Natural killer (NK) cells expressing Ki67 are increased in systemic lupus erythematosus (SLE). (a) Scatter‐plot of the frequency of Ki67+ NK cells in the peripheral blood of SLE patients (n = 174, median = 16·3) and healthy donors (HD) (n = 99, median = 7·6). Dashed line indicates 2 standard deviations (s.d.) from HD mean (16·74%) Middle bar denotes median; surrounding bars denote first and second interquartile ranges. (b) Representative examples of Ki67 expression on NK cells from SLE patient and HD. (c) Scatter‐plot of the percentage of the indicated NK receptors (NKR) expressed on NK cells SLE (n = 15 or 27) and HD (n = 5 or 10). Middle bar denotes median; surrounding bars denote first and second interquartile range. Statistical analysis performed using the Mann–Whitney U‐test.
