    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova et al.
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    The ion selectivity filter is not an activation gate in TRPV1-3 channels

    Andrés Jara-Oseguera et al.
    The TRPV1, TRPV2 and TRPV3 channels are gated on the cytosolic side of the pore, whereas structural changes in the ion selectivity filter associated with activation don't control cation access.

    Mechanisms of virus dissemination in bone marrow of HIV-1–infected humanized BLT mice

    Mark S Ladinsky et al.
    Large-volume light microscopy combined with higher-resolution electron tomography revealed the spatial distribution of virus-producing cells and highlighted mechanisms of HIV-1 dissemination in bone marrow from a small animal model.

    Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

    Maia Kinnebrew et al.
    The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

    Golgi localized β1-adrenergic receptors stimulate Golgi PI4P hydrolysis by PLCε to regulate cardiac hypertrophy

    Craig A Nash et al.
    β-adrenergic receptors at the Golgi apparatus activate a local signaling pathway, not accessed by cell surface receptors, to drive cardiac hypertrophy and could represent a target for heart failure therapy.

    A critical role of VMP1 in lipoprotein secretion

    Hideaki Morishita et al.
    The ER transmembrane protein VMP1 is important for release of lipoproteins from the ER membrane into the ER lumen for secretion.

    Super-resolution microscopy reveals coupling between mammalian centriole subdistal appendages and distal appendages

    Weng Man Chong et al.
    Super-resolved architectural framework of subdistal appendages surprisingly reveals coupling between distal appendages and subdistal appendages.

    Lamina-specific AMPA receptor dynamics following visual deprivation in vivo

    Han L Tan et al.
    Longitudinal imaging of synapses in the brain shows that sensory deprivation differentially modifies specific synapses within individual neurons across distinct layers of the sensory cortex.

    Distinct roles for innexin gap junctions and hemichannels in mechanosensation

    Denise S Walker, William R Schafer
    The innexin protein UNC-7, a homologue of vertebrate pannexins, plays a specific, gap junction-independent role in C. elegans mechanosensation.

    Junction Mapper is a novel computer vision tool to decipher cell–cell contact phenotypes

    Helena Brezovjakova et al.
    Junction Mapper is a powerful new semi-automated software that provides a fingerprint of cell–cell contact morphometry and receptor density alterations.
