However, in THIP-treated cultures, lindane-induced cytotoxicity was found to be mediated by an action of the insecticide on GABA receptors.

Gamma-hexachlorocyclohexane (gamma-HCH), fipronil and picrotoxinin are noncompetitive antagonists (NCAs) of L-glutamate-gated chloride channels (GluCls), yet their potencies are weaker than those on gamma-aminobutyric acid receptors (GABARs).

The results presented here show that p-1 subunits, and thus GABAc receptors, may represent a very minor population of GABA receptors in these neuronal preparations.
