Sargassum horneri ethanol extracts (SHE) suppressed the infiltration of CD11c+ cells in skin and ear of 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis mice. Representative photographs of CD11c+ cells (arrowheads) infiltrated in skin (I–V) and ear (VI–X) are shown (A). The number of CD11c
cells per site in skin (B) and ear (C) are analyzed. Data are presented as the mean ± standard error. *p < 0.05 and **p < 0.005 indicate significant increase compared to naïve group. †p < 0.05 and ††p < 0.005 indicate significant decrease compared to DNCB group. Scale bars represent: 25 μm.
