Bead Array (CBA) Kit in flow cytometry to compare MCP1 release in bronchial epithelial cells and eosinophils cultured alone or together, and investigate the inhibitive effect of SB 203580, a selective inhibitor of p38 MAPK, on MCP1 release. The reverse transcriptasepolymerase chain reaction (RTPCR) was used to analyze the gene expression of MCP1 in bronchial epithelial cells during coculture with eosinophils and the effect of SB 203580. RESULTS: The interaction of eosinophils and bronchial epithelial cells was found to upregulate the gene expression of MCP1 in epithelial cells. MCP1 in coculture supernatant of bronchial epithelial cells and eosinophils was elevated significantly ［(1266±127) ng/L vs (134±25) ng/L,P
