Ligand-gated chloride channelsand voltage-gated chloride channels are target site of insecticides. 配体门控氯离子通道和电压门控氯离子通道都是杀虫剂的作用靶标,配体门控氯离子通道是抑制剂激发膜兴奋性的基础元件,γ-氨基丁酸(GABA)受体是一种氯离子载体复合物,是目前应用的杀虫剂的主要作用位点。
ion channels, anesthetic, generalneurotransmitters, receptors, GABA, neuronsAnaesthetic agents range from simple inert gases to complex synthetic compounds. It is difficult to envisage a unifying mechanism by which all of these agents induce anaesthesia. This review is focused on ligand-gated ion ...
Ligand-Gated Ion Channels Ligand-gated ion channels are large, multisubunit (4 or 5 subunits) receptors that form a membrane ion channel that, when open, allows the passage of Na+, K+, Ca++, or Cl−. Once the receptor/channel complex is activated, the membrane potential may become depo...
Free Essay: Ligand-gated ion channels, such as GABAA receptors, generate a current by moving ions through the pore of the channel across the membrane. Ion...
Many important ion channels are ligand-gated, and they show a great degree of homology at the genetic level. The Ligand-gated ion channels are classified into three superfamilies: The Cys-loop receptors anionic GABAA α1(GABRA1), α2(GABRA2), α3(GABRA3), α4(GABRA4), α5(GABRA5), ...
However, the prokaryotic ances- tors of these receptors contain no such loop and the term pen- tameric ligand-gated ion channel (pLGIC) is gaining acceptance in the literature [145]. The ionotropic glutamate and P2X receptors are tetrameric and trimeric structures, respect...

Ion channel receptors are a vital component of nervous system signalling, allowing rapid and direct conversion of a chemical neurotransmitter message to an electrical current. In recent decades, it has become apparent that ionotropic receptors are regulated by protein-protein interactions with other ion...
