In 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 کاملDevelopment and plasticity of the Drosophila larval neuromuscular junction.
The Drosophila larval neuromuscular system is relatively simple, containing only 32 motor neurons in each abdominal hemisegment, and its neuromuscular junctions (NMJs) have been studied extensively. NMJ synapses exhibit developmental and functional plasticity while displaying stereotyped connectivity. Drosophila Type I NMJ synapses are glutamatergic, while the vertebrate NMJ uses acetylcholine ...
متن کاملQuantal unit populations at the Drosophila larval neuromuscular junction.
Focal extracellular recording at visualized boutons of the Drosophila larval neuromuscular junction was used to determine frequency and time course of the spontaneously occurring quantal events. When simultaneous intracellular recordings from the innervated muscle cell were made, more than one class of quantal event occurred at some of the individual boutons. "True" signals (arising at the bout...
متن کاملEffects of Buthus eupeus Venom on Neuromuscular Transmission on Striated Muscle In Vitro
In this study, effects of Buthus eupeus venom on chick biventer cervices nerve-muscle preparation were investigated by twitch tension method. The venom, at 1.3 ?g/ml, increased contractile responses in indirect stimulations. These effects were milder in direct muscle stimulations. It also caused significant enhancement in postjunctional sensitivity as assessed by responses to exogenous acetylch...
