| Research Abstract |
We reported that decoy receptor 3(DcR3), a member of TNF receptor superfamily, inhibits Fas-induced apoptosis in THP-1 monocyte/macrophage cells and that DcR3 increases VLA4 adhesion molecule in THP-1 inhibiting cycloheximide-induced apoptosis. We also reported that serum DcR3 is elevated in patients with RA. Further, we reported that DcR3 inhibits the proliferation of RA synovial cells induced by inflammatory cytokines and the activation of MAPK by using TL1A expressing on the cell surface as a receptor. DcR3 is deeply involved in the pathogenesis of RA by not only as a decoy receptor against Fas ligand, but also as a ligand to inhibit apoptosis by increasing cell adhesion and to inhibit cytokine-induced cell proliferation. We revealed that DcR3 is a possible treatment target of RA.
