Bottom Line: To date, no therapy has been found to satisfactorily treat SLE.Resveratrol also suppressed CD69 and CD71 expression on CD4+ T cells as well as CD4+ T cell proliferation, induced CD4+ T cell apoptosis, and decreased CD4 IFNγ+ Th1 cells and the ratio of Th1/Th2 cells in vitro.In vitro antibody production and proliferation of B cells were also inhibited.

ABSTRACT

Background: Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease characterized by the production of autoantibodies. To date, no therapy has been found to satisfactorily treat SLE. SIRT1 deficiency results in the development of an autoimmune syndrome in mice, including a high titer of anti-nuclear antibody in serum, immunoglobulin deposition in the kidney, and immune complex glomerulonephritis. Resveratrol is an activator of SIRT1 and possesses anti-inflammation and immune-regulatory properties.

Objective: To evaluate the preventative effects of resveratrol on a pristane-induced lupus animal model and assess its putative immune modulation effects.

Methods: BALB/c mice received a single intraperitoneal injection of 0.5 ml of pristane on day 1 and then various doses of resveratrol were given to the mice daily starting on day 2 and continuing for seven months. The autoantibodies in serum and supernatants were measured. Single cells isolated from spleen, isolated CD4+ T cells, and CD19+ B cells were cultured with or without resveratrol in vitro and assessed by flow cytometry.

Results: Resveratrol attenuated proteinuria, immunoglobuin depositon in kidney, and glomerulonephritis as well as IgG1 and IgG2a in serum in pristane-induced lupus mice. Resveratrol also suppressed CD69 and CD71 expression on CD4+ T cells as well as CD4+ T cell proliferation, induced CD4+ T cell apoptosis, and decreased CD4 IFNγ+ Th1 cells and the ratio of Th1/Th2 cells in vitro. In vitro antibody production and proliferation of B cells were also inhibited.

Conclusion: Resveratrol possesses protective effects in pristane-induced lupus mice and may represent a novel approach for the management of SLE.

Mentions: At the end of the observation period, IgG deposition in kidney of normal control mice was negative, 0−2+ in model control mice, and 0−1+ in mice from the resveratrol A and B groups (Fig. 2A-D, S2 Table). Moreover, the extent of IgG deposition in the kidney of resveratrol A and B mice was significantly lower than that in the model control mice (Z = 2.294; p = 0.022; and Z = 2.294; p = 0.022, respectively; S2 Table). However, the IgG deposition in mice from the resveratrol A and B groups was not significantly different (P>0.05). Similar results were observed for IgM deposition (Fig. 2E-H; S3 Table). Taken together, these results indicate that resveratrol attenuates pristane-induced nephritis.
