Regulation of synovial cell apoptosis by proteasome inhibitor

Abstract

Apoptosis of synovial cells was induced by inhibition of proteasome function through the activation of caspase cascade, and this process was clearly modulated by cytokines. These data provide new insight into the regulatory mechanisms controlling synovial cells in rheumatoid synovitis by proteasome inhibitors, and might be useful for the design of new therapeutic strategies in rheumatoid arthritis.
