Kinetics of calcium inward current activation
Dear Sir: Recently Lee et al. (1978) and Akaike et al. (1978) have published in this Journa l two very interest ing papers , repor t ing elegant exper iments with the internally per fused nerve cell bodies. We are especially happy with the success of these authors: the idea o f how simple it is to substitute the cytoplasm of the cell body by artificial saline has once more appeared to be frui t...

متن کاملOsteoclast spreading kinetics are correlated with an oscillatory activation of a calcium-dependent potassium current.
Cell movement and spreading involve calcium-dependent processes and ionic channel activation. During bone resorption, osteoclasts alternate between spread, motile and resorptive phases. We investigated whether the electrical membrane properties of osteoclasts were linked to their membrane morphological changes. Rabbit osteoclasts were recorded by time-lapse videomicroscopy performed simultaneou...
متن کاملKinetics and rectification of the slow inward current in the rabbit sinoatrial node cell.
The slow inward current (is) in the rabbit sinoatrial node cell was studied by the conventional two-microelectrode voltage clamp technique. When is was measured as the difference between two records obtained before and after blocking is with D 600, the fully activated current (is)-voltage relation was non-linear; the conductance decreased in the negative potential range resulting in an almost c...
متن کاملVoltage dependence of desensitization. Influence of calcium and activation kinetics
The voltage dependence of carbachol-induced desensitization has been analyzed in potassium-depolarized frog sartorius muscle preparations with voltage clamp techniques over a wide voltage range (-120 to +40 mV). Desensitization developed exponentially at all voltages with tau, the time constant of desensitization onset, varying as a logarithmic function of membrane voltage. The voltage dependen...
