In this article (Cancer Res 2016;76:2087–93), which appeared in the April 15, 2016, issue of Cancer Research (1), the sequence that was used to generate the TALEN was incorrect as reported in Fig. 1. The sequence that was used is located in exon 2 and not exon 1 as reported. Hence, “CD8PD-1Ex1” and “TRLPD-1Ex1” throughout the text, figures, and supplementary data should have been “CD8PD-1Ex2” and “TRLPD-1Ex2,” respectively. In addition, the correct name of the eighth author is Javier Herrero. The authors regret these errors.
