Research Abstract |
Previously, we demonstrated that the decoy for NFIL-6 inhibited COX2mRNA expression significantly (about 30%) in vitro on cultured synovial cells from the patients with RA. In the present study, to examine whether blockade of NFIL-6 signals could ameliorate arthritis, a histopathological comparative study was performed between OPN-/-mice and their wild type littermates induced with a murine arthritis model, AIA (antigen-induced arthritis). As a result, the severity of AIA on OPN-/-mice was significantly less compared with that of their wild type littermates (mean score of histopathological severity; OPN-/-versus wild type: 1.94±1.06 versus 2.78±0.73, p<0.05). These result suggest that NFIL-6 may be a possible therapeutic target for RA.
