Spontaneous, local diastolic subsarcolemmal calcium releases in single, isolated guinea-pig sinoatrial nodal cells
Uptake and release calcium from the sarcoplasmic reticulum (SR) (dubbed "calcium clock"), in the form of spontaneous, rhythmic, local diastolic calcium releases (LCRs), together with voltage-sensitive ion channels (membrane clock) form a coupled system that regulates the action potential (AP) firing rate. LCRs activate Sodium/Calcium exchanger (NCX) that accelerates diastolic depolarization and...
متن کاملAction potential transfer in cell pairs isolated from adult rat and guinea pig ventricles.
An enzymatic procedure was used to obtain ventricular cells from adult rat and guinea pig hearts. Isolated pairs of cells were selected to study the action potential transfer from cell to cell and determine the resistance of the nexal membrane, rn. For this purpose, each cell of a cell pair was connected to a patch pipette so as to enable whole-cell, tight-seal recording. Normal impulse transmi...
متن کاملMembrane potential fluctuations and transient inward currents induced by reactive oxygen intermediates in isolated rabbit ventricular cells.
The cellular basis of reactive oxygen intermediate-induced arrhythmias was investigated in isolated rabbit ventricular cells using the whole-cell voltage- and current-clamp techniques. Singlet oxygen and superoxide were generated by the photoactivation of rose bengal. Single ventricular cells exposed to rose bengal (10-100 nM) exhibited spontaneous membrane potential fluctuations at plateau pot...
متن کاملAmplitude fluctuations in small EPSPs recorded from CA1 pyramidal cells in the guinea pig hippocampal slice.
EPSPs have been evoked in CA1 pyramidal cells by (1) activation of single CA3 neurons (unitary EPSPs), and (2) low-intensity stimuli to the CA1 stratum radiatum. Five unitary EPSPs were obtained; their mean peak amplitudes ranged from 85 to 275 microV and 3 of the 5 showed fluctuations in amplitude that were too great to be attributed to baseline noise. After subtraction of the variance due to ...
متن کاملMechanism of spontaneous intracellular calcium fluctuations in single GH4C1 rat pituitary cells.
Individual unstimulated GH4C1 cells exhibited spontaneous dynamic fluctuations in cytosolic free Ca2+ concentration ([Ca2+]i). Either chelation of extracellular Ca2+ with EGTA or treatment with nifedipine inhibited spontaneous [Ca2+]i fluctuations, indicating that the [Ca2+]i profile was dependent on the entry of extracellular Ca2+ via voltage-operated Ca2+ channels (VOCC). Spontaneous [Ca2+]i ...
