    Mutual inhibition among postmitotic neurons regulates robustness of brain wiring in Drosophila

    Marion Langen, Marta Koch ... Bassem A Hassan
    The Notch signaling pathway has a central role in the development of the nervous system, and also in the establishment of networks of connections in the adult brain

    The C-terminal helix 9 motif in rat cannabinoid receptor type 1 regulates axonal trafficking and surface expression

    Alexandra Fletcher-Jones, Keri L Hildick ... Jeremy M Henley
    An intracellular H9 motif facilitates the highly localised axonal surface expression of CB1R.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders, Luiselys M Hernandez ... Gareth M Thomas
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    Dysregulated Dscam levels act through Abelson tyrosine kinase to enlarge presynaptic arbors

    Gabriella R Sterne, Jung Hwan Kim, Bing Ye
    Targeting Abelson kinase can be beneficial for treating disorders characterized by dysregulated Down Syndrome Cell Adhesion Molecule signaling.

    Frazzled promotes growth cone attachment at the source of a Netrin gradient in the Drosophila visual system

    Orkun Akin, S Lawrence Zipursky
    Direct observation in the developing fly brain indicates that the response of a growth cone in a gradient of a guidance cue is adhesion to the source of the cue rather than attraction by the gradient.

    Inhibiting poly(ADP-ribosylation) improves axon regeneration

    Alexandra B Byrne, Rebecca D McWhirter ... Marc Hammarlund
    In C. elegans and mouse neurons, the balance between poly(ADP-ribose) glycohydrolases and poly(ADP-ribose) polymerases regulates axon regeneration downstream of DLK-1/MAPKKK signaling.

    Seizures, behavioral deficits, and adverse drug responses in two new genetic mouse models of HCN1 epileptic encephalopathy

    Andrea Merseburg, Jacquelin Kasemir ... Bina Santoro
    Two genetic mouse models for HCN1-linked developmental epileptic encephalopathy display distinct biophysical changes in HCN1 ion channel properties but similar worsening of seizures in response to antiepileptic drugs, thereby recapitulating key features of the human disease.

    Filopodial dynamics and growth cone stabilization in Drosophila visual circuit development

    Mehmet Neset Özel, Marion Langen ... P Robin Hiesinger
    Long-term live imaging in intact developing Drosophila brains reveals a role for N-Cadherin-mediated fast filopodial dynamics and growth cone stabilization during neural circuit assembly.
    1. Neuroscience

    Specific and comprehensive genetic targeting reveals brain-wide distribution and synaptic input patterns of GABAergic axo-axonic interneurons

    Ricardo Raudales, Gukhan Kim ... Z Josh Huang
    A lineage-based intersectional genetic approach reveals brain-wide distribution and input connectivity of axo-axonic interneuron cells and establishes experimental access to study the circuit function of a ground truth cell type.

    Co-targeting myelin inhibitors and CSPGs markedly enhances regeneration of GDNF-stimulated, but not conditioning-lesioned, sensory axons into the spinal cord

    Jinbin Zhai, Hyukmin Kim ... Young-Jin Son
    Myelin-associated inhibitors and chondroitin sulfate proteoglycans are not the primary mechanism stopping sensory axons regenerating into the spinal cord, although their removal can markedly enhance regeneration when combined with an intervention that elevates axon growth capacity sufficiently robustly.
