In the article “Engagement of the GABA to KCC2 Signaling Pathway Contributes to the Analgesic Effects of A3AR Agonists in Neuropathic Pain” by Amanda Ford, Annie Castonguay, Martin Cottet, Joshua W. Little, Zhoumou Chen, Ashley M. Symons-Liguori, Timothy Doyle, Terrance M. Egan, Todd W. Vanderah, Yves De Konnick, Dilip K. Tosh, Kenneth A. Jacobson, and Daniela Salvemini, which appeared on pages 6057–6067 of the April 15, 2015 issue, the authors regret to inform the readers of an error in Figure 4, where the representative Western blot panels in A and B were incorrectly labeled: the ipsilateral and contralateral assignments were incorrect. This error does not affect any of the conclusions or interpretations in the paper. The correct assignments are shown in Figure 4 below.
