Understanding the function of Langerhans cells (LC) in vivo has been complicated by conflicting results from LC-deficient mice. HuLangerin-DTA mice constitutively lack LC and develop exaggerated contact-hypersensitivity (CHS) responses. MuLangerin-DTR mice allow for the inducible elimination of LC and Langerin+ dermal DC (dDC) after administration of diphtheria toxin (DT) which results in reduced CHS. When Langerin+ dDC have partially repopulated the skin but LC are still absent, CHS returns to normal. Thus, LC appear to be suppressive in huLangerin-DTA and redundant in muLangerin-DTR. To determine whether inducible vs. constitutive LC ablation explains these results, we engineered huLangerin-DTR mice in which DT ablates LC without affecting Langerin+ dDC. The inducible ablation of LC in huLangerin-DTR mice resulted in increased CHS. Thus, LC-mediated suppression does not require their absence during ontogeny or during the steady state and is consistent with a model in which LC actively suppress antigen specific CHS responses.
