Possible Interaction: Gamma-Aminobutyric Acid and Triiodothyronine

Research Papers that Mention the Interaction

GABA supplementation also significantly elevated the triiodothyronine (T3) hormone level and hemoglobin levels and decreased the heterophil–lymphocyte ratio (H/L ratio) (p <.0001).

Tonic currents evoked by low GABA concentrations were also reduced by T3 (40±5%, n=14), but not by T4.
Neuropharmacology  •  2011  |  View Paper
We have previously shown that triiodothyronine (T3) inhibits gamma-aminobutyric acid type A (GABA(A)) receptors in synaptoneurosomes and transfected cells.

Studies of the effects of thyroid hormones on the uptake of neurotransmitters by homogenates of rat cerebral cortex have revealed a significant competitive inhibition of neuronal uptake of [3H]GABA by thyroid hormones ( T3 greater than T4 greater than rT3).
The IC50 for inhibition of GABA uptake by T3 was estimated at 4 microM and that of T4 at 11 microns.

Specific (per mg protein) activity … glutamic acid decarboxylase and of GABA uptake into neurons was reduced by the more physiologic (50 or 500 ng/ml) concentrations of T3 , probably due to a non‐neuronal increase in overall protein synthesis, since the total per culture values seem unaffected by hormone.
