Correction to: Nature Immunology, published online 18 February 2019

In the version of the article initially published, the text “This work was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – SCHE 670 2-1 – no. 387835892 (to A.S.) and TRR241 – no. 375876048 (to A.S., C.R.)” was missing from the Acknowledgments section. This notice serves to correct this omission.
