The transmitter-gated ion channel converts chemical signals, received through neural synaptic gates, to electric signals. The channels in the postsynaptic cells receive the neurotransmitter. The process results in a temporary permeability change and a change in membrane potential, depending on the ...
GABA(C) receptors: Relatively simple transmitter-gated ion channels? The inhibitory neurotransmitter, GABA, activates a variety of receptors in all areas of the CNS. Two major subtypes of GABA receptors are well known: (1) G... GAR Johnston - 《Trends in Pharmacological Sciences》 被引量: 51...
transmitter-gated ion +添加翻译 英文-冰岛文字典 LR are transmitter-gated ion channels opened? When neurotransmitters bind to specific sites on the channel it twists and opens Transmitter-gated ion channels open when neurotransmitters bind to specific receptor sites on the channel, causing it to chang...
Although a great variety of types of ion channels in membranes has become known in recent years, they can still in all cases be separated logically into two classes. These comprise (A) those which open spontaneously or in response to changes in the membr
Gating of Ion Channels by Transmitters: The Range of Structures of the Transmitter-Gated Channels Although a great variety of types of ion channels in membranes has become known in recent years, they can still in all cases be separated logically into two classes. These comprise (A) those which...
Paraoxon (30 microM-1 mM) blocked the ion channels of glycine, gamma-aminobutyric acidA, N-methyl-D-aspartic acid and nicotinic acetylcholine receptors, but not the ion channels of kalnate- and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid-type glutamate receptors. The combined ...
These are ATP-gated ion channels. In their sequences and topology in the membrane they are unlike the subunits of any other transmitter-gated channels. At least 7 P2X subunit types have now been found, and these are further diversified by alternate pre-mRNA splicing forms. Among interesting ...

Fast synaptic transmission depends on the selective ionic permeability of transmitter-gated ion channels. Here we show changes in the ion selectivity of neuronal P2X transmitter-gated cation channels as a function of time (on the order of seconds) and previous ATP exposure. Heterologously expressed ...
Comments on a study conducted by Hai-Long Wang, et al., on neurotransmitter-gated ion channels. Overview of the study by Wang et al.; How the study described the properties of a point mutation in the amphipathic helix (HA) region of the mutant epsilon subunit; Explanation on the actual ...
