MKI67 and psoriasis: IHC analysis revealed that the expression levels of CD3 and Ki67 in the FZHFZY group and the Cal group were significantly lower as compared to those in the IMQ group (P < 0.001)(Figures 3E–H), the results suggest that the IMQ-induced psoriasis mice exhibited T-cell infiltration and abnormal keratinocyte activity, and treatment with FZHFZY inhibited inflammatory cell infiltration and keratinocyte proliferation.
