Abstract

The present study aimed to investigate the molecular mechanisms underlying the effects of total glucosides of peony (TGP) in the treatment of Sjögren's syndrome (SS). A total of 40 mice with SS were evenly assigned into four groups, including: Control group; TGP group, receiving 1 mg TGP daily; hydroxychloroquine (HCQ) group, receiving 0.25 mg HCQ daily; and a combined group, receiving 1 mg TGP and 0.25 mg HCQ daily. After 8 weeks, quantitative polymerase chain reaction and an enzyme‑linked immunosorbent assay were used to detect the levels of interferon‑γ (IFN‑γ), interleukin‑4 (IL‑4), Fas and FasL in each group of mice. In addition, immunohistochemical analysis was used to determine the expression levels of IFN‑γ and IL‑4. IFN‑γ, IL‑4, Fas and FasL levels were significantly increased in the control group compared with the other three groups (P<0.05). Furthermore, the expression levels of these factors were reduced in the combined group in comparison with the HCQ group (P<0.05). The ratios of IFN‑γ to IL‑4 were decreased in the TGP and combined groups compared with the control group (P<0.05). The present results indicate that TGP ameliorates SS by affecting the Th1/Th2 cytokine balance and decreasing the expression levels of IFN‑γ, IL‑4, Fas and FasL. Therefore, TGP may represent a potential novel therapeutic agent for the treatment of SS.
