Glial Inx3 delineating the protocerebral bridge.


Glial Inx3 delineating the protocerebral bridge.

Defined areas of brain neuropil are surrounded by glia expressing Innexins 2, 3 and Ogre. The image shows the posterior brain of a 1-3 day old female of genotype nrv2GAL4 / UAS-mCD8::GFP.L. The nrv2GAL4 driver line ( Sun et al., 1999) expresses GFP (green) strongly in glial cells. Inx3 (blue) was detected using anti-Inx3 rabbit polyclonal antibody. A, GFP alone. B, Inx3 alone. C, Merged image. Pb – protocerebral bridge. CG – processes of the cortex glia.
