Interaction of permeant ions with channels activated by acetylcholine in Aplysia neurones.
Marchais D, Marty A. Marchais D, et al. J Physiol. 1979 Dec;297(0):9-45. doi: 10.1113/jphysiol.1979.sp013025. J Physiol. 1979. PMID: 536927 Free PMC article.
The goal of this work was to test whether permeant ions may bind in a voltage-dependent manner to channel sites and thereby hinder channel closing, as has been proposed before (Ascher, Marty & Neild, 1978a). 2. ...Replacing the divalent cations (Mg and Ca) prese …

Noise analysis suggested that this Ca-dependent current was carried by a large unitary conductance channel, called BK channel, which was previously described in inside-out patches (Marty, 1981). ...At the same time, a fraction of the outward current observed …

Blockage of Ca-activated Cl conductance by furosemide in rat lacrimal glands.
Evans MG, Marty A, Tan YP, Trautmann A. Evans MG, et al. Pflugers Arch. 1986 Jan;406(1):65-8. doi: 10.1007/BF00582955. Pflugers Arch. 1986. PMID: 2419830
This component of the response had been shown in a previous work (Marty et al. 1984) to be due to Ca-dependent Cl channels. The action of furosemide was further studied on cells which were dialysed with a high-Ca, high-Na solution, and which mainly displayed …
