These physiological processes are induced by the binding of TWEAK to fibroblast growth factor-inducible 14 （Fn14）, a highly inducible cell-surface receptor that is linked to several intracellular signaling pathways, including the nuclear factor-KB （NF-KB） pathway. This review discusses the role of the TWEAK-Fn14 axis in several rheumatic diseases and the potential therapeutic benefits of modulation of the TWEAK-Fn14 pathway.展开更多
