Fig. 2. Expression of CD47 in various T cell subtypes. (A) FACS analysis of expression of CD47 in T cells, CD4⁺ T cells, and CD8⁺ T cells. All CD4⁺ T cells and CD8⁺ T cells expressed CD47. (B) FACS analysis of CD47 expression in CD3⁺CD4⁺CD25⁺ T cells and CD3⁺CD4⁺CD25⁺Foxp3⁺ T cells. Most CD4⁺CD25⁺Foxp3⁺ Treg cells expressed CD47. Treg, regulatory T; AD, atopic dermatitis.
