Long terminal repeats (5'-LTR) contain essential enhancer and promoter elements that act as targets for cellular and viral regulatory proteins. The interplay of these cis-acting sequences with specific transcription factors (NF kappa B, Ap1, and Sp1) present in infected cells determines the rate of transcription initiation from the 5'-LTR promoter element,(More)
Ivermectin (IVM) is a macrocyclic lactone that exerts antifilarial, antiparasitic, and insecticidal effects on nematodes and insects by acting on l-glutamic acid-gated chloride channels (GluCls). IVM also acts as an allosteric modulator of various other ion channels. Although the IVM binding site in the Caenorhabditis elegans GluCl was identified by X-ray(More)
Fluralaner (Bravecto) is a recently marketed isoxazoline ectoparasiticide. This compound potently inhibits GABA-gated chloride channels (GABACls) and less potently glutamate-gated chloride channels (GluCls) in insects. The mechanism underlying this selectivity is unknown. Therefore, we sought to identify the amino acid residues causing the low potency of(More)
Glutamate-gated chloride channels (GluCls) are inhibitory neurotransmitter receptors that are present only in invertebrates such as nematodes and insects. These channels are important targets of insecticidal, acaricidal, and anthelmintic macrolides such as avermectins, ivermectin (IVM), and milbemycins. To identify the amino acid residues that interact with(More)
