Nanometer Resolution Imaging of Axonal Transport Defects in Drosophila Alzheimer’s Models
This study investigates axonal transport defects in Drosophila models of Alzheimer’s disease using advanced nanometer resolution detection techniques. Employing fluorescence imaging and multi-peak fitting, we analyze brain segmental nerves to identify and quantify transport abnormalities. The system verification involved the use of fluorescent beads, allowing precise trajectory recovery of APP-YFP vesicles. Our findings utilize a Nikon Eclipse TE2000-U inverted microscope with a 100×/1.40 NA oil objective, supported by a LabVIEW-controlled piezo stage for enhanced pattern recognition and analysis.
