Figure S1. MDCs but not pDCs display CD83 in IMQ-treated BCCs, and perforin/granzyme B-containing T cells occur in lesions of allergic contact dermatitis but not IMQ-treated BCCs. Immunofluorescence triple labeling of IMQ-treated BCC lesions with anti-CD83 (FITC), anti-HLA-DR (APC), and (A) anti-CD123 (TRITC) or (B) anti-CD11c (PE) revealed mDCs, but not pDCs (arrows), as CD83⁺ mature DCs. Triple immunofluorescence labeling of (C and E) allergic contact dermatitis and (D and E) IMQ-treated BCCs with anti-CD3 (FITC), anti-CD8 (APC), and (C and D) antiperforin (TRITC) or (E and F) anti-granzyme B (FITC) antibodies revealed T cells of allergic contact dermatitis as perforin- and granzyme B-containing cells (C and E), whereas perforin and granzyme B expression in IMQ-treated BCC lesions was mainly observed on CD3^- cells (D and F, arrows). Four biopsies of patients with allergic contact dermatitis involved in a previous study were evaluated.
