Periodontitis, a chronic inflammation of the tooth gums, leads to unwanted bone loss as a response to inflammatory compounds such as interleukin\u20101\u03b2 (IL\u20101\u03b2). This excessive bone loss reflects an increased osteoclast formation and activity. Osteoclast formation is a multistep process driven by osteoclastogenesis supporting cells such as periodontal ligament fibroblasts. The inflammatory factors can induce osteoclastogenesis, probably also by affecting the periodontal ligament fibroblast. In this study we investigated how pre\u2010culture of periodontal ligament fibroblasts with IL\u20101\u03b2 affected osteoclastogenesis. Fibroblasts were pre\u2010cultured with IL\u20101\u03b2 and\/or dexamethasone, a commonly used anti\u2010inflammatory compound, before being co\u2010cultured with peripheral blood mononuclear cells (PBMCs). Pre\u2010culture with IL\u20101\u03b2 (1\u2013100\u2009ng\/ml) resulted in an increased number of adhered PBMCs as well as an increased mRNA expression of intercellular adhesion molecule\u20101 (ICAM\u20101), macrophage colony stimulating factor (M\u2010CSF) and IL\u20101\u03b2. Pre\u2010culture with IL\u20101\u03b2 also caused retraction of fibroblasts and an augmented formation of TRACP<jats:sup>+<\/jats:sup> multinucleated cells. Our data suggest that stimulation of fibroblasts with IL\u20101\u03b2 has a long\u2010lasting effect, leading to a significantly increased osteoclastogenesis. These results provide new insights for understanding excessive bone loss in periodontitis. J. Cell.
