The survival of Drosophila amacrine neurons is controlled by neurotrophic signaling mediated by interactions between the cell surface protein DIP-γ and its partner Dpr11, which is expressed on presynaptic photoreceptors.
Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.
Genetic, developmental and pharmacological analysis in Caenorhabditis elegans demonstrate that ATAT-2 tubulin acetyltransferase activity regulates synapse maintenance by acting within the RPM-1 signaling network, but independent of the DLK-1 MAP3K.
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.
Investigation of synapse development using a single neuron system illuminates how individual neurons specify connectivity with their postsynaptic partners and the central role of the synaptic organizer neurexin in this process.
Plexin controls the spatial distribution of synapses by locally inhibiting Rap2 small GTPase activity along the axon, and a Rap2 effector, TNIK, which also plays a key role in inhibiting synapse number.
