The Increased Ratio of Blood CD56^bright NK to CD56^dim NK Is a Distinguishing Feature of Primary Sjögren’s Syndrome

Figure 1

Comparison of percentage and counts of peripheral blood NK cells and CD56 NK cell subsets between pSS patients and HC. (a) The gating strategy is shown for the analysis of NK population. (b) The percentage of peripheral blood NK cells and their constituent CD56 subsets. (c) The absolute number of peripheral blood NK cells and their constituent CD56 NK cell subsets. (d) The ratio of CD56^bright NK/CD56^dim NK in autoimmune diseases. The horizontal line represents the mean. Definitions of abbreviations: HC = healthy controls; pSS = primary Sjögren’s syndrome.
