Petunidin suppresses Hashimoto’s thyroiditis by regulating Th1/Th17 homeostasis and oxidative stress
Hashimoto’s thyroiditis (HT) is a prevalent autoimmune thyroid disease, necessitating further research to identify effective treatment strategies. Two key pathophysiological factors of HT are inflammation and oxidative stress. Petunidin (PET) is an anthocyanin with anti-inflammatory and antioxidant properties. This study aimed to investigate the effect and mechanism of PET on HT. C57BL/6N mice were injected with thyroglobulin emulsified with adjuvant to establish the HT animal model. Our results showed that PET administration decreased the concentrations of TPOAb, TgAb, T3, T4, IgG, IgA and IgM in HT mice, accompanied by significant alterations in follicle shape and increased lymphocyte infiltrations. Additionally, the apoptosis rate, ROS level, MDA content, CD4+ level, IFN-γ and IL-17A levels, as well as the concentrations of IFN-γ and IL-17, were elevated in HT mice and reduced by PET treatment. Furthermore, HT patients exhibited higher levels of NOX4 and PKM2, which were positively correlated with TPOAb, IFN-γ, and IL-17 concentrations. In HT mice, PET therapy decreased the expression of PKM2 and NOX4 proteins. In summary, PET can improve thyroid dysfunction by suppressing apoptosis, oxidative stress and Th1/Th17 differentiation through regulation of the NOX4/PKM2 axis in HT mice, suggesting its promising potential for HT intervention.
