Figure 3: DLGS97 does not change the size of the GLURIIB receptor fields but increases the size of GLURIIA receptor fields.

Confocal images of synaptic boutons of WT and dlg mutants labeled with antibodies against GLURIIA (A) or GLURIIB (B) in green and GLURIII (A) or the active zone protein Bruchpilot (B) in red. (C) Quantification of the size of the clusters for the three GLURs. dlgS97 mutants display increased size of GLURIII and GLURIIA receptor fields. None of the mutants display changes in the size of GLURIIB-fields. Columns represent the average of 5 or 6 different larvae. *p < 0.05, **p < 0.01 respect to the WT.
