We have studied the in vivo effect of the selective agonist for group II metabotropic glutamate receptors (2S, 2'R, 3'R)-2-(2'3'-dicarboxycyclopropyl)glycine (DCG-IV) against MPP+-induced toxicity on rat striatal dopaminergic nerve terminals by using both microdialysis and immunohistochemical techniques. Perfusion of 1 mM DCG-IV during 1 h protected dopaminergic nerve terminals against the degeneration induced by a 15-minute perfusion of 1 mM MPP+. In addition, the microglial cell population was markedly activated 24 h after DCG-IV perfusion. The astroglial cell population was only markedly activated around the microdialysis probe. This protective effect seems to be dependent on protein synthesis since 1 mM cycloheximide, an inhibitor of protein synthesis, abolished the neuroprotective effect of 1 mM DCG-IV against MPP+ toxicity. Perfusion of DCG-IV induced an upregulation of striatal brain-derived neurotrophic factor (BDNF) mRNA expressing cells which were confined precisely around the microdialysis probe. Taken together, our results suggest that the induction and release of brain-derived neurotrophic factor (BDNF) by activated glial cells induced by DCG-IV perfusion may account for its protective action against MPP+-induced dopaminergic terminal degeneration.
