Correction to: Nature Biotechnology https://doi.org/10.1038/s41587-020-0487-2, published online 7 April 2020.

In the version of this article initially published, Jürgen Kuball was quoted as saying that monoclonal antibody and CAR-T cell therapies rely “on the clonal nature of a certain T cell receptor.” This should have read “on the clonal nature of a certain receptor.” The article also said that γδ T cells are almost entirely CD8+; this characterization has been deleted. Finally, the phrase “only cells with intact receptors retain antitumor activity” was linked to https://cancerimmunolres.aacrjournals.org/content/early/2020/02/04/2326-6066.CIR-19-0513.long; the link has been changed to https://doi.org/10.1182/blood-2012-05-432427. The errors have been corrected in the HTML and PDF versions of the article.
