28 day old Bace2045/Bace5243 and Bace2045/Df(2L)Exel7038 flies show degeneration of the lamina, with vacuolisation in the lamina cortex. The flies also show vacuoles in the lamina neuropil and central brain. 3 week old Bace2045/Bace5243 flies show gaps in the rows of glia in the subretinal layer and most of the epithelial glia are lost.
Bace2045/Df(2L)Exel7038 is rescued by Scer\GAL4elav.PU/BaceUAS.cCSa
Bace2045/Df(2L)Exel7038 is rescued by Scer\GAL4Bace.5.4/BaceUAS.cCSa
Expression of BaceScer\UAS.cCSa under the control of Scer\GAL4elav.PU significantly reduces the vacuolisation of the lamina neuropil and cortex which is seen in 28 day old Bace2045/Df(2L)Exel7038 flies.
Expression of BaceScer\UAS.cCSa under the control of Scer\GAL4Bace.5.4 completely rescues the vacuolisation of the lamina neuropil and cortex which is seen in 28 day old Bace2045/Df(2L)Exel7038 flies.
