Single cholinergic receptor channel currents in cultured human muscle.
Single cholinergic channel currents were recorded in adult human muscle tissue culture. The agonists suberyldicholine and carbamylcholine produce channels with the same conductance as channels produced by acetylcholine but with different closing kinetics. The antagonist tubocurarine, alone or mixed with suberyldicholine, activates channels which close very rapidly. For agonist-activated channel...
متن کاملSingle-channel currents activated by curare in cultured embryonic rat muscle.
Single cholinergic receptor channel currents activated by curare were recorded in tissue-cultured embryonic rat muscle, directly confirming curare's action as a weak cholinergic agonist. In embryonic muscle, curare, in addition to its classical action as a competitive cholinergic antagonist, produces small sustained depolarizations which can be blocked by alpha-bungarotoxin. The single-channel ...
متن کاملSingle channel currents from excised patches of muscle membrane.
The currents through single acetylcholine-activated channels were measured on membrane fragments that had been torn from rat muscle myotubes with patch pipettes. The membrane fragments were sealed into the pipette by using the "gigohm-seal" technique of Neher, which also permitted voltage clamp of the membrane via the patch electrode. Membrane patches were excited by sudden withdrawal of the el...
متن کاملSingle-channel mechanosensitive currents.
Morris and Horn (1) describe ion channel activity, elicited by mechanical stimulation, in both membrane patches and in whole neurons from the snail Lymnaea stagnalis. In whole-cell recordings, mechanical stimulation did not elicit the large macroscopic mechanosensitive currents (IMs) that were anticipated from studies of single mechanosensitive (MS) channels in membrane patches. These negative ...
