Curcumin Protects Against Collagen-induced Arthritis Via Suppression of BAFF Production
Overview
Affiliations
Purpose: The aim of the present study was to evaluate whether the anti-Rheumatoid arthritis (RA) effect of curcumin is associated with the regulation of B cell-activating factor belonging to the TNF family (BAFF) production.
Methods: Collagen-induced arthritis (CIA) was induced in DBA/1 J mice by immunization with bovine type II collagen. To investigate the anti-arthritic effect of curcumin in the CIA model, mice were injected intraperitoneally with curcumin (50 mg/kg) on every other day either from day 1 or from day 28 after the first immunization. The clinical severity of arthritis was monitored. BAFF, interleukin-6 (IL-6) and interferon-γ (IFNγ) production in serum were measured. Furthermore, the effect of curcumin on IFNγ-induced BAFF expression and transcriptional activation in B lymphocytes was determined by qPCR, Western Blot, and luciferase assay. Finally, IFNγ related signal transducers and activators of transcription 1 (STAT1) signaling in B lymphocytes were studied using Western Blot.
Results: Curcumin dramatically attenuated the progression and severity of CIA in DBA/1 J mice, accompanied with decrease of BAFF production in serum and spleen cells as well as decrease of serum IFNγ and IL-6. Treatment of B lymphocytes with curcumin suppressed IFNγ-induced BAFF expression, STAT1 phosphorylation and nuclear translocation, suggesting that curcumin may repress IFNγ-induced BAFF expression via negatively interfering with STAT1 signaling.
Conclusion: The results of the present study suggest that suppression of BAFF production may be a novel mechanism by which curcumin improves RA.
