ABSTRACT
We have reported that cultured human umbilical cord vein endothelial cells (HUVEC) differ from endothelium present on vein surface of organ culture (OC) in production of cytokines and susceptibility to viral infections. In this paper we present the effect of viral infections on interferon (IFN), tumor necrosis factor (TNF), and interleukin 6 (IL-6) production in two culture systems HUVEC and OC. Infection of 24-48 h HUVEC with herpes simplex type 1 (HSV-1) and vesicular stomatitis virus (VSV) reduced the amounts of IL-6 and TNF produced in comparison to those released spontaneously by uninfected cells. No IFN was detected in media from infected and uninfected HUVEC. Limited viral infections of 3-h-HUVEC and OC usually diminished their efficiency of IL-6 and TNF production. In the case of IL-6 synthesis by OC, effect of viral infection depended, however, on the constitutive synthesis of the cytokine. When spontaneous production was high (> 800 U/ml), VSV and HSV-1 infection reduced IL-6 level by 2-50 times; in the case of low production (< 150 U/ml) the stimulation effect (2-4 fold) was observed. OC released spontaneously some IFN activity (2-32 U/ml). HSV-1 infection of OC reduced IFN level, while VSV in single cases slightly upregulated IFN synthesis.
