Correction to: Nature Immunology https://doi.org/10.1038/s41590-023-01559-1, published online 13 July 2023.

In the version of the article initially published, there was an error in Fig. 2f where the P value for “Quantity of IC-PE retained”, now reading 0.048, incorrectly appeared as 0.48. This has now been corrected in the HTML and PDF versions of the article.
