Novel mechanisms of CTLA-4 inhibition on bone remodeling / 中国免疫学杂志

ABSTRACT

In recent years,the CTLA-4 immunoglobulin biologics,a negative regulator in the immune system,have been obtained due attention in autoimmune diseases,transplantation rejection,and antineoplastic agents.CTLA-4 can inhibit T cell activation,reduce the expression of RANKL and other cytokines through regulating immune response,and effectively alleviate the process of bone resorption.According to previous study,CTLA-4 was involved in osteoclast-induced bone destruction and bone remodeling.In this review,the effect of CTLA-4 on the autoimmune diseases,on the osteoclast formation,and on the alveolar bone remodeling in the periodontal tissue was involved,and the related research were also evaluated to look forward to possible future basic research and clinical application direction.
