Cytokines and direct cell contact in synovitis: relevance to therapeutic intervention
HealthData.Gov
There is mounting evidence indicating that the synovial fibroblast is a direct effector of tissue injury and matrix remodeling in inflammatory synovitis. Through the elaboration of effector signals including cytokines…
