    The mammalian LINC complex component SUN1 regulates muscle regeneration by modulating drosha activity

    Tsui Han Loo, Xiaoqian Ye ... Colin L Stewart
    The LINC complex, that couples the interphase cytoskeleton to the nucleus, regulates the processing of a cluster of miRNAs required for muscle regeneration by recruiting and interacting directly with Drosha.

    Cocaine-induced endocannabinoid signaling mediated by sigma-1 receptors and extracellular vesicle secretion

    Yoki Nakamura, Dilyan I Dryanovski ... Carl R Lupica
    Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.

    Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

    Maia Kinnebrew, Ellen J Iverson ... Rajat Rohatgi
    The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

    DNA damage checkpoint activation impairs chromatin homeostasis and promotes mitotic catastrophe during aging

    Matthew M Crane, Adam E Russell ... Matt Kaeberlein
    Activation of a DNA-damage cell cycle checkpoint during aging causes genome instability and senescence in yeast mother cells.

    Single cell analysis reveals immune cell–adipocyte crosstalk regulating the transcription of thermogenic adipocytes

    Prashant Rajbhandari, Douglas Arneson ... Peter Tontonoz
    Crosstalk between IL10-producing immune cells and adipocytes within adipose tissue is an important determinant of thermogenesis and systemic energy balance.

    Transverse tubule remodeling enhances Orai1-dependent Ca2+ entry in skeletal muscle

    Antonio Michelucci, Simona Boncompagni ... Feliciano Protasi
    Structural and functional analyses show that transverse tubule association with stacks of sarcoplasmic reticulum enhances Orai1-dependent Ca2+ entry to replenish Ca2+ stores, maintain Ca2+ release, and maximize force during exercise.

    Brain-specific Drp1 regulates postsynaptic endocytosis and dendrite formation independently of mitochondrial division

    Kie Itoh, Daisuke Murata ... Hiromi Sesaki
    Genetic and cell biological analyses reveal a new role of Drp1 in postsynaptic endocytosis during brain development beyond mitochondrial division GTPase.

    Native adiponectin in serum binds to mammalian cells expressing T-cadherin, but not AdipoRs or calreticulin

    Shunbun Kita, Shiro Fukuda ... Iichiro Shimomura
    Binding study of native adiponectin existing in serum supported the importance of T-cadherin but not AdipoRs nor calreticulin.

    Transient protein accumulation at the center of the T cell antigen-presenting cell interface drives efficient IL-2 secretion

    Danielle J Clark, Laura E McMillan ... Christoph Wülfing
    A membrane-associated, supramolecular protein complex with dynamically changing components, the central supramolecular activation cluster, regulates the generation of the T cell effector cytokine IL-2 depending on its composition.

    The lysosomal transporter MFSD1 is essential for liver homeostasis and critically depends on its accessory subunit GLMP

    David Massa López, Melanie Thelen ... Markus Damme
    The so far uncharacterized lysosomal transporter protein MFSD1 is essential for liver homeostasis and needs the highly glycosylated GLMP protein as an accessory subunit for stability.
