갑상선 기능 항진증 심장에서의 β-adrenoceptor의 역할은 잘 알려져 있으나 α-adrenoceptor에 대해서는 알려져 있지 않은 바, 저자 등은 갑상선 기능 항진증 기니픽 심장의 유두근에서 일반 미세 전극과 이온-선택적 미세 전극을 이용하여 세포내 Na+과 H+ 활성도에 대한 phenylephrine의 영향을 연구하였다. Phenylephrine (10-5 또는 3 × 10-5M)에 의한 α1-Adrenoceptor 자극은 다양한 활동전위의 변동, 수축기 막전위의 과분극 (1.5 ± 0.1mM), 세포내 활성도 증가 (0.4 ± 0.15mM), 현저한 수축력 증가 (220 ± 15%) 그리고... -

synaptosomal plasma membrane vesicles (SPMV) isolated from bovine cerebral cortex, and liposomes of total lipids (SPMVTL) and phospholipids (SPMVPL) extracted from the SPMV. An experimental procedure was used based on selective quenching of 1,3-di(1-pyrenyl)propane (Py-3-Py) and 1,6-diphenyl-1,3,5-hexatriene (DPH) by trinitrophenyl groups, and radiationless energy transfer from the tryptophans of membrane proteins to Py-3-Py. LidocaineㆍHCl increased the bulk lateral and rotational mobility of... -

6 of aliphatic chains in phospholipids of the outer monolayers. Furthermore, the methanol increased annular lipid fluidity and also caused membrane proteins to cluster. The important finding is that was far greater increase by methanol in annular lipid fluidity than increase in lateral and rotational mobilities by the methanol. Methanol alters the stereo or dynamics of the proteins in the lipid bilayers by combining with lipids, especially with the annular lipids. In conclusion, the present data... -

This study was undertaken to elucidate the underlying mechanisms of ATP depletion-induced membrane transport dysfunction and cell death in renal proximal tubular cells. ATP depletion was induced by incubating cells with 2.5 mM potassium cyanide (KCN)/0.1 mM iodoacetic acid (IAA), and membrane transport function and cell viability were evaluated by measuring Na＋-dependent phosphate uptake and trypan blue exclusion, respectively. ATP depletion resulted in a decrease in Na＋-dependent phosphate... -

of the synaptosomal plasma membrane vesicles (SPMV) isolated from whole bovine brain. In a dose-dependent manner, dopamine decreased the anisotropy (γ), limiting anisotropy (γ∞) and order parameter (S) of DPH in the membranes. These indicate that dopamine increased the rotational mobility of the probe in the neuronal membranes. Cationic 1-[4-(trimethylammonio)-phenyl]-6-phenylhexa-1,3,5-hexatriene (TMA-DPH) and anionic 3-[p-(6- phenyl)-1,3,5-hexatrienyl]-phenylpropionic acid (PRO-DPH) were... -

containing 10 mM EGTA, the RMP was depolarized and did not show STHPs. The membrane currents showed no STOCs but only showed slowly inactivating outward currents. External TEA (1 mM) reversibly inhibited the STHPs, depolarized the RMP, reduced the membrane currents, abolished STOCs, and decreased the open probability of single KCa channel. When KV currents were isolated, the application of 4-AP (5 mM) depolarized the RMP. The important aspect of our results is that KCa channel is responsible for... -

scavengers did not alter the ethanol effect. A potent antioxidant DPPD and iron chelators did not prevent the inhibition. Pyrazole, an inhibitor of alcohol dehydrogenase, did not attenuate ethanol-induced inhibition of Na-Pi uptake, but it prevented ethanol-induced cell death. These results suggest that ethanol may inhibit Na-Pi uptake through a direct action on the carrier protein, although the transport system is affected by alterations in the lipid environment of the membrane. -

Brucella abortus is a bacterium that causes brucellosis and is the causative agent of worldwide zoonoses. Pathogenesis of the B. abortus infection is complicated, and several researchers have attempted to elucidate the infection mechanism of B. abortus. While several proteins have been revealed as pathogenic factors by previous researchers, the underlying mechanism of B. abortus infection is unresolved. In this study, we identified proteins showing different expression levels in B. abortus...
