Abstract: BACKGROUND:  Most studies have shown that MAPK, nuclear factor κB, and Wnt signaling pathways are the major signaling pathways associated with osteoarthritis.
OBJECTIVE: To review the related literature at home and abroad, and to summarize the mechanism of inflammatory cytokines and related signaling pathways in osteoarthritis, in order to further understand the pathogenesis of osteoarthritis.
METHODS: CNKI, WanFang, VIP, MEDLINE, and PubMed databases were searched for relevant articles addressing inflammatory cytokines and related signaling pathways in osteoarthritis using the keywords of “osteoarthritis, inflammatory cytokine, signal path, pathogenesis, interleukin, BMP, treatment ” in Chinese and English, respectively. After reading the titles and abstracts, 55 articles were included according to the inclusion and exclusion criteria.
RESULTS AND CONCLUSION: Up to now, the mechanism of osteoarthritis is not clear. Previous studies have shown that inflammation and inflammatory cytokines play an important role in the occurrence and development of osteoarthritis. Strengthening the research on inflammatory cytokines may improve the therapeutic potential of osteoarthritis. Among these cytokines, interleukin-1β is considered to be the main inducer of osteoarthritis, which plays a key role in cartilage degradation and bone regeneration. Therefore, inhibiting the expression of interleukin-1β and inflammatory mediators induced by interleukin-1β may provide a promising method for the treatment of osteoarthritis. The development of osteoarthritis may involve the correlation and interaction between many cytokines and different signaling pathways, but the relationship between inflammatory cytokines and signaling pathways has not yet been clearly clarified, and the mechanism of changes between their molecules is still unclear. A full understanding of these signaling pathways will help us to find a more reliable treatment for osteoarthritis.
