Gene Expression of CD70 and CD27 Is Increased in Alopecia Areata Lesions and Associated with Disease Severity and Activity

Figure 2

The relative expression of CD27 gene in patients with AA (n = 40) compared to HCs (n = 40). The relative CD27 gene expression in AA lesions ranged from 0.09 to 11.96 (mean 3.19 ± 3.65, median 1.58), while in non-lesional areas, it ranged from 0.0 to 1.68 (mean 0.25 ± 0.38, median 0.14). Wilcoxon signed rank test (p1) was used to compare the expression in AA lesions and non-lesional areas. Mann–Whitney test (p2) was used to compare the expression in AA lesions and HCs. Mann–Whitney test (p3) was used to compare the expression in non-lesional areas and HCs. Significant at . AA: alopecia areata; HCs: healthy controls; CD: cluster differentiation.
