    Analysis of protein phosphorylation in nerve terminal reveals extensive changes in active zone proteins upon exocytosis

    Mahdokht Kohansal-Nodehi et al.
    Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt et al.
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.

    Robo2 regulates synaptic oxytocin content by affecting actin dynamics

    Savani Anbalagan et al.
    Real-time monitoring of oxytocin-loaded vesicles and synaptic actin dynamics in zebrafish reveal that Slit3-Robo2-Cdc42 signalling maintains steady-state levels of mature oxytocin neuropeptide readily primed to be secreted upon physiological demand.

    Endothelial heterogeneity across distinct vascular beds during homeostasis and inflammation

    Ankit Jambusaria et al.
    Vascular endothelial cells in the brain, heart and lung exhibit tissue-specific heterogeneity and plasticity, expressing genes that were traditionally thought to be only expressed by the surrounding parenchymal tissue cells.

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

    Kie Itoh et al.
    Genetic and cell biological analyses reveal a new role of Drp1 in postsynaptic endocytosis during brain development beyond mitochondrial division GTPase.

    Elevated synaptic vesicle release probability in synaptophysin/gyrin family quadruple knockouts

    Mathan K Raja et al.
    Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.

    Reactive oxygen species regulate activity-dependent neuronal plasticity in Drosophila

    Matthew CW Oswald et al.
    Reactive oxygen species, previously considered damaging agents linked to pathology, are required for normal neuronal plasticity, including adjustment of synaptic terminal size, maintenance of synaptic physiology and adaptive behavioural responses.

    Small molecule induced oligomerization, clustering and clathrin-independent endocytosis of the dopamine transporter

    Tatiana Sorkina et al.
    Dopamine transporter (DAT) interaction with furopyrimidine called AIM-100 in intact cells leads to dramatic oligomerization, nanoclustering and endocytosis of DAT by a novel mechanism coupled to the transporter molecule conformation.

    Active presynaptic ribosomes in the mammalian brain, and altered transmitter release after protein synthesis inhibition

    Matthew S Scarnati et al.
    Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.
