Chronic methionine sulfoximine administration reduces synaptosomal aspartate and glutamate in rat striatum.


Methionine sulfoxime (MS) is an inhibitor of glutamine synthetase, an astroglial enzyme believed to be involved in the maintenance of glutamine, a major precursor for neurotransmitter pools of the excitatory amino acids aspartate and glutamate in striatal afferent axon terminals. MS was infused for 7 days (24 micrograms/day) into the lateral cerebral… (More)
