Dietary flavanones and citrus fruits influence cytokines and thyroid transcription factor-1 in an HDM-induced chronic asthma murine model

The effects of hesperetin plus naringenin, orange juice and grapefruit juice on mRNA expression of TNF-α, TGF-β1 and TTF-1 in a house dust mite (HDM)-induced asthma animal model were investigated. Interventional mice exposed to HDM for 6 weeks received hesperetin plus naringenin, orange plus grapefruit juice, orange juice, grapefruit juice or water during the last 4 weeks, whereas non-asthmatic control mice consumed water. Lung tissue TNF-α and TGF-β1 expressions in supplemented groups were significantly reduced (p
