To reveal the mechanism of inflammation-accompanied osteoporosis, mouse CD11b cells and CD4+CD25+ T cells were cocultured. Our results showed that CD11b+ monocytes cocultured with CD4+CD25+ T cells generated significantly less osteoclasts than those cocultured with CD4+CD25− T cells. The levels of MMP-7 and 9 in coculture supernatant were decreased significantly when CD11b+ monocytes and CD4+CD25+ T cells were cocultured comparing to the CD4+CD25− T cell group. These results highlight the role of CD4+CD25+ T cells on rheumatic osteoporosis.
