Badanie transportu białek błonowych w komórkach fotoreceptorowych Drosophila przy użyciu białek znakowanych eGFP

Overview

This study presents non-invasive methods for localizing photoreceptor membrane proteins and assessing retinal degeneration in the Drosophila compound eye using eGFP fluorescence. Employing GFP-tagged proteins, such as the ion channel TRPL GFP, allows for the monitoring of photoreceptor transport and degeneration, offering insights into hereditary blindness in humans.
