Application of Staphylococcus aureus extracellular vesicles (EV) to tape-stripped mouse skin induces atopic dermatitis-like inflammation. (A) Study protocol: application of different doses of S. aureus EV to tape-stripped mouse skin for 4 weeks (n = 5 per treatment group). (B) Skin histology [H&E staining; magnification, ×200 (upper panel) and ×400 (lower panel)]. Arrowheads identify eosinophils. (C) Histological analysis of epidermal thickness and the numbers of eosinophils and mast cells infiltrating the dermis. *P < 0.05; **P < 0.01; ***P < 0.001.
