Recent Developments in the Molecular Characterization of the L-Type Ca2+ -Channel and Mitochondrial nding and modulated cardiac and neuronal Ca.-channel function (Callewaert et al., 1989). Evidence exists that heparin may serve important functions (e.g. on endothelial cells) in addition to its role in blood coagulation. In this study we have investigated the effects of heparin on L-type calcium channel labelling and function.鞠躬 发表于 2025-3-27 08:29:13
Na+-Ca2+ and Na+-H+ Antiporter Interactions. Relations between Cytosolic Free Ca2+, Na+ and Intracelmode, forward or reverse, of the antiporter in a particular cell? b) can Na.-Ca. exchange be activated in both modes depending on the ionic balance and the thermodynamic conditions of the cell? and c) is there an interaction between Na.-Ca. and Na.-H. exchange since both depend on the Na. electrochemical potential?聚集 发表于 2025-3-27 10:10:52
Modulation and Functions of Neuronal Ca2+ Permeable Channelsand the Ca. concentration of the extracellular milieu is approximately 10. M. Consequently there is a very large electrochemical gradient for Ca. ions across the plasma membrane of the cell. This membrane is normally very impermeable to Ca.. The Ca. permeability of the plasma membrane can be rapidly说笑 发表于 2025-3-27 16:30:03

Patch Clamp Study of Ca Channels in Isolated Renal Tubule Segmentsegrees in each segment of the nephron (6). While both transcellular and paracellular reabsorptive pathways have been posited, the means by which Ca might cross the apical membrane to enter the tubular cells remains un!-. known; conceivably, this could be by cation exchange, cotransport, a carrier mecompose 发表于 2025-3-28 01:12:22
Recent Developments in the Molecular Characterization of the L-Type Ca2+ -Channel and Mitochondrial s which have been isolated from rat or bovine brain. Hanbauer et al., 1989 e.g. described a putative endogenous ligand which inhibited nitrendipine binding and modulated cardiac and neuronal Ca.-channel function (Callewaert et al., 1989). Evidence exists that heparin may serve important functions (e逢迎春日 发表于 2025-3-28 04:09:12
Evidence for an Intracellular Ryanodine- and Caffeine-Sensitive Calcium Ion-Conducting Channel in Exiculum (SR), via a ligand-gated, high-conductance “Ca. release” channel. This channel has been identified as the receptor for the plant alkaloid ryanodine and also shown to be morphologically identical with the large protein structures (“feet”) that span the gap between junctional SR and the muscle无所不知 发表于 2025-3-28 08:46:48
