项目摘要

Receptor activator of NF-kB ligand (RANKL) is a membrane-bound cytokine, which plays an important role in osteoclast differentiation and activation. We established a novel therapeutic approach against pathological bone resorption using RANKL vaccine. Administration of RANKL vaccine induced a rapid anti-RANKL antibody induction in mice, and efficiently suppressed bone destruction in arthritis model mice, SKG mice established by Dr Shimon Sakaguchi (Kyoto Univ.), and bone loss in ovariectomized mice.The results of the studies reported here demonstrate that a therapeutic vaccine approach, targeting RANKL, is useful to inhibit bone destruction in pathological bone-loss conditions such as rheumatoid arthritis (RA) and osteoporosis. We could not show the effects of the vaccine on periodontal disease-model since we failed to establish the model. Although we could not make it this time, the effects of the vaccine on mice RA-model, a kind of the inflammatory bone destruction model, suggest the possibility for the inhibitory effects on bone destruction in periodontal disease.Compared with the use of other therapeutic recombinant proteins against pathological antigens such as monoclonal antibodies, soluble receptor or other antagonists, a vaccine needs smaller doses of protein to induce its affect. Once the immune response is established by vaccination, it is easily maintained by boosting with the vaccine. The underlying pathology of bone destruction is similar in bone-related diseases such as RA, periodontitis and bone metastasis. This RANKL vaccination would be a novel approach to any kind of pathological bone destruction.
核因子-kB受体激活剂配体(RANKL)是一种膜结合型细胞因子,在破骨细胞分化和激活过程中发挥重要作用。我们建立了一种利用RANKL疫苗治疗病理性骨吸收的新方法。接种RANKL疫苗能迅速诱导小鼠产生抗RANKL抗体,并能有效抑制关节炎模型小鼠、东京大学Shimon Sakaguchi博士建立的SKG小鼠的骨破坏和去卵巢小鼠的骨丢失。研究结果表明,针对RANKL的治疗性疫苗方法在类风湿关节炎(RA)和骨质疏松症等病理性骨丢失情况下有助于抑制骨破坏。由于未能建立牙周病模型,我们无法显示疫苗对牙周病模型的影响。虽然这次我们没能来,但疫苗在小鼠RA模型上的作用表明,它对牙周病的骨破坏有抑制作用的可能性。与使用其他针对病理抗原的治疗性重组蛋白如单抗、可溶性受体或其他拮抗剂相比,疫苗需要较小剂量的蛋白质来诱导其作用。一旦通过接种疫苗建立了免疫反应,就很容易通过疫苗增强来维持这种免疫反应。骨破坏的基本病理在骨相关疾病中类似,如类风湿关节炎、牙周炎和骨转移。这种RANKL疫苗将是治疗任何类型的病理性骨破坏的一种新方法。
