ABSTRACT

Objective:

To investigate the mechanisms of paeoniflorin on T cells in Bovine Collagen-induced arthritis ( CIA) model.

Methods:

CIA were established with Bovine Type Ⅱ collagen in DBA/1J mice.From day 21,after divided into two groups at random,mice were treated with PBS or paeoniflorin and recorded arthritis scores every day;the inflammation of CIA was evaluated with HE staining of the joints;the proliferations of splenocytes and CD4+T cells stimulated either by CD3 antibody and CD28 antibody or CII were examined by 3 H-TdR incorporation assay;the ratio of Th1 and Th17 subsets in CD4+T cells were examined by flow cytometry;the concentration of IFN-γand IL-17 in the culture supernatants of splenocytes were detected by ELISA.

Results:

The administration of paeoniflorin alleviated the symptoms( P<0.05) and inhibited the inflammation response of CIA;paeoniflorin not only inhibited the pro-liferation of CD3/28 antibodies-stimulated splenocytes and CD4+T cells(P<0.05),but also inhibited the proliferation of CII-specific splenocytes and CII-specific CD4+T cells(P<0.01);paeoniflorin modulated the ratio of Th1 and Th17 subsets(P<0.01);paeoniflorin reduced the levels of IFN-γand IL-17 in the culture supernatant of splenocytes ( P<0.05 ).

Conclusion:

Paeoniflorin may alleviates clinical symptoms of CIA via inhibiting pathogenic T cell proliferation, balancing inflammatory T cell subsets and reducing pro-inflammatory cytokines.
