To access the data, click or select the words “Appendix 4.” A: Retina immunolabeled for GLUT1. GLUT1-IR is strong in the elm, ONL, OPL, INL, IPL and some GCL. GLUT1-IR is weak to moderate in ISs. B: Retinas double labeled for GLUT1 and GS show colocalization in the elm and Mef/NFL. C: High magnification confocal image of a retina immunolabeled for GLUT1. D: Retina double labeled for GLUT1 and VGLUT1 show colocalization in the OPL and IPL. E: Retina immunolabeled for GLUT3. GLUT3-IR is strong to intense in the OPL and IPL. F: Retinas double labeled for GLUT3 and VGLUT1 show strong GLUT3-IR in glutamatergic synapses. For A-B and E, scale bar = 40 µm. For C-D and F, scale bar = 20 µm.
