Inhibitory effects of muscone on PMNs adherence to HUVEC and the expression of ICAM-1,VCAM-1 and CD44 of HUVEC / 中国免疫学杂志

ABSTRACT

Objective:Based on the model of human umbilical vein endothelial cell(HUVEC) treated by tumor necrosis factor-alfa(TNF),We investigate the effects of muscone on polymophonulear leukocytes(PMN)-HUVEC adhesion and its adhesion molecules(CAMs) expression.Methods:Confocal system was used for identifying cultured HUVEC,MTT assay for its activity,Rose Bengal Staining for PMN-HUVEC adhesion,and fluorescent-immunocytochemistry techniques for CAMs expression.Results:After HUVEC treated by TNF,the adhesion between PMN and HUVEC increased dramatically(P
