Synaptic Electrophysiology of the Drosophila Neuromuscular Junction
Chemical synaptic transmission is an importa11t means of neuronal communication in the nervous system. On the arrival of an action potential, the nerve terminal experiences an influx of calcium ions, which in turn trigger the exocytosis of synaptic vesicles (SVs) and the release of neurotransmitters into the synaptic cleft. Transmitters elicit synaptic responses in the postsynaptic cell by bind...
متن کاملOxidative stress induces overgrowth of the Drosophila neuromuscular junction.
Synaptic terminals are known to expand and contract throughout an animal's life. The physiological constraints and demands that regulate appropriate synaptic growth and connectivity are currently poorly understood. In previous work, we identified a Drosophila model of lysosomal storage disease (LSD), spinster (spin), with larval neuromuscular synapse overgrowth. Here we identify a reactive oxyg...
متن کاملIn vivo imaging of the Drosophila larval neuromuscular junction.
In the past decade, a significant number of proteins involved in the developmental assembly and maturation of synapses have been identified. However, detailed knowledge of the molecular processes underlying developmental synapse assembly is still sparse. We have developed an approach that makes extended in vivo imaging of selected proteins in live Drosophila larvae feasible at a single-synapse ...
متن کاملStathmin is required for stability of the Drosophila neuromuscular junction.
Synaptic connections can be stably maintained for prolonged periods, yet can be rapidly disassembled during the developmental refinement of neural circuitry and following cytological insults that lead to neurodegeneration. To date, the molecular mechanisms that determine whether a synapse will persist versus being remodeled or eliminated remain poorly understood. Mutations in Drosophila stathmi...
متن کاملDerailed regulates development of the Drosophila neuromuscular junction.
Neural function is dependent upon the proper formation and development of synapses. We show here that Wnt5 regulates the growth of the Drosophila neuromuscular junction (NMJ) by signaling through the Derailed receptor. Mutations in both wnt5 and drl result in a significant reduction in the number of synaptic boutons. Cell-type specific rescue experiments show that wnt5 functions in the presynap...
