title: Ameliorative effects of Artemisia argyi Folium extract on 2,4‑dinitrochlorobenzene‑induced atopic dermatitis‑like lesions in BALB/c mice.
abstract: Artemisia argyi Folium has been used to treat skin diseases, including eczema and dermatitis, in South Korean medicine. The present study investigated the curative effects of Artemisia argyi Folium extract (AAFE) on 2,4‑dinitrochlorobenzene (DNCB)‑induced atopic dermatitis (AD)‑like skin lesions in a BALB/c mouse model. Briefly, the dorsal skin of the BALB/c mice was sensitized three times with DNCB, whereas the ears were challenged twice. Repeated treatment with DNCB induced AD‑like lesions. The effects of AAFE on AD‑like lesions were evaluated by clinical observation, histopathological analysis, immunohistochemistry and enzyme‑linked immunosorbent assay. In addition, reverse transcription‑polymerase chain reaction and western blotting were performed. Treatment with AAFE reduced AD‑like lesions, as determined by clinical observation, histopathological analysis, and detection of the serum levels of histamine, immunoglobulin E and cytokines. With regards to its mechanism of action, AAFE inhibited the phosphorylation of Lck/yes‑related novel tyrosine kinase (Lyn), spleen tyrosine kinase (Syk), mitogen‑activated protein kinases (MAPKs), phosphoinositide 3‑kinase (PI3K)/Akt and IκBα, which have essential roles in the production of various cytokines in lymph nodes. The suppressive activity of AAFE may be due to the inhibition of a series of immunopathological events, including the release of proinflammatory cytokines. The results of the present study strongly suggest that AAFE exerts an anti‑AD effect by inhibiting the Lyn, Syk, MAPKs, PI3K/Akt and IκBα pathways. Therefore, AAFE may be considered an effective herbal remedy for the treatment of AD.
