In the article “Itk Signals Promote Neuroinflammation by Regulating CD4+ T-Cell Activation and Trafficking” by Arun K. Kannan, Do-Geun Kim, Avery August, and Margaret S. Bynoe, which appeared on pages 221–233 of the January 7, 2015 issue, there was an error in Figure 1E. The values on the y-axis of Figure 1E, day 31, should be ×106, not ×103, as was indicated in the original published article. This change does not affect the interpretation of the results. Figure 1 has been corrected in the on-line PDF version, and a corrected version is displayed below.
