    Mechanistic basis of the inhibition of SLC11/NRAMP-mediated metal ion transport by bis-isothiourea substituted compounds

    Cristina Manatschal et al.
    The structural and mechanistic characterization of competitive inhibition of human DMT1 offers a promising route for the development of compounds for the treatment of iron overload disorders.

    Precise excitation-inhibition balance controls gain and timing in the hippocampus

    Aanchal Bhatia et al.
    Delayed inhibition precisely balances excitation from arbitrary combinations of CA3 neurons and controls the gain of CA1 output by reducing inhibitory delay with increasing excitation.

    Synergistic interactions with PI3K inhibition that induce apoptosis

    Yaara Zwang et al.
    A geneome-scale shRNA screen identifies five genes whose suppression promotes cell death upon PI3K inhibition both in vitro and in vivo, thus suggesting potential combination therapies involving PI3K inhibition.

    Cell-type-specific control of basolateral amygdala neuronal circuits via entorhinal cortex-driven feedforward inhibition

    E Mae Guthman et al.
    Sst+ interneurons drive feedforward inhibition in the basolateral amygdala, and thus provide a framework for why interneuron subtypes may mediate different archetypal circuit motifs across different brain regions.

    BK channel inhibition by strong extracellular acidification

    Yu Zhou et al.
    Analysis of iconic and gating currents of wild type and mutated BK channels reveals a strong inhibition of this channel by extracellular acidification and elucidates the underlying mechanism that is potentially applicable to other voltage-dependent cation channels.

    Inhibition gates supralinear Ca2+ signaling in Purkinje cell dendrites during practiced movements

    Michael A Gaffield et al.
    In behaving mice, inhibition from molecular layer interneurons attenuates excitation of Purkinje cells by parallel fibers and suppresses their ability to enhance climbing fiber-triggered dendritic Ca2+ responses.

    Inhibition in the auditory brainstem enhances signal representation and regulates gain in complex acoustic environments

    Christian Keine et al.
    Inhibition in the brainstem has further roles beyond temporal sharpening and improves reproduction for a multitude of sounds.

    Spinal V2b neurons reveal a role for ipsilateral inhibition in speed control

    Rebecca A Callahan et al.
    Two anatomically and genetically distinct subtypes of spinal V2b neurons provide inhibition onto motor circuits and serve as a brake on locomotor speed.

    Cooperative and acute inhibition by multiple C-terminal motifs of L-type Ca2+ channels

    Nan Liu et al.
    C-terminus mediated inhibition is one emerging modality of intervention for L-type Ca2+ channels, which coordinate multiple motifs to acutely tune Ca2+ current and Ca2+ influx down to the lower limits preset by end-stage Ca2+-dependent inactivation.

    Non-selective inhibition of inappropriate motor-tendencies during response-conflict by a fronto-subthalamic mechanism

    Jan R Wessel et al.
    Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.
