  1. 1. Elucidating the Gating Mechanism of Cys-Loop Receptors

    Author : Özge Yoluk; Erik Lindahl; Philip Biggin; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ion channel; gating; simulation; molecular dynamics; receptor; cys-loop; modelling; Teoretisk kemi och biologi; Theoretical Chemistry and Biology; Biological Physics; Biologisk fysik;

    Abstract : Cys-loop receptors are membrane proteins that are key players for the fast synaptic neurotransmission. Their ion transport initiates new nerve signals after activation by small agonist molecules, but this function is also highly sensitive to allosteric modulation by a number of compounds such as anesthetics, alcohol or anti-parasitic agents.

  2. 2. Voltage sensor activation and modulation in ion channels

    Author : Christine S Schwaiger; Lindahl Erik; Paolo Carloni; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; activation; deactivation; inactivation; voltage sensor; VSD; gating; Kv1.2-2.1; Shaker; F233; hydrophobic barrier;

    Abstract : Voltage-gated ion channels play fundamental roles in neural excitability, they are for instance responsible for every single heart beat in our bodies, and dysfunctional channels cause disease that can be even lethal. Understanding how the voltage sensor of these channels function is critical for drug design of compounds targeting neuronal excitability. READ MORE

  4. 4. Scaling and Gating Attosecond Pulse Generation

    Author : Christoph Heyl; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent imaging; Ultrafast electron dynamics; Single attosecond pulses; Attosecond pulse trains; XUV sources; High-order harmonic generation; XUV frequency combs; Fysicumarkivet A:2014:Heyl;

    Abstract : High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. READ MORE

  5. 5. Conformational Changes during Potassium-Channel Gating

    Author : Jakob Renhorn; Fredrik Elinder; David Engblom; Stephan Pless; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ion-channel; electrophysiology; neuron; Jonkanal; neurologi; elektrofysiologi; neuron; aktionspotential;

    Abstract : Voltage-gated ion channels have a paramount importance in many physiological processes such as cell-to-cell communication, action potential-propagation, and cell motility. Voltage-gated ion channels are characterized by their ability to sense membrane voltage and to greatly change channel activity in response to small changes in the voltage. READ MORE
