1 RESULTS: Tofacitinib treatment of CD4+ T cells originating from synovium and peripheral blood inhibited the production of interleukin-17 (IL-17) and interferon-gamma (IFNgamma) in a dose-dependent manner, affecting both proliferation and transcription, but had no effect on IL-6 and IL-8 production. tofacitinib interleukin 6 Homo sapiens
2 However, conditioned medium from CD4+ T cells cultured with tofacitinib inhibited IL-6 production by RASFs and IL-8 production by CD14+ monocytes. tofacitinib interleukin 6 Homo sapiens
3 Treatment of SCID-HuRAg mice with tofacitinib decreased serum levels of human IL-6 and IL-8 and markedly suppressed invasion of synovial tissue into cartilage. tofacitinib interleukin 6 Homo sapiens
4 CONCLUSION: Tofacitinib directly suppressed the production of IL-17 and IFNgamma and the proliferation of CD4+ T cells, resulting in inhibition of IL-6 production by RASFs and IL-8 production by CD14+ cells and decreased cartilage destruction. tofacitinib interleukin 6 Homo sapiens
