The garland cell nephrocytes of third instar larvae expressing snsdsRNA.Scer\UAS.WIZ under the control of Scer\GAL4sns.GCN have shape defects and are more loosely associated than normal.
The numbers of nephrocyte diaphragms in the garland cell nephrocytes of second instar larvae expressing snsdsRNA.Scer\UAS.WIZ under the control of Scer\GAL4sns.GCN is reduced compared to controls, although the NDs that do form appear normal by TEM analysis.
The surface of the garland cell nephrocytes of third instar larvae expressing snsdsRNA.Scer\UAS.WIZ under the control of Scer\GAL4sns.GCN is more uniform than that of control cells when analysed by SEM.
Garland cell nephrocytes from second instar larvae expressing snsdsRNA.Scer\UAS.WIZ under the control of Scer\GAL4sns.GCN show efficient uptake of dextran 10kD after co-incubation with both Cascade Blue dextran 10kD and fluorescein dextran 500kD for 5 minutes. However, these cells show a very poor uptake of dextran 500kD under these conditions compared to controls.
