(a) Expression levels of activating receptors on gated CD3– CD56+ NK cell from PB and SF samples of patients with chronic arthritis (n = 9). Fluorescence intensity is expressed as geometric mean (MFI). For NKG2C the fluorescence intensity was calculated on NKG2C-expressing NK cells. For NKG2D, NKp46, NKp44 and NKp30, the fluorescence intensity was calculated on all NK cells. Lines connect paired samples from each patient. Statistically significant differences on paired comparison between PB and SF NK cells; NKp46 P = 0·008, NKp44 P = 0·008. (b) Expression profile of NKp44/CD56 on gated CD3– CD56+ NK cells from one healthy donor PB and one patient PB and SF. (c) NKp44 expression levels portrayed as geometric mean of fluorescence intensity on PB NK-cell subsets (healthy donors n = 9, and arthritis patients n = 9) and on all SF NK cells (n = 9). CD56bright/dim subsets were defined according to the CD56 staining pattern on CD3– CD56+ lymphocytes in blood.
