Figure 5From: L-glutamate released from activated microglia downregulates astrocytic L-glutamate transporter expression in neuroinflammation: the ‘collusion’ hypothesis for increased extracellular L-glutamate concentration in neuroinflammation ATP did not contribute to the downregulation of GLAST in the inflammation without cell death. (A, B) Neither ATP nor the P2X7 agonist BzATP affected L-Glu uptake. (C, D) Neither the P2X receptor antagonist TNP-ATP nor the P2X7 specific antagonist BBG affected the LPS-induced decrease in L-Glu uptake. **P < 0.01 vs. control group (n = 6), Tukey’s test following ANOVA.Back to article page
