(A) Construct for triple transgenic mice expressing ovalbumin (Ova) driven by the Keratin-5 promoter in a tetracycline inducible fashion. Mice were further crossed to the D011.10 T cell receptor (TCR)-transgenic strain to generate the K5/TGO/DO11 model. (B) Representative flow cytometric plots and (C) quantification of DC profiling in skin and skin draining lymph nodes (SDLNs) during the first 10 days after induction of antigen expression. (D) Representative flow cytometric plots and (E) quantification of CD103+ DDCs and (F) Langerhans cells (LCs) in skin and SDLNs. One representative experiment of four is shown. Data are mean ± s.e.m. ns = no significant difference. *P<0.05, **P<0.01 ***P<0.001, One-way ANOVA, day 0 vs, other time points (B, D, E).
