  abstract  = {The effect of measles virus (MV) infection on mRNA expression and protein synthesis of cytokines in human malignant glioma celllines (0-54 and U-251) was investigated. Primary MV infections led in both celllines to the induction of interleukin-1 fJ (ll-1 (3), interleukin-6 (IL-6), interferon-(3 (IFN-fJ), and tumor necrosis factor-a (TNF-a). ln contrast, persistently infected astrocytoma lines continually produced IL-6 (two out of 12 lines high Ievels) and IFN-ß, whereas only 1 out of 121ines synthesized TNF-a and none IL-1ß. The pathways for induction of IL-1fJ and TNF-a expression were not suppressed by the persistent MV infection, since IL-1ß and TNF-a could be induced by external stimuli Jike diacylglycerol analog plus calcium ionophore. lnterestingly, persistently infected astrocytoma cells synthesized considerably higher Ievels of ll-1ß and TNF-a than uninfected cells afteradditional external induction. These results suggest that in the centrat nervous system (CNS) of SSPE patients a percentage of persistently infected astrocytes may continually synthesize IL-6 and IFN-ß, and in the presence of additional external stimuli, as possibly provided by activated lymphocytes, might ovarexpress the inflammatory cytokines IL-1 ß and TNF-a. This may be of pathogenetic significance in CNS diseases associated with persistent MV infections.},
