摘要：

Astrocyte cell cultures were established from human fetal brains and exposed to human recombinant tumor necrosis factor alpha (TNFalpha) and human recombinant interferon gamma (IFNgamma), and the proliferative response was assessed by bromodeoxyuridine-immunostaining technique. TNFalpha showed an inhibitory activity, while IFNgamma induced a slight increase in the number of astrocytes undergoing cell division. However, in both experiments differences were not statistically significant. Previous studies have demonstrated that TNFalpha and IFNgamma are potent mitogens for adult astrocytes in both in vivo and in vitro conditions. Our results suggest that in developing brain the immunomodulatory activity of cytokines, TNFalpha and IFNgamma, is different from that observed in adult brain.
