Role of the Na+-driven anion exchanger ABTS-1 in the neurons of nematode worms. In wild-type C. elegans worms, ABTS-1 and the K/Cl cotransporter KCC-2 lower intracellular [Cl−] rendering GABAergic, glutamatergic, and 5-HT-ergic signals inhibitory to neurotransmitter release (A). In abts-1—null worms, the reduced ability to lower intracellular [Cl−] reduces the potency of inhibitory signals (B).
