An imiquimod (IMQ) induced wild type (WT) mouse can mimic some features of psoriasis, such as thickened skin, abnormal keratinocyte-related proteins, infiltration of inflammatory cells and pro-inflammatory cytokines. This model is a prevalent model that is widely used in the study of psoriasis. However, skin inflammation decreases during the eighth day when IMQ is given to WT mice, which may result in false results when evaluating the pharmacodynamics effects of a drug. To extend the timeliness and inherit the advantages of this model, we applied IMQ to the skin of 8-week-old homozygous K14-VEGF mice to investigate whether IMQ can prolong mice ear inflammation. In our experiments, we found that, compared to the IMQ induced WT mice model, the IMQ induced K14-VEGF mice have serious skin inflammation, even on the fourteenth day. We also evaluated the stability of skin inflammation at days 8, 10, and 13, and the inflammatory situation remained stable in the skin. This research intends to improve the existing model, and we hypothesize that the IMQ induced K14-VEGF mouse will become a practical mouse model in psoriasis research.
