Action of halothane on large-conductance, calcium-activated potassium channels in rat cerebrovascular smooth muscle cells
… part by the opening of large conductance, Ca²⁺-activated potassium channels (BK channels) in cerebral artery smooth muscle cells. The present experiments utilized extra cellular patch clamp techniques to investigate whether clinically relevant concentrations of halothane directly alter the …

Nongenomic Effects of Estrogens on Epithelial Chloride Secretion.
… chloride secretion by elevating intracellular calcium. 17α-estradiol, a stereoisomer that does not activate nuclear estrogen receptors, is equipotent with 17β-E2. Other non-estrogen steroids produce much less, if any, potentiation of calcium-stimulated chloride secretion. The estrogen receptor …

Regulation Of Neuronal Excitability: New Mechanisms For Slow Afterhyperpolarization Activation And Modulation
… I<sub>sAHP</sub> is known to be mediated by calcium-activated potassium channels, however, neither the identity of the channel underlying this current nor its mechanism of activation are yet well understood. Recent reports have questioned a direct role of calcium in the activation of the …

Ion channels and electrical excitability in native murine anterior pituitary corticotrophs
… excitable cells with a number of ion channels and signaling pathways implicated in the control of their electrical properties and ACTH secretion. However, the mechanisms involved in native corticotrophs are poorly understood partly due to the current limitations of identifying …

Detection of SK2 Channels on Hippocampal Neurons
<p>Calcium-activated small conductance potassium channels (SK) are crucial for synaptic plasticity, sleep, and learning and memory (Hammond, Bond et al. 2006; Cueni, Canepari et al. 2008; Lin, Lujan et al. 2008). Despite the recent progress on SK channel physiology, the precise spatial organization …

Interactions of insecticidal spider peptide neurotoxins with insect voltage- and neurotransmitter-gated ion channels
… neurotoxins that target insect large-conductance calcium-activated potassium channels (BKCa) have been isolated from the venom of two unrelated spiders. The ƙ-TRTX-Ec2 toxins are a family of three homologous peptides isolated from the African tarantula, Eucratoscelus longiceps and ƙ-HXTX-Hv1c is …

Studies on preconditioning with adenosine, glutamate and ouabain in rat hippocampal slices
… by activation of A1 receptors and ATP-sensitive potassium channels whilst excitotoxic preconditioning mainly involves stimulation of NMDA receptors, nitric oxide and most likely ATP-sensitive potassium channel activation. ATP-sensitive potassium channel openers such as pinacidil and diazoxide are …
