Abstract

6‑Shogaol (SHO) and 6‑gingerol (GIN), naturally derived compounds of ginger (Zingiber officinale Roscoe), have been found to have anti‑allergic effects on dermatitis‑like skin lesions and rhinitis. Although SHO and GIN have demonstrated a potential in various inflammatory diseases, their efficacy and mechanism in asthma have not been largely examined. Therefore, the present study demonstrated the anti‑asthmatic effects of SHO and GIN on the T‑helper (Th) 2 cell‑mediated allergic response pathway in an ovalbumin (OVA)‑induced asthma mouse model. The asthma mouse model was established with an intraperitoneal (i.p.) injection of 50 µg OVA and 1 mg aluminum hydroxide with or without an i.p. injection of SHO and GIN (10 mg/kg) before treatment with OVA. In addition, the current study assessed mast cell degranulation in antigen‑stimulated RBL‑2H3 cells under different treatment conditions (SHO or GIN at 0, 10, 25, 50 and 100 nM) and determined the mRNA and protein levels of anti‑oxidative enzymes [superoxide dismutase (SOD)1, SOD2, glutathione peroxidase‑1/2, catalase] in lung tissues. SHO and GIN inhibited eosinophilia in the bronchoalveolar lavage fluids and H&E‑stained lung tissues. Both factors also decreased mucus production in periodic acid‑Schiff‑stained lung tissues and the levels of Th2 cytokines in these tissues. GIN attenuated oxidative stress by upregulating the expression levels of anti‑oxidative proteins. In an in vitro experiment, the degranulation of RBL‑2H3 rat mast cells was significantly decreased. It was found that SHO and GIN effectively suppressed the allergic response in the mouse model by inhibiting eosinophilia and Th2 cytokine production. Collectively, it was suggested that SHO can inhibit lung inflammation by attenuating the Th2 cell‑mediated allergic response signals, and that GIN can inhibit lung inflammation and epithelial cell remodeling by repressing oxidative stress. Therefore, SHO and GIN could be used therapeutically for allergic and eosinophilic asthma.
