Resumen:
Ligand-gated ion channel kinetics were studied in mammalian transfected cells encoding adult mouse muscle acetylcholine (ACh) receptors. We measured macroscopic and single-channel currents using the outside-out and cell-attached patch-clamp configurations. Cultured cells were exposed to moderate intensity inhomogeneous static magnetic fields up to 180 mT and measurements were performed for temperatures ranging from 5 to 50 8C. We found no significant changes in ACh-elicited macroscopic or single-channel currents. We observed the expected dependence in current decay constants with temperature, but negligible magnetic field influence on the channels kinetics.
