Abstract

Cedrela odorata L. is a native plant of the Amazon region. The bark is used in folk remedies for the treatment of diarrhea, vomiting, fever and inflammation. Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease accompanied by itching. It is a complex disease involving environmental factors and genetic factors. In the present study, the anti‑inflammatory and anti‑allergic effects of C. odorata L. methanol extract (COEE) on tumor necrosis factor (TNF)‑α and interferon (IFN)‑γ‑stimulated HaCaT keratinocyte cells were investigated. ELISA and RT‑PCR analysis revealed that the extract had anti‑inflammatory effects, and reduced the interleukin (IL)‑6 and IL‑8 levels of the HaCaT cells. In addition, COEE exhibited anti‑allergic effects, comprising a reduction in the thymus and activation‑regulated chemokine and macrophage‑derived chemokine levels. In addition, pathway analysis and comparison with Bay11‑7082 indicated that these effects are due to the inhibition of nuclear factor (NF)‑κB in TNF‑α/IFN‑γ‑induced HaCaT cells. Therefore, the results of the present study suggest that COEE has anti‑inflammatory and anti‑allergic properties in TNF‑α and IFN‑γ‑stimulated HaCaT cells, which are associated with the inhibition of pro‑inflammatory cytokines and chemokines via the NF‑κB pathway.
