Skin biopsy specimens from Asian children with atopic dermatitis express significantly higher levels of T helper Th17‐ and Th22‐related cytokines (especially interleukin (IL)‐17A, IL‐19, and IL‐22) and IL‐17/IL‐22 than found in skin biopsy specimens from European American children.37 Here, IL17A is linked to atopic eczema.
