  • Title: [Study on the inhibition of tea pigments on the adhesion between monocyte and endothelial cells].
    Author: Xuan W, Wang S, Han C, Chen J.
    Journal: Wei Sheng Yan Jiu; 2001 Jan; 30(1):44-6. PubMed ID: 11255763.
    Abstract:
    In order to study the effects of tea pigments (TP) on the adhesion between monocyte and endothelial cells induced by oxidized low density lipoprotein(Ox-LDL), the fluorescence activated cell sorter (FACS) and the cell ELISA were applied. The results showed that TP could inhibit the adhesion between monocyte and endothelial cells(P < 0.05), and the expression of inter cell adhesion molecule(ICAM-1) and vascular cell adhesion molecule (VCAM-1) proteins in a dose dependent manner(P < 0.05). The results suggested that the inhibition of TP on ICAM-1 and VCAM-1 expression was one of the mechanisms of its antiadhesion between monocyte and vascular endothelial cells, as well as that of its antiatherosclerosis.
