    Structural mechanism of ligand activation in human calcium-sensing receptor

    Yong Geng, Lidia Mosyak ... Qing R Fan
    L-amino acids are agonists of calcium-sensing receptor, and act jointly with calcium and phosphate ions to control receptor function.

    Structural determinants of voltage-gating properties in calcium channels

    Monica L Fernández-Quintero, Yousra El Ghaleb ... Bernhard E Flucher
    Structure modeling, site-directed mutagenesis, and current recordings revealed the mechanism by which stabilization of voltage sensors in the resting and activated states determines the gating properties of the CaV1.1 calcium channel.

    Calcium-mediated shaping of naive CD4 T-cell phenotype and function

    Vincent Guichard, Nelly Bonilla ... Cédric Auffray
    Calcium-calcineurin signaling cascade drives the acquisition of both the phenotype of the most self-reactive naive CD4 T cells and their enhanced cell-intrinsic ability to commit into induced regulatory T cells upon activation.

    Dendritic branch structure compartmentalizes voltage-dependent calcium influx in cortical layer 2/3 pyramidal cells

    Andrew T Landau, Pojeong Park ... Bernardo L Sabatini
    Elaborate dendritic branch patterns lead to a local and branch-specific reduction in impedance, which attenuates back-propagating action potentials and limits voltage-gated calcium influx.

    Intravital quantification reveals dynamic calcium concentration changes across B cell differentiation stages

    Carolin Ulbricht, Ruth Leben ... Anja E Hauser
    Heterogeneity in cytoplasmic calcium concentration alongside B cell activation and differentiation is measured intravitally using an interdisciplinary imaging approach and novel numerical analysis.

    Calcium depletion challenges endoplasmic reticulum proteostasis by destabilising BiP-substrate complexes

    Steffen Preissler, Claudia Rato ... David Ron
    Regulation of the endoplasmic reticulum chaperone BiP by calcium.

    Calcium dynamics regulating the timing of decision-making in C. elegans

    Yuki Tanimoto, Akiko Yamazoe-Umemoto ... Koutarou D Kimura
    A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.

    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou, Kevin R Neville ... Stephen N Gomperts
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    Molecular mechanisms of gating in the calcium-activated chloride channel bestrophin

    Alexandria N Miller, George Vaisey, Stephen B Long
    Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.

    Excitatory neurotransmission activates compartmentalized calcium transients in Müller glia without affecting lateral process motility

    Joshua M Tworig, Chandler J Coate, Marla B Feller
    During development, lateral processes of retinal Müller glia are highly motile, and this motility persists when retinal waves and calcium transients are blocked, suggesting that Müller glial morphology is established independent of neuronal activity.
