Abstract EN
Rheumatoid arthritis (RA) is a serious autoimmune disease caused by chronic inflammation of connective tissues.
The basic principle of RA treatment is aimed to reduce joint inflammation.
Our previous studies demonstrated that salmon cartilage proteoglycan (PG) suppresses excess inflammation in different mouse inflammatory diseases.
In this study, we investigated the prophylactic effect of PG on the progression of RA using an experimental mouse model, collagen-induced arthritis (CIA).
Clinical and histological severity of CIA was attenuated by daily oral administration of PG.
In the joints of PG-administered mice, infiltration of macrophages and neutrophils and also osteoclast accumulation were limited.
In comparison to nonadministered mice, anti-collagen antibodies in the sera of PG-administered mice did not alter.
On the other hand, local expression of interleukin-17A (IL-17A), IL-6, IL-1β, interferon-γ (IFN-γ), C-C chemokine ligand 2 (CCL2), C-X-C chemokine ligand 1 (CXCL1), and CXCL2 in the joints of PG-administered mice decreased.
Moreover, in the response of type II collagen- (CII-) restimulation ex vivo, IL-17A and IFN-γ production by splenocytes from PG-administered mice was less than that of control mice.
These data suggested that daily ingested PG attenuated CIA pathogenesis by modulating immune response of splenocytes to CII stimulation and local production inflammatory cytokines and chemokines in the joints.
