Figure 2.

The effect of IL-23 on the expression of CD69 in MAIT cells from OLP patients in the absence or presence of PMA and ionomycin. (a) The gating strategy for CD69 staining in T cells, MAIT cells, and CD8⁺MAIT cells is shown by representative images in different groups and (b–d) Histograms of CD69 expression in T cells, MAIT cells, and CD8⁺MAIT cells. Normally distributed variables are presented as mean ± SD, while non-normally distributed data are presented as mean ± IQR and labeled by “#”. P < 0.05 was defined as statistically significant.

MAIT, mucosal-associated invariant T; OLP, oral lichen planus; PMA, phorbol myristate acetate; FMO, fluorescence minus one; SD, standard deviation; IQR, interquartile range.
