These results suggest that the DA neuroprotection provided by DM in the inflammation-related neurodegenerative models is not mediated through the NMDA receptor.

Detailed Description

Liu et al. (2003) have reported that DM protected dopamine (DA) neurons against inflammation-mediated degeneration. Zhang et al.'s (2004) novel finding was that 1-10 μM DM protected DA neurons against...
