asthma, as well as other inflammatory disorders. In the current study we examined the effect of the di-catechol rooperol [(E)-1,5-bis (3',4'-dihydroxyphenyl) pent-4-en-1-yne] on the process of microvascular endothelial cell (MME) activation by TNF-alpha and IFN-gamma. We show that rooperol decreases VCAM-1 and iNOS mRNA levels in cytokine-activated MME with subsequent inhibition of VCAM-1 membrane expression
血管细胞粘附分子1(VCAM-1)和一氧化氮合酶(iNOS)的诱导表达被认为在动脉粥样硬化,哮喘以及其他炎性疾病的发病机理中起作用。在本研究中,我们研究了二儿茶酚rooperol [(E)-1,5-bis(3',4'-dihydroxyphenyl)pent-4-en-1-yne]对微血管内皮细胞过程的影响(MME)被TNF-α和IFN-γ激活。我们显示rooperol降低细胞因子激活的MME中的VCAM-1和iNOS mRNA水平,并随后抑制VCAM-1膜表达,如通过P815细胞对MME单层的粘附以及NO产生所测量的,这反映在培养基中的亚硝酸盐浓度中。
