Differential Levels of Glutamate Dehydrogenase 1 (GLUD1) in Balb/c and C57BL/6 Mice and the Effects of Overexpression of the Gene on Glutamate Release in Striatum

open access: yesASN Neuro, 2011
We have previously shown that overexpression of the Glud1 (glutamate dehydrogenase 1) gene in neurons of C57BL/6 mice results in increased depolarization-induced glutamate release that eventually leads to selective neuronal injury and cell loss by 12 ...
