    Intrinsic mechanisms in the gating of resurgent Na+ currents

    Joseph L Ransdell, Jonathan D Moreno ... Jeanne M Nerbonne
    Experimental and modeling results reveal that the activation of resurgent sodium currents relies on the recovery of inactivated channels into a conducting state, and that the decay of resurgent currents reflects the accumulation of these channels into a slow-inactivated state.

    Heterozygous expression of a Kcnt1 gain-of-function variant has differential effects on somatostatin- and parvalbumin-expressing cortical GABAergic neurons

    Amy N Shore, Keyong Li ... Matthew C Weston
    An epilepsy-associated potassium channel variant causes neuron-type-dependent alterations in ionic currents, neuronal excitability, and network connectivity.

    Cannabidiol activates neuronal Kv7 channels

    Han-Xiong Bear Zhang, Laurel Heckman ... Bruce P Bean
    The phytocannabinoid cannabidiol, an antiepileptic agent whose molecular targets are unclear, was found to potently enhance current carried by cloned human Kv7.2/7.3 channels and native M-current in mouse and rat neurons.

    The mechanism underlying transient weakness in myotonia congenita

    Jessica H Myers, Kirsten Denman ... Mark M Rich
    Transient weakness in myotonia congenita is caused by depolarization secondary to activation of persistent Na+ current in skeletal muscle.

    SUMOylation of NaV1.2 channels regulates the velocity of backpropagating action potentials in cortical pyramidal neurons

    Oron Kotler, Yana Khrapunsky ... Ilya Fleidervish
    In cortical pyramidal neurons, subtype-specific SUMOylation of Na+ channels regulates input-output relationships, synaptic boosting, and action potential propagation from the axonal trigger zone back into the dendrites.

    A-type FHFs mediate resurgent currents through TTX-resistant voltage-gated sodium channels

    Yucheng Xiao, Jonathan W Theile ... Theodore R Cummins
    A-type fibroblast growth factor homologous factors generate resurgent currents in tetrodotoxin-resistant voltage-gated sodium channels, increase repetitive firing of sensory neurons, and provide a potentially important target for pain treatment strategies.

    Calpain fosters the hyperexcitability of motoneurons after spinal cord injury and leads to spasticity

    Vanessa Plantier, Irene Sanchez-Brualla ... Frédéric Brocard
    Calpain is a promising therapeutic target to reduce spasticity after a spinal cord injury.

    Biophysical mechanisms in the mammalian respiratory oscillator re-examined with a new data-driven computational model

    Ryan S Phillips, Tibin T John ... Jeffrey C Smith
    Computational modeling motivated by recent experiments clarifies biophysical mechanisms generating the rhythm and amplitude of breathing at the level of neurons and brain circuits in mammals.

    Two opposite voltage-dependent currents control the unusual early development pattern of embryonic Renshaw cell electrical activity

    Juliette Boeri, Claude Meunier ... Antonny Czarnecki
    A simple mechanism, based on the synergy of two major opposing voltage-dependent currents that are ubiquitous in neurons, produces functional diversity of developing Renshaw cells in the embryo.

    NBI-921352, a first-in-class, NaV1.6 selective, sodium channel inhibitor that prevents seizures in Scn8a gain-of-function mice, and wild-type mice and rats

    JP Johnson, Thilo Focken ... James R Empfield
    NBI-921352 (formerly XEN901) is a precision medicine in development for individuals with SCN8A gain-of-function mutations causing SCN8A related epilepsy syndrome (SCN8A-RES), as well as other epilepsy indications, include adult focal onset seizures (FOS).
