Abstract:
Objective To study the regulatory effect of interleukin-17 on the production of inflammation and bone erosion related factors of fibroblast-like synoviocytes (FLSs) from rheumatoid arthritis (RA) patients and to investigate whether signal transducer and activator of transcription 3 (STAT3) is implicated in this regulatory effect.Methods FLSs were acquired through primary culture from RA patients.Receptor activator for nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) expression in FLSs were determined using western blot analysis.The level of IL-6,granulocyte-mac rop hage colony stimulating fac tor (GM-CSF)and IL-8 were determined by enzyme linked immunosorbent assay (ELISA) assay.Statistical product and service solutions (SPSS) 17.0 statistical software was used for single factor analysis of variance and LSD-t comparison between each two groups.Results IL-17 stimulated FLSs and promoted the release of IL-6,GM-CSF and IL-8 (t=2.135,P＜0.01) and increased the production of RANKL (t=2.105,P＜0.01) and reduced the production of OPG (t=2.502,P＜0.01).However,targeted silencing of STAT3 could inhibit the effect of IL-17 on FLSs [control group:IL-6 (512±18) pg/ml;GM-CSF (591±25) pg/ml;IL-8 (473±10) pg/ml;RANKL (2.310±0.096);OPG (0.614±0.311);IL-17 group:IL-6 (1 630±39) pg/ml;GM-CSF (1 825±18) pg/ml;IL-8 (2 804±41) pg/ml;RANKL (4.010±0.256);OPG (0.131±0.101);STAT3 silent group:IL-6 (405±21) pg/ml;GM-CSF (451±12) pg/ml;IL-8 (370±9) pg/ml;RANKL (0.850±0.298);OPG (1.120±0.342)].Conclusion STAT3 pathway is critical to IL-17-induced regulatory effect on the release of inflammation and bone erosion related factors of FLSs.IL-17 can induce the inflammation and bone erosion of RA via STAT3.
