The combinations of rhIL-6 and soluble IL-6 receptor- (sIL-6R) or rhIL-6 and tocilizumab (TCZ), a fully-humanized recombinant monoclonal antibody that neutralizes the interaction between IL-6 and IL-6R significantly reduced MMP-9 production by C28/I2 chondrocytes
The combinations of rhIL-6 and soluble IL-6 receptor- (sIL-6R) or rhIL-6 and tocilizumab (TCZ), a fully-humanized recombinant monoclonal antibody that neutralizes the interaction between IL-6 and IL-6R significantly reduced MMP-9 production by C28/I2 chondrocytes. chondrocytes although the number of NGAL-positive cells was significantly reduced by sIL-6R compared to its control group, but not from the combination of rhIL-6 plus TCZ compared to rhIL-6. In summary, these results showed that rhIL-6 stimulated the production of MMP-9, but not NGAL, in the C28/I2 chondrocyte collection. TCZ or sIL-6R suppressed rhIL-6-induced MMP-9 production. gene expression is definitely significantly up-regulated in response to the elevated levels of pro-inflammatory cytokines in the synovial fluid milieu, exemplified by intereukin-6 (IL-6), IL-1, IL-17, and tumor necrosis element- (TNF-) [1-3].
