Activation of inwardly-rectifying k+ channels in hypothalamic POMC neurons: role in integrating synaptic and metabolic input
Hypothalamic proopiomelanocortin (POMC) neurons are critical for controlling homeostatic functions in mammals. We used a transgenic mouse model in which the POMC neurons were labeled with enhanced-green fluorescent protein (EGFP) to perform visualized, whole-cell patch recordings from pre-pubertal female hypothalamic slices. The mouse POMC-EGFP neurons expressed the same endogenous conductance ...
متن کاملGi3 mediates somatostatin-induced activation of an inwardly rectifying K+ current in human growth hormone-secreting adenoma cells.
SRIF activates an inwardly rectifying K+ current in human GH-secreting adenoma cells. Activation of this K+ current induces hyperpolarization of the membrane and abolishment of action potential firing. This mechanism is an essential mechanism for SRIF-induced decrease in intracellular Ca2+ concentration and inhibition of GH secretion. The activation of the inwardly rectifying K+ current is medi...
متن کاملOutward currents through the inwardly rectifying potassium channel of guinea-pig ventricular cells.
Currents through the inwardly rectifying K channel were studied under whole-cell clamp of collagenase-treated single ventricular cells of guinea-pigs. The inwardly rectifying K channel was fully activated by hyperpolarizing the membrane from the equilibrium potential for K+ (EK) by 30-40 mV. Following depolarization above EK, a decaying outward current was elicited. Prolongation of the hyperpol...
متن کاملCurrent self-complianced and self-rectifying resistive switching in Ag-electroded single Na-doped ZnO nanowires.
We demonstrate current self-complianced and self-rectifying bipolar resistive switching in an Ag-electroded Na-doped ZnO nanowire device. The resistive switching is controlled by the formation and rupture of an Ag nanoisland chain on the surface along the Na-doped ZnO nanowire. Na-doping plays important roles in both the self-compliance and self-rectifying properties.
