      Tumor necrosis factor (TNF) and the endothelial cells TNF receptors are shown with the other lipid membrane structures removed. The linear construct of etanercept is replaced by a model with a more three dimensional design. The interaction of TNF with etanercept is shown. etanercept, infliximab, and adalimumab all work by sopping up TNF in the body fluids.
      The significant response of RA to various treatments tells us a lot about its pathophysiology. Clearly, excess proinflammatory mediators, such as tumor necrosis factor (TNF), are playing a profound role, as shown by effectiveness of the BRMs.
