摘要：

The effects of the cytokines tumour necrosis factor-alpha (TNF-alpha, interleukin (IL)-1 beta and IL-6 on the permeability of monolayers of rat cerebral endothelial cells (RCEC) were investigated to assess potential changes in the integrity of the blood-brain barrier (BBB). RCEC were cultured to tight monolayers with a trans endothelial electrical resistance (TEER) of 100-150 Omega . cm(2) on polycarbonate filters. Exposure of the RCEC to TNF-alpha, IL-1 beta and IL-6 induced a decline in the TEER, which could be completely abolished by 1 mu M of indomethacin, a cyclooxygenase inhibitor. In addition, the effect of IL-1 beta on TEER across monolayers of RCEC could be completely inhibited by IL-1 receptor antagonist. In conclusion, cytokines induce a disruption of the BBB in vitro. In this process, cyclooxygenase activation within the endothelial cells seems to play a key role.
