Compared with non-lesioned skin, among infiltrating cells in the skin lesions of lichenified eczema, the numbers of IL-13-expressing T cells [45], IL-4-expressing T cells (CD4+ cells), INF-γ-expressing T cells (CD4+ cells and CD8+ cells), and DCs [79] are significantly increased. Here, CD4 is linked to Eczematoid dermatitis.
