Research Abstract

Extracellular domain of CD81 was expressed in E.coli and immunized into mice. Monoclonal antibodies against CD81 were established from these mice, and antibody treatment of RA was performed by using CIA rat model. Furthermore, quantitative sandwich ELISA system was established by using recombinant CD81 and anti-CD81 antibodies. CD81siRNA introduced into SW982 cells reduced the expression of inflammatory cytikines and synoviolin.
