Fig. 4. Increased expression of CD47 in human Treg cells from AD patients. (A) All CD4⁺CD25⁺Foxp3⁺ Treg cells expressed CD47 in humans, a result similar to that for mice. (B) The expression level of CD47 was higher in Treg cells from AD patients than in those from healthy controls. (C) The severity of AD correlated with the expression of CD47 (Pearson correlation r=0.84, p=0.018). AD, atopic dermatitis; Treg, regulatory T.
