In the article “Visual Impairment in the Absence of Dystroglycan” by Jakob S. Satz, Alisdair R. Philp, Huy Nguyen, Hajime Kusano, Jane Lee, Rolf Turk, Megan J. Riker, Jasmine Hernández, Robert M. Weiss, Michael G. Anderson, Robert F. Mullins, Steven A. Moore, Edwin M. Stone, and Kevin P. Campbell, which appeared on pages 13136–13146 of the October 21, 2009 issue, there was an error in Figure 7. The corrected figure and legend appear below.
Figure 7.
Localization of mGluR6 and Kir4.1. A–F, Sections of adult wild-type littermate (left column) and Nestin-CRE/DG-null (right column) retina labeled with antibodies to mGluR6 (A, B) and Kir4.1 (C–F). G, H, Sections of wild-type littermate (left column) and GFAP-CRE/DG-null (right column) retina labeled with an antibody to Kir4.1. Note the loss of Kir4.1 localization in perivascular glial endfeet (normal marked by asterisks in E, G) and the loss of Kir4.1 clustering in Müller glial endfeet at the inner limiting membrane (arrows). Müller glial processes (arrow heads) retained Kir4.1 expression. The sections were counterstained with propidium iodide. E, F, High-magnification views of the boxed regions in C and D, respectively. GCL, Ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer; ONL, outer nuclear layer.
