An OVA-induced asthma mouse model was used, and the mice were randomly divided into 4 groups: control group (PBS), asthma model group (OVA), γ-tocopherol group (γ-toc), and dexamethasone group (DEX). The results showed that γ-toc could reduce airway resistance, ameliorate lung function impairment, and inhibit inflammatory cell infiltration to a certain extent in asthmatic mice. Moreover, γ-toc could also decrease the expression levels of IL-4 and IL-13 in lung tissues, indicating that γ-toc could suppress asthma-related inflammatory reactions and exert anti-inflammatory effects. The results of this study provide a certain experimental basis for further research on the therapeutic effect of γ-toc on asthma.【Keywords】γ-tocopherol; asthma; IL-4; IL-13
