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

    Nan Liu, Yaxiong Yang ... Xiaodong Liu
    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.

    Structure of a TRPM2 channel in complex with Ca2+ explains unique gating regulation

    Zhe Zhang, Balázs Tóth ... László Csanády
    The 3Å structure and correlated functional analysis of the TRPM2 cation channel from Nematostella vectensis shed light on the molecular mechanisms of TRPM2 regulation by intra- and extracellular Ca2+, and of inactivation of human TRPM2.

    A computational model predicts sex-specific responses to calcium channel blockers in mammalian mesenteric vascular smooth muscle

    Gonzalo Hernandez-Hernandez, Samantha C O'Dwyer ... Colleen E Clancy
    A computer model predicts different mechanisms of blood pressure regulation and effective hypertensive therapy for males and females, thereby serving as a foundational tool for improved treatment precision.

    Molecular tuning of sea anemone stinging

    Lily S He, Yujia Qi ... Nicholas W Bellono
    Sea anemones use adapted ion channels to control stinging behavior.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey, Rudi Tong, Nigel Emptage
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    α1-Adrenergic receptor–PKC–Pyk2–Src signaling boosts L-type Ca2+ channel CaV1.2 activity and long-term potentiation in rodents

    Kwun Nok Mimi Man, Peter Bartels ... Johannes W Hell
    The α1-adrenergic receptor augments the activity of the L-type Ca2+ channel CaV1.2 through PKC and the tyrosine kinases Pyk2 and Src and thereby synaptic plasticity.

    AKT isoforms have distinct hippocampal expression and roles in synaptic plasticity

    Josien Levenga, Helen Wong ... Charles A Hoeffer
    Three distinct AKT isoforms are found in the brain and show dissimilar patterns of expression, differential roles in the expression of synaptic plasticity, and different roles in neuronal signaling.

    Septal cholinergic input to CA2 hippocampal region controls social novelty discrimination via nicotinic receptor-mediated disinhibition

    Domenico Pimpinella, Valentina Mastrorilli ... Marilena Griguoli
    Acetylcholine, released from cholinergic fibers originating from the medial septum, shapes social memory, and controls the CA2 hippocampal circuit via nicotinic receptors localized on GABAergic interneurons.

    Dendritic sodium spikes are required for long-term potentiation at distal synapses on hippocampal pyramidal neurons

    Yujin Kim, Ching-Lung Hsu ... Nelson Spruston
    At distal synapses onto hippocampal CA1 pyramidal neurons, synaptic plasticity is dependent on dendritically initiated sodium spikes, thus establishing a new role for voltage-gated sodium channels in the dendrites that may have important implications for how learning rules are implemented.

    Kv2.1 mediates spatial and functional coupling of L-type calcium channels and ryanodine receptors in mammalian neurons

    Nicholas C Vierra, Michael Kirmiz ... James S Trimmer
    A potassium channel, as a nonconducting function, organizes compartmentalized neuronal calcium signaling microdomains via structural and functional coupling of plasma membrane and endoplasmic reticulum calcium channels.
