대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2014, Vol.18 No.6 11 517-524 (8 pages)
Phasic and tonic γ-aminobutyric acidA (GABAA) receptor-mediated inhibition critically regulate neuronal information processing. As these two inhibitory modalities have distinctive features in their receptor composition, subcellular localization of receptors, and the timing of receptor activation, it has been thought that they might exert distinct roles, if not completely separable, in the regulation of neuronal function. Inhibition should be maintained and regulated depending on changes in... -

of HERG channels was voltage-dependent, with a steep increase over the voltage range of the channel opening. However, the inhibition exhibited voltage independence over the voltage range of fully activated channels. CsA blocked the HERG channels predominantly in the open and inactivated states rather than in the closed state. Results of the present study suggest that CsA acts directly on the HERG channel as an open-channel blocker, and it acts independently of its effect on calcineurin activity. -

The interaction of cyclosporine A (CsA), an immunosuppressant, with rat brain Kv1.5 (Kv1.5) channels, which were stably expressed in Chinese hamster ovary cells, was investigated using the whole-cell patch-clamp technique. CsA reversibly blocked Kv1.5 currents at 50 mV in a reversible concentration- dependent manner with an apparent IC50 of 1.0μM. Other calcineurin inhibitors (cypermethrin, autoinhibitory peptide) had no effect on Kv1.5 and did not prevent the inhibitory effect of CsA.... -

intracellular or extracellular application of cytolysin formed ion-permeable pores with a single channel conductance of 37.5⁑4.0 pS. The pore currents were consistently maintained after washout of cytolysin. Replacement of Na in bath solution with monovalent ions (K, Cs or TEA) or with divalent ions (Mg2, Ca2) did not affect the pore currents.When the NaCl concentration in bath solution was lowered from 140 to 60 and 20 mM, the reversal potential... -

inside-out patches excised into solution containing 10 mM EDTA to rule out the effect of Mg2 on the channel gating. The substate(s) could be recorded with all mutants D172H, D172K and D172R. The unitary current-voltage (I-V) relation was not linear with D172H at pHi 6.3, whereas the unitary I-V relation was linear at pHi 8.0. The relative occupancy at SLC was increased from 0.018 at pHi 8.0 to 0.45 at pHi 5.5. In H-N dimer, that was increased from 0.016 at pHi 8.0 to 0.23 at pHi 5.5. The... -

We have studied mutant forms of Kir2.1 in which an aspartate residue (D172), important for gating by intracellular polyamines, is replaced by one of three basic residues (Arg, Lys or His). Such channels are highly selective for K+, but show inward rectification that is a shallow function of voltage compared with that found in wild type. This inward rectification occurs with a reduced affinity for spermine and persists in the absence of polyamines. Though the unitary current-voltage relation... -

action by ATP, showing that thiol oxidation was not involved in the blocking mechanism of ATP. There were no statistical difference in the single channel conductance for the oxidized and reduced states of the channel. Analysis of the open and closed time distributions showed that DTNB had no effect on open and closed time distributions shorter than 4 ms. On the other hand, DTNB decreased the life time of bursts and increased the interburst interval. N-ethylmaleimide (NEM), a substance that... -

high K (90 mM) external solution, which was also blocked by glibenclamide. The metabolic inhibition by the treatment with mitochondrial respiratory chain inhibitors (rotenone and antimycin) hyperpolarized the resting membrane potential of parasympathetic neurons, which was not observed in sympathetic neurons. The hyperpolarizing response to metabolic inhibition was partially blocked by glibenclamide. RT-PCR analysis revealed that MPG neurons mainly expressed the KATP channel subunits of... -

It is not known whether gender differences play a role in susceptibility to ischemic acute renal failure. Thus, we examined if there were any differences in susceptibility between male and female mice to kidney ischemic injury, and if so, whether it is due to differences in mitogen activated protein kinases (MAPKs) or inflammatory responses to ischemia. Female mice were protected against kidney ischemia when compared with males. Thirty minutes of bilateral ischemia resulted in marked functional... -

In the present study, the postnatal developmental changes in the expressional levels of cardiac sarcoplasmic reticulum (SR) Ca2 regulatory proteins, i.e. Ca2-ATPase, phospholamban, and Ca2 release channel, were investigated. Both SR Ca2-ATPase and phospholamban mRNA levels were about 35% of adult levels at birth and gradually increased to adult levels. Protein levels of both SR Ca2-ATPase and phospholamban, which were measured by quantitative immunoblotting,... -

and 0 mM Ca2 containing Tyrode solution increased the frequency-related amplitude accommodation only in the rabbit LA. Monenisn was also able to increase the frequency-related amplitude accommodation only in 1-day old rat LA but not in 4-week old rat LA that had 75% less Na/Ca2 exchanger with 97% higher SR than 1-day old rat LA. Taken together, it is concluded that the differences in the prevalence between myocardial Na/Ca2 exchanger and SR in the amplitude...
