  • Publication number: 20220409698
    Abstract: The present invention relates to a composition which is for preventing or treating bone diseases and includes CCR2 as an active ingredient. It was confirmed that a C—C chemokine receptor type 2 (CCR2) protein, a polynucleotide encoding the CCR2 protein, or a mesenchymal stem cell transduced with the CCR2 according to the present invention neutralize bone disease factor MCP-1, thereby reducing the collagen epitope (CTX-II) and collagen metabolism factors (MMP1 and MMP3) relating to collagen absorption in the body. In addition, it was confirmed that the expression of the SOX9 gene and anti-inflammatory cytokines (TGF-? and IL-10) related to cartilage differentiation was significantly increased. Thus, the present invention has excellent regenerative ability against osteoarthritis and excellent pain suppression and alleviation effects, and thus can be effectively used for preventing or treating bone diseases such as osteoarthritis.
