    APP interacts with LRP4 and agrin to coordinate the development of the neuromuscular junction in mice

    Hong Y Choi et al.
    Proteins implicated in Alzheimer’s disease, including amyloid precursor protein and ApoE receptors, interact with each other and with a signalling molecule called agrin to influence the development of the neuromuscular junction.

    A 3D culture model of innervated human skeletal muscle enables studies of the adult neuromuscular junction

    Mohsen Afshar Bakooshli et al.
    Human skeletal muscle progenitors and motor neurons self-organize in three-dimensional co-culture to form functional neuromuscular junctions that developmentally mature from the embryonic to the adult state.

    Upregulation of neurovascular communication through filamin abrogation promotes ectopic periventricular neurogenesis

    Shauna L Houlihan et al.
    Analyses based on the mouse model of a human genetic disease reveal that the neuron production of cerebral tissue can be boosted by escalated signaling between neural progenitors and the vasculature.

    Tenectin recruits integrin to stabilize bouton architecture and regulate vesicle release at the Drosophila neuromuscular junction

    Qi Wang et al.
    Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.

    A novel synaptic plasticity rule explains homeostasis of neuromuscular transmission

    Gilles Ouanounou et al.
    Skeletal muscle cells constantly monitor their own activity and that of their partner neuron at synapses, enabling them to provide the neuron with feedback regarding neurotransmitter release.

    Dynamic neuromuscular remodeling precedes motor-unit loss in a mouse model of ALS

    Éric Martineau et al.
    Motor axons undergo dynamic branch-specific changes for weeks before complete neuronal degeneration in a model of amyotrophic lateral sclerosis, highlighting the importance of peripheral factors, intrinsic and extrinsic to motoneurons.

    Loss of adult skeletal muscle stem cells drives age-related neuromuscular junction degeneration

    Wenxuan Liu et al.
    Building on previous work (Liu et al., 2015), it is shown that depletion or rescue of adult skeletal muscle stem cells is sufficient to induce or attenuate age-associated neuromuscular junction deterioration respectively.

    Neurexin–Neuroligin 1 regulates synaptic morphology and functions via the WAVE regulatory complex in Drosophila neuromuscular junction

    Guanglin Xing et al.
    Neurexin–Neuroligin1 complex positively regulates F-actin assembly through direct interaction with WAVE complex to control normal synaptic growth and electrophysiological function in Drosophila neuromuscular junction.
