maximal value near ⁣25 mV. On the other hand, the sustained Ca2⁢ current was induced by pre-inactivation for less than 10 ms duration. Its activation started near ⁣10 mV and peaked at ⁢20 mV. Co2⁢ (2 mM) suppressed both of these two components, but nifedipine (20μM), L-type Ca2⁢ channel antagonist, blocked only the sustained current. Based on the activation voltage and the pharmacological specificity, the sustained current appears to be similar to L-type ICa...

X), the inhibitory effect of 5-HT was blocked. We also figured out that 5-HT change the channel kinetics of the sEPSC. There was a significant increase in the rise time during the 5-HT application. Our results suggest that 5-HT has an effect on both pre- and postsynaptic site with decreasing neurotransmitter release probability of glutamate and decreasing the sensitivity to glutamate by increasing the rise time of non-NMDA receptor mediated synaptic transmission in the corticostriatal synapses.

Potassium channels in human skin fibroblast have been studied as a possible site of Alzheimer disease pathogenesis. Fibroblasts in Alzheimer disease show alterations in signal transduction pathway such as changes in Ca2⁢ homeostasis and/or Ca2⁢-activated kinases, phosphatidylinositol cascade, protein kinase C activity, cAMP levels and absence of specific K⁢ channel. However, little is known so far about electrophysiological and pharmacological characteristics of...

To study the direct effect of somatostatin (SS) on calcium channel current (IBa) in guinea-pig gastric myocytes, IBa was recorded by using whole-cell patch clamp technique in single smooth muscle cells. Nicardipine (1μM), a L-type Ca2+ channel blocker, inhibited IBa by 98⁑1.9% (n=5), however IBa was decreased in a reversible manner by application of SS. The peak IBa at 0 mV were decreased to 95⁑1.1, 92⁑1.9, 82⁑4.0, 66⁑5.8, 10⁑2.9% at 10⁣10, 10⁣9,...

In the presence of thapsigargin, an inhibitor of SR Ca2⁢ pump, ryanodine-induced increase in ANP release was not observed. Thapsigargin attenuated ryanodine-induced decrease in atrial dynamic changes....

the basal ACh release. Interestingly, NBQX significantly attenuated the evoked release when it was treated with AMPA, although it did not affect the evoked release alone without AMPA. These observations demonstrate that in hippocampal slices, ionotropic glutamate receptors do not modulate the ACh release in cholinergic terminals, whereas in striatal slices, activations of ionotropic glutamate receptors increase the basal ACh release though NMDA may decrease the electrically-evoked ACh release.

by pre-application of L-NNA, a classical competitive inhibitor of nitric oxide synthase (NOS) with no significant isoform selectivity (Lim, 2003). In the present study, we investigated which isoform of NOS affected CO induced stimulation of L-type Ca2⁢ current in human jejunal circular smooth muscle cells. Cells were voltage clamped by whole-cell mode patch clamp technique, and membrane currents were recorded with 10 mM barium as the charge carrier. Before the addition of CO, cells were...

release mechanism was pharmacologically dissected from the Ca2⁢-induced Ca2⁢ release in the SR Ca2⁢ release in the rat ventricular myocytes patch-clamped in a whole-cell mode. SR Ca2⁢ release process was monitored by using forward-mode Na⁢-Ca2⁢ exchange after restriction of the interactions between Ca2⁢ from SR and Na⁢-Ca2⁢ exchange within micro-domains with heavy cytosolic Ca2⁢ buffering with 10 mM BAPTA. During stimulation every 10 s...

We developed a cardiac cell model to explain the phenomenon of mechano-electric feedback (MEF), based on the experimental data with rat atrial myocytes. It incorporated the activity of ion channels, pumps, exchangers, and changes of intracellular ion concentration. Changes in membrane excitability and Ca2⁢ transients could then be calculated. In the model, the major ion channels responsible for the stretch-induced changes in electrical activity were the stretch-activated channels (SACs)....

Carbon monoxide (CO) is low molecular weight oxide gas that is endogenously produced under physiological conditions and interacts with another gas, nitric oxide (NO), to act as a gastrointestinal messenger. The aim of this study was to determine the effects of exogenous CO on L-type calcium channel currents of human jejunal circular smooth muscle cells. Cells were voltage clamped with 10 mM barium (Ba2⁢) as the charge carrier, and CO was directly applied into the bath to avoid perfusion...
