Net GABA production is the result of GABA formation through glutamate decarboxylase (GAD) and GABA catabolism involving a GABA-transferase (GABA-T)-mediated shunt to the TCA cycle.

GABA is metabolized through a bypass pathway of the TCA cycle called GABA shunt, which is composed of glutamate decarboxylase (GAD), GABA transaminase (GABA-T) and succinic semialdehyde dehydrogenase (SSADH).

The inactivation of GABA is brought about by high affinity GABA transporters located in the presynaptic GABAergic neurons as well as surrounding astrocytes and subsequently GABA may be metabolized by GABA-transaminase (GABA-T) ultimately allowing the carbon skeleton to enter the tricarboxylic acid (TCA) cycle for oxidative metabolism.

In this study, we observed the neuroprotective effects of ebselen against ischemic damage and on GABA shunt enzymes such as glutamic acid decarboxylase 67 (GAD67), GABA transaminse (GABA-T) and succinic semialdehyde dehydrogenase (SSADH) in the hippocampal CA1 region after 5 min of transient forebrain ischemia in gerbils.

With markedly improved (1) H{(13) C} magnetic resonance spectroscopy technique and the use of high magnetic field strength of 11.7 T accessible to the current study, [4-(13) C] glutamate at 2.35 ppm was spectrally resolved from overlapping resonances of [4-(13) C] glutamine at 2.46 ppm and [2-(13) C] GABA at 2.28 ppm as well as the more distal [3-(13) C] glutamate and [3-(13) C] glutamine.

In cerebellum MW led to the decrease in the levels of glutamine and asparagine and increase in glycine level, followed by the GABA-transaminase activation and the succinate dehydrogenase inhibition.
