    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    Cryo-EM structures of S-OPA1 reveal its interactions with membrane and changes upon nucleotide binding

    Danyang Zhang et al.
    GTP binding induces rearrangement of S-OPA1 assembly on membrane and thus triggers membrane remodeling with reduced curvature.

    Cryo-EM structures and functional properties of CALHM channels of the human placenta

    Katarzyna Drożdżyk et al.
    Members of the calcium homeostasis modulator family expressed in the placenta form large channels with unknown activation properties that harbor a lipid bilayer on the inside of a cylindrical pore.

    CSF1R blockade induces macrophage ablation and results in mouse choroidal vascular atrophy and RPE disorganization

    Xiao Yang et al.
    Vascular degeneration of the choroid and RPE disorganization were associated with pharmacological macrophage ablation, indicating that insufficiency of macrophage function may be a mechanism underlying age- and AMD-associated pathology.

    Rod nuclear architecture determines contrast transmission of the retina and behavioral sensitivity in mice

    Kaushikaram Subramanian et al.
    Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.

    Imaging neuropeptide release at synapses with a genetically engineered reporter

    Keke Ding et al.
    A series of genetically-encoded fluorescent reporters that allow imaging of neuropeptide release in vivo, with sub-second temporal and nerve terminal-level spatial resolution are developed.

    Ciliary Rab28 and the BBSome negatively regulate extracellular vesicle shedding

    Jyothi S Akella et al.
    The RAB-28 GTPase regulates ciliary extracellular vesicle shedding, which may be important for neuron-glia communication.

    Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes

    Emma C Walker et al.
    Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.
