Assessing Glucose Uptake in the Motor Neurons of Drosophila Larvae with Upregulated Glucose Metabolism
0 Views •
2025
The video demonstrates a technique for measuring glucose uptake in Drosophila larval motor neurons using a fluorescence resonance energy transfer (FRET)-based intracellular glucose sensor. After dissecting the larvae to expose the ventral nerve cord, the motor neurons are visualized through the fluorescence emitted by the sensor's donor fluorophore. When stimulated with glucose, FRET between the sensor's donor and acceptor fluorophores triggers the emission of fluorescence from the acceptor,...

Here we demonstrate a novel assay to study cold nociception in Drosophila larvae. This assay utilizes a custom-built Peltier probe capable of applying a focal noxious cold stimulus and results in quantifiable cold-specific behaviors. This technique will allow further cellular and molecular dissection of cold nociception.

FAQs
Distinction depends on illuminating the specimen with blue or near-ultraviolet light and detecting the cyan light emitted in response. In Cfp positive larvae, this optical readout can be assigned to labeled cells, tissues, or biological activities. Researchers can therefore localize reporter signal within the developing animal instead of relying only on ordinary visual inspection.
The signal can identify where particular genetic or cellular events occur within a developing larva. By following labeled regions, researchers can track gene expression, cell lineage, and tissue development, while changes in fluorescence patterns may also help investigate disease-related processes. Its value comes from connecting visible spatial patterns with developmental or biological changes.
Living specimens support observation of fluorescent patterns as development proceeds, allowing researchers to follow changes over time. Fixed specimens provide an image of the preserved biological state at the selected observation point. Using either format helps match the imaging approach to the question, whether the study emphasizes developmental progression or specimen-specific cellular and tissue organization.
Researchers can compare the presence or distribution of cyan fluorescence between experimental groups as part of microscopy-based phenotyping. These comparisons may reveal differences in labeled gene expression, cell lineage, tissue development, or disease-related processes. The resulting optical patterns help connect an experimental genetic or cellular change with an observable developmental outcome.
A basic workflow includes examining living or fixed larvae under appropriate fluorescence imaging conditions, detecting the cyan emission, identifying specimens or regions with the reporter signal, and comparing the resulting patterns across groups. Researchers then interpret the location or distribution of fluorescence in relation to gene expression, cellular changes, tissue development, or other study outcomes.
Researchers use these larvae when they need a visible reporter for processes occurring during animal development. Applications supported by the model include tracking gene expression, following cell lineage, examining tissue development, and investigating disease-related processes. Because imaging can be performed on living or fixed specimens, the approach supports both developmental observation and microscopy-based endpoint comparisons.
