IL4 and Psoriasiform dermatitis: However, there was no significant difference in the expression of anti‐inflammatory factors between psoriasiform dermatitis mice and control mice (IL‐10, cortex 0.995 ± 0.020 vs. 1.000 ± 0.012, t = 0.221, p > 0.05, hippocampus 1.007 ± 0.015 vs. 1.000 ± 0.027, t = 0.219, p > 0.05; IL‐4, cortex 1.023 ± 0.021 vs. 1.000 ± 0.022, t = 0.740, p > 0.05, hippocampus 1.053 ± 0.022 vs. 1.000 ± 0.028, t = 1.488, p > 0.05, Figure 5B).
