Correction to: Nature Medicine https://doi.org/10.1038/s41591-018-0290-5, published online 17 December 2018.

In the version of this article originally published, there was an error in the legend for Extended Data Fig. 7. The legend for panel f was originally: “f, FACS analysis of IL7R, CD62L and CD45RA expression on TRAC-1928ζ and TRAC-1XX CAR T cells at day 63 post CAR infusion (representative for at least n = 3 mice per group in one independent experiment).” The legend should have been: “f, FACS analysis of IL7R+, CD62L+ and CD45RA+ expression on TRAC-1928ζ and TRAC-1XX CAR T cells at day 63 post CAR infusion (representative for at least n = 3 mice per group in one independent experiment).” The error has been corrected in the HTML and PDF versions of this article.
