Abstract

Rhododendron album Blume (RA) has traditionally been used as an herbal medicine and is considered to have anti‑inflammatory properties. It is a well‑known medicine for treatment of allergic or atopic diseases. In the present study, the biological effects of an RA methanol extract (RAME) on inflammation were investigated in tumor necrosis factor‑α (TNF‑α)/interferon‑γ (IFN‑γ)‑stimulated human keratinocytes. The present study aimed to investigate the potential mechanisms by which RAME inhibited TNF‑α/IFN‑γ‑induced expression of chemokines [thymus‑ and activation-regulated chemokine (TARC) and macrophage‑derived chemokine (MDC)] and cytokines [interleukin (IL)‑6 and IL‑8] through the nuclear factor‑κB (NF‑κB) pathway in human keratinocytes. The effects of RAME treatment on cell viability were investigated in TNF‑α/IFN‑γ‑stimulated HaCaT cells. The expression of TARC, MDC, IL‑6 and IL‑8 was assessed using reverse transcription‑quantitative polymerase chain reaction analysis or ELISA, and its effect on the inhibitory mitogen-activated protein kinase pathway was also studied using western blot analysis. TNF‑α/IFN‑γ induced the expression of IL‑6, IL‑8, TARC and MDC in a dose‑dependent manner through NF‑κB and Janus kinase/signal transducers and activators of transcription (JAK/STAT) activation. Notably, treatment with RAME significantly suppressed TNF-α/IFN-γ-induced expression of IL‑6, IL‑8, TARC, and MDC. In addition, RAME treatment inhibited the activation of NF‑κB and the JAK/STAT pathway in TNF‑α/IFN‑γ‑induced HaCaT cells. These results suggest that RAME decreases the production of chemokines and pro‑inflammatory cytokines by suppressing the NF‑κB and the JAK/STAT pathways. Consequently, RAME may potentially be used for treatment of atopic dermatitis.
