ADHESION OF LYMPHOCYTES AND EOSINOPHILS IN PERIPHERAL BLOOD OF ASTHMA GUINEA PIG MODEL AND LUNG MICROVASCULAR ENDOTHELIAL CELLS / 解放军医学杂志

To explore the adhesion of peripheral blood lymphocytes and eosinophils and lung microvascular endothelial cells (LMEC) in asthma. Guinea pigs were divided into asthma model group and control group; the adhesion rates of isolated peripheral lymphocytes, eosinophils and the cultured LMEC monolayers were assayed.The mRNA expressions of VCAM 1 and eotaxin in LMEC were determined by RT PCR.The DNA binding activities of NF ?B and AP 1 of LMEC were detected by electrophoretic mobility shifts assay (EMSA). Under the stimulation with serum of asthma group:①the adhesion rates of lymphocytes, activated eosinophils and LMEC were significantly elevated( P
