Abstract

In this study, the effects of TNF binding protein I (TBP I) on TNF- induced changes of human brain microvascular endothelial cells (MVEC) were investigated. TBP I completely abolished TNF-induced IL-6 production and E- selectin induction, while it partially inhibited TNF-induced IL-8 production and up-regulation of ICAM-I and VCAM-I. Moreover, TBP I significantly inhibited TNF-induced cytotoxicity and leukocyte adherence on human brain MVEC. The inhibitory activity of TBP I for TNF was dose-dependent and related to the time of administration after TNF stimulation. In addition, TBP I inhibited membrane-bound TNF induced activation of human brain MVEC, but the concentration required was about 10-fold higher than that for soluble TNF. These results indicate a therapeutic potential for TBP I in diseases of the central nervous system associated with TNF overproduction.
