This protocol demonstrates how to dissect Drosophila larvae in preparation for immunohistochemistry and/or imaging of the neuromuscular junction.
Studying Synaptic Vesicle Pools using Photoconversion of Styryl Dyes
STED Microscopy of Synaptic Function, European Neuroscience Institute Göttingen
FM dyes have been of invaluable help in the understanding of synaptic dynamics. FMs are normally followed under the fluorescent microscope during different stimulation conditions. However, photoconversion of FM dyes combined with electron microscopy allows the visualization of distinct synaptic vesicle pools, among other ultrastructure components, in synaptic boutons.
Drosophila Larval NMJ Immunohistochemistry
Department of Physiology and Cellular Biophysics, Columbia University College of Physicians and Surgeons
This protocol demonstrates how to perform immunohistochemistry on dissected Drosophila larva.
Physiological Recordings of High and Low Output NMJs on the Crayfish Leg Extensor Muscle
Department of Biology, University of Kentucky
This article demonstrates how to conduct electrophysiological recordings of synaptic responses on the extensor muscle in the walking leg of a crayfish and how the nerve terminals are visualized to show the gross morphological differences of high- and low-output nerve terminals.
In vivo Imaging of Intact Drosophila Larvae at Sub-cellular Resolution
1Junior Research Group Synaptic Plasticity, Hertie Institute for Clinical Brain Research, University of Tübingen, 2Graduate School of Cellular and Molecular Neuroscience, University of Tübingen
This protocol describes a reliable method for anesthetization and imaging of intact Drosophila melanogaster larvae. We have utilized the volatile anesthetic desflurane to allow for repetitive imaging at sub-cellular resolution and re-identification of structures for up to a few days1.
Dissection and Imaging of Active Zones in the Drosophila Neuromuscular Junction
Developmental Neurobiology, St. Jude Children’s Research Hospital
The neuromuscular junction (NMJ) of Drosophila melanogaster is an important model system for studying normal synaptic function as well as perturbations to synaptic function found in certain neurological diseases. We present a protocol for dissection of the Drosophila larval motor system and immunostaining for active zone proteins within the NMJ.
Measuring Exocytosis in Neurons Using FM Labeling
Department of Molecular and Cell Biology, Harvard
The ability to measure the kinetics of vesicle release can help provide insight into some of the basics of neurotransmission. Here we used real-time imaging of vesicles labeled with the red fluorescent dye FM 4-64 to measure the rate of presynaptic vesicle release in hippocampal neuronal cultures.
In vivo Micro-circulation Measurement in Skeletal Muscle by Intra-vital Microscopy
1Department of Anesthesiology and Critical Care, Shriners Hospital for Children, Massachusetts General Hospital, and Harvard Medical School, 2Department of Geriatric Medicine, Graduate School of Medicine, The University of Tokyo
A new versatile method for observation of microcirculation is presented. It is considered suitable for long-term observation, and for combination with pharmacophysiological or molecular biological interventions.
Historical View and Physiology Demonstration at the NMJ of the Crayfish Opener Muscle
Department of Biology, University of Kentucky
The opener muscle of the crayfish leg is presented for its historical importance and experimental versatility in muscle phenotype, synaptic physiology and plasticity.
Electrophysiological Methods for Recording Synaptic Potentials from the NMJ of Drosophila Larvae
Department of Physiology and Cellular Biophysics, Columbia University College of Physicians and Surgeons
Here we describe electrophysiological methods for measuring synaptic transmission at the neuromuscular junction of Drosophila larva. Evoked release is initiated artificially by stimulating the motor neuron axons, and transmission through the NMJ can be measured by the postsynaptic response evoked in the muscle.
