摘要

Astrocytes become activated in response to many CNS pathologies. The process of astrocyte activation remains rather enigmatic and results in so-called reactive gliosis, a reaction with specific structural and functional characteristics. Astrocytes play a vital role in regulating aspects of inflammation and in the homeostatic maintenance of the CNS. However, the responses of different human astroglial cell-lines in viral encephalitis mediated inflammation are not well documented. We have shown that Japanese encephalitis virus (JEV) infection causes morphological and functional changes in astrocytic cell-lines. We have demonstrated that besides reactive oxygen species (ROS) JEV infection differentially regulated the induction pattern of IL-6, IL-1 beta and IL-8. IP-10, MCP-1, MIG and RANTES secretions in different astroglial cell-lines. The expression of different proteins such as astrocyte-specific glial fibrillary acidic protein (GFAP), the glutamate aspartate transporter/essential amino acid transporter-1 (GLAST/EAAT-1), glutamate transporter-1/essential amino acid transporter-2 (GLT-1/EAAT-2), Ceruloplasmin and Thioredoxin (TRX) expression level also differ in different human astrocyte cell-lines following infection.
