| abstractText | MC903 skin inflammation model is one of well-characterized murine models of atopic dermatitis and driven by TSLP-mediated type 2 inflammation. Since it can be prepared simply by repetitive applications of MC903 and shows consistent clinical results, this model has been widely used. However, in contrast to human atopic dermatitis which is chronic and closely related to TH2 cells, MC903 induces inflammations temporarily and even in the absence of T cells. Here, we modified the MC903 treatment schedule and developed a chronic MC903-induced skin inflammation model. Mice were sensitized with a high dose of MC903 and challenged with a low dose of MC903. Prior to challenge, mice were allowed to recover completely from the inflammation which occurred during the sensitization. The challenge of MC903 induced skin swelling and type 2 inflammations more rapidly, which was dependent on CD4(+) T cells and IL-33. We expect that our mouse model will be beneficial for studying the late course of atopic dermatitis. |
