  1. 1. Molecular aspects on voltage-sensor movement

    Författare :Amir Broomand; Fredrik Elinder; Guiscard Seebohm; Linköpings universitet; []
    Nyckelord :Potassium channels; voltage-gated; chemistry; metabolism; physiology; patch-clamp techniques; oocytes; MEDICINE; MEDICIN;

    Sammanfattning : Voltage-gated ion channels are fundamental for electrical signaling in living cells. They are composed of four subunits, each holding six transmembrane helices, S1-S6. Each subunit contains a voltage-sensor domain, S1-S4, and a pore domain, S5-S6. LÄS MER

  3. 2. Voltage-Sensor Domains of Ion Channels : Physiology, Regulation, and Role in Disease

    Författare :Michelle Nilsson; Antonios Pantazis; Fredrik Elinder; Henry M. Colecraft; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Brain function depends on the ability of neurons to sense and respond to electricity, which is mediated by small modules in the neuronal membrane called voltage-sensor domains (VSDs). Disruption of VSD function can cause neurological disease such as epilepsy. LÄS MER

  4. 3. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Författare :Staffan Dryselius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER

  5. 4. The Best Leading Role for Maintaining Normal β-cell Function Goes to MafA and Voltage-gated Calcium Channel Subunit γ4

    Författare :Cheng Luan; Diabetes - öpatofysiologi; []

  7. 5. Voltage sensitivity of dopamine D2-like receptors

    Författare :Kristoffer Sahlholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : G protein coupled receptors (GPCRs) mediate a multitude of responses serving hormonal, neurotransmitter, and sensory functions. These receptors are important drug targets; in fact, about 27 % of prescribed drugs are GPCR ligands. LÄS MER
