Dysregulation and abnormal expression of inflammatory mediators by keratinocytes promote the pathogenesis of the skin inflammation such as allergic contact dermatitis (ACD). High-mobility group box 1 (HMGB1) protein, a prototypical damage-associated molecular pattern (DAMP), that is expressed in the nucleus but released extracellularly upon inflammation has gained attention as an accelerator for skin inflammation. However, in vivo role of HMGB1 in ACD and other skin disorders remains to be elusive. In this study, we generated conditional knockout mice in which HMGB1 is deleted in keratinocytes and examined its role in skin inflammation models including 2,4-dinitrofluorobenezene (DNFB)-induced ACD. |
