Emptying and refilling of Ca2+ store in tracheal myocytes as indicated by ACh-evoked currents and contraction
Abstract
Membrane currents and contractions evoked by acetylcholine (ACh) in freshly dissociated canine tracheal myocytes were investigated using the nystatin perforated-patch recording technique. In cells held at -60 mV in the presence of nifedipine, ACh evoked inward current (IACh) and contraction. Caffeine mimicked the effects of ACh. IACh and contractions could be evoked 3-4 min after removing external Ca2+ but were abolished by prolonged exposure …
