Localization of glutamine synthase in the retina. Paraffin sections of mouse (A, B), rat (C, D, G-I), or human (E, F) retina fixed in 4% paraformaldehyde were reacted with anti-glutamine synthase (red fluorescence staining in B, D, G, I, and brown immuno-peroxidase reaction [using ABC kit and visualization with DAB product in F]. Nuclei in some immunofluorescence experiments (A-D) were stained with DAPI (shown in cyan), and with nuclear fast red in E and F. On inspection at low magnification, anti- glutamine synthase reacted with a single population of cells extending from the ganglion cell layer (GCL) through the inner nuclear layer (INL). No signal was detected in controls either pre-incubated with 100ug/ml of the immunizing peptide (A) or with pre-immune serum (C, E). The pattern of staining observed in all experiments is typicals. This finding was confirmed by co-localization (indicated by yellow in I) of glutamine synthase (red in G) with antoher marker of glutamine synthase (green in H).

Glutamine synthase is part of the glutamine synthetase family. Ammonia incorporation in animals occurs through the actions of glutamate dehydrogenase and glutamine synthase. Glutamate plays the central role in mammalian nitrogen flow, serving as both a nitrogen donor and nitrogen acceptor.
Neurovascular crosstalk between interneurons and capillaries is required for vision.
