Pharmacological characterization of the excitatory ‘Cys‐loop’ GABA receptor family inCaenorhabditis elegans

The pharmacological properties of EXP-1 and LGC-35 more closely resemble the ionotropic GABAA -ρ family. However, EXP-1 and LGC-35 exhibit a unique profile that differs from vertebrate GABAA and GABAA -ρ receptors, insect GABA receptors and nematode GABA receptors. As a pair, EXP-1 and LGC-35 may be utilized to further understand the differential molecular mechanisms of agonist, antagonist and allosteric modulation at ionotropic GABA receptors and may aid in the design of new and more specific anthelmintics that target GABA neurotransmission.
