Figure 4: NTP treatment can block the accumulation of immune cells in DNCB-induced AD-like skin lesions.

(a) A schematic diagram for the whole procedure of the in vivo experiments. (b) The morphological changes of mice at the end of the animal experiments. (c) The results of hematoxylin and eosin (H&E) staining. The pictures are representative of each group of mice (n = 5). (d,e) The results of toluidine blue staining and immunohistochemistry against eosinophil peroxidase (EPX). The Figures are representative of each group of mice (n = 5). The total number of each cell type in a picture taken at 400 × magnification were optically counted and averaged for each mouse using 5 randomly selected pictures, *p < 0.05. Scale bar: 100 μm.
