19766671 Breckenridge CB, Holden L, Sturgess N, Weiner M, Sheets L, Sargent D, Soderlund DM, Choi JS, Symington S, Clark JM, Burr S, Ray D: Evidence for a separate mechanism of toxicity for the Type I and the Type II pyrethroid insecticides. Neurotoxicology. 2009 Nov;30 Suppl 1:S17-31. Epub 2009 Sep 18.

Four of six alpha-cyano pyrethroids (lambda-cyfluthrin, cypermethrin, deltamethrin and fenpropathrin) reduced open chloride channel probability.

These results support the hypothesis that the voltage-dependent chloride channel is a toxicologically significant additional site of action for deltamethrin and that the use of chloride channel agonists can provide a rationale for a novel and effective therapy against type II pyrethroid poisoning.

Following our previous demonstration of actions of deltamethrin on the voltage-gated chloride channel in rats and in neuroblastoma cells, we examined the dose-response relationship for deltamethrin by patch clamp analysis of voltage-gated channels in partially differentiated NIE115 cells.

It therefore appears clear that in some combinations the type I and type II pyrethroids can compete and may bind to the same chloride channel target site.
We have proposed that since the type II pyrethroids deltamethrin and cypermethrin, but not the type I pyrethroid cismethrin act on chloride channels, this could contribute to the bimodal nature of pyrethroid poisoning syndromes.

The results suggest a multiplicity of the GABAA receptor-chloride channel complex.

The type II pyrethroids deltamethrin and fenvalerate augmented the GABA-activated peak chloride current when applied concurrently with GABA, but the effect was diminished as the pyrethroids were applied for long periods of time prior to GABA application.
The GABA-activated chloride channel has been shown to be modulated by general anesthetics, alcohols, and the pyrethroid, cyclodiene and lindane insecticides.

1787887 Eshleman AJ, Murray TF: Pyrethroid insecticides indirectly inhibit GABA-dependent 36Cl- influx in synaptoneurosomes from the trout brain. Neuropharmacology. 1991 Dec;30(12A):1333-41.

Deltamethrin, (1R alpha S)-cis-cypermethrin and permethrin produced a dose-dependent increase in the basal uptake and a corresponding decrease in GABA-dependent influx, with a maximum inhibition of 70-82%.
Thus, pyrethroid insecticides may interfere with the function of GABAA receptors indirectly through an interaction with the voltage-dependent sodium channel in the brain of the trout and consequently perturb chloride influx, possibly through a voltage-dependent chloride channel.
