TOH-containing emulgel reduced CD4⁺ T-cell infiltration into psoriatic mice treated with TOH-containing emulgel. (a) Representative images of immunohistochemical staining of CD4⁺ cells in the dorsal skin of the mice in all the groups. Representative images of skin sections were taken at ×10 and ×40 magnification (scale bars: 100 μm and 50 μm, respectively). The CD4⁺ cells are indicated by a black arrow. (b) Quantification of CD4⁺ cells in all groups (n = 5). The data are presented as the means ± SD. Statistical significance was determined by one-way ANOVA. *p < 0.05, **p < 0.01, and ***p < 0.001.
