After publication of this article, we noted that the IgM–/– mouse strain used in experiments reported in Fig. 4j and Extended data Fig. 7l was incorrectly referenced in the Methods. The IgM–/– mouse strain purchased from The Jackson Laboratory and used in our study was 002288 (i.e., IgM–/– mice lacking mature B cells), and not 003751 as mistakenly published in the original version of the article. This has been corrected in the HTML and PDF versions of the article.
