【Abstract】Objective To investigate the effects of human interlukin-13 (hIL-13) on the expression of E-selectin and intercellular adhesion molecule-1(ICAM-1) on bovine aortic endothelial cells(BAECs) stimulated by tumor necrosis factor alpha(TNF-α), and to provide experimental basis for hIL-13 inducing immunity endure and relieving the repulsion reaction of xenograft.
Methods BAECs were co-cultured with different concentrations of hIL-13 for 2 h and followed by co-cultured with 4 ng/ml TNF-α for 6 h or 18 h. The expressions of E-selectin and ICAM-1 on BAECs were detected by Cell-ELISA. The effect of hIL-13 on activity of BAECs was detected by MTT colorimetry.
Results BAECs pretreateded with hIL-13 could inhibit the expression of E-selectin and ICAM-1 induced by TNF-α, and showed a doesdependent manner from 5 ng/ml to 20 ng/ml of hIL-13 (P<0.01). The experimental result of BAECs activity measured by MTT proved no significant difference in the activities of BAECs in every experimental groups compared with control group’s.
Conclusion hIL-13 could inhibit the expression of E-selectin and ICAM-1 on BAECs induced by TNF-α, which may contribute to the xenotransplant immune tolerance.
