Abstract: BACKGROUND: Two isoforms of interleukin-1, interleukin-1α and interleukin-1β, which have similar bioactivity, have been shown to have significant effects on bone metabolism and have been shown to induce differentiation of osteoblasts or osteoclasts.
OBJECTIVE: To summarize the relationship between interleukin 1 and osteoblasts or osteoclasts, and to understand the mechanism of interleukin 1 in bone metabolism, so as to provide theoretical reference for new osteogenic programs.
METHODS: CNKI and PubMed were searched for articles related to the mechanism of interleukin-1 in osteoblasts and osteoclasts. A total of 74 articles were included for review analysis. 
RESULTS AND CONCLUSION: Interleukin 1, as a multifunctional cytokine in vivo, has a profound effect on both osteogenic and osteoclastic metabolism. (1) Interleukin 1 is closely related to the differentiation, activation and survival of osteoclasts. It can not only exert osteoclast effect directly through RANKL/RANK, but also reduce the production of osteoprotectin and indirectly stimulate osteoclast formation by upregulation of prostagland E2 and macrophage colony stimulating factor. In addition, the multinucleated maturation of osteoclasts was also closely related to interleukin 1. (2) It has been found that interleukin 1β not only affects the differentiation of osteoblasts, but also indirectly regulates osteogenic metabolism by affecting osteoblast-related proteins. (3) Recent studies have shown that interleukin 1β can regulate the structure of blood clots and thus affect early bone healing, which provides a useful reference for our study of interleukin 1β. (4) Therefore, this review is expected to further understand the specific mechanism of interleukin 1 involved in bone metabolism and provide theoretical reference for good osteogenesis strategies.
