Recent studies in the field of GABA metabolism have focused on:
• Enzymes involved in GABA catabolism.
• Regulation of GABA levels by long-term mechanisms of metabolic
control (i.e. gene expression, and protein synthesis and
turnover).
• Regulation of GABA levels by short-term mechanisms of
metabolic control (i.e. pH, Ca21/calmodulin activation, substrate
concentration and feedback inhibition).
• Intracellular and intercellular transport
