背景介绍
  • Tumor necrosis factor alpha (TNFa) is a multifunctional proinflammatory cytokine synthesized mainly by nucleated blood 
    cells as a 233 aa type II transmembrane protein which is cleaved by ADAM17 between aa 76-77 to form a soluble 
    homotrimeric complex. TNFa plays a role in lipid metabolism, coagulation, and endothelial function and has been 
    associated with cancer, infection and inflammation (including inflammatory bowel disease), ischemia/reperfusion injury 
    and heart failure, and insulin resistance.
