Huntington's disease (HD) is an autosomal dominant, inherited and fatal neurodegenerative disorder for which there is, at present, no effective treatment or cure. Striatal medium spiny neurons (MSN) are the most sensitive in HD. Dysregulation of glutamate/calcium signaling pathway emerges as a possible cause of striatal MSN neurodegeneration in HD. Here we evaluated five clinically relevant glutamate pathway inhibitors using previously developed in vitro HD model. We found that folic acid, gabapentin and lamotrigine did not protect HD neurons from glutamate-induced cell death, but memantine and riluzole were protective. Our results provide further support to potential use of memantine and riluzole for treatment of HD.
