Therefore, we measured the mRNA and protein expression of LCN2 in the different groups on the 10th day and found that the mRNA and protein expression were upregulated in IMQ-induced psoriasis-like skin lesions compared with those in the control group, whereas BZLF inhibited LCN2 mRNA and protein expression (Figures 7A, B). This evidence concerns the gene LCN2 and psoriasis.
