The Chief Editor is correcting this article at the request of the corresponding author, Christian Engwerda. An investigation by QIMR Berghofer Medical Research Institute found that the original Figs. 7e, 7h (upper panel) and 8a and Extended Data Fig. 5b (EO771 data only) were based on experiments for which no evidence of their conduct or primary data could be confirmed. As such, the data from the underlying experiments are believed to have been fabricated or are unreliable, respectively. The four panels have been removed from Figs. 7 and 8 and Extended Data Fig. 5 (see Supplementary Information for a list of edits and original article for comparison). The major finding of the paper that NKG7 regulates cytotoxic granule exocytosis and inflammation remains unaffected. No concerns have been raised regarding other data in the paper.
