Abstract
In the present study, we characterized murine TWEAK and its receptor (Fn14) by generating cDNA transfectants and specific monoclonal antibodies (mAbs). Recombinant murine TWEAK bound to murine Fn14-transfected L5178Y (mFn14/L5178Y) cells and induced cell death. Some anti-human Fn14 mAbs we previously generated strongly cross-reacted with murine Fn14 and induced cell death in mFn14/L5178Y cells. Murine TWEAK-transfected L5178Y cells expressed murine TWEAK on cell surface and secreted functional TWEAK, which were detected by a newly generated anti-murine TWEAK mAb (MTW-1). Although thioglycolate-elicited murine peritoneal macrophages did not express a detectable level of TWEAK on their surface, they secreted functional TWEAK that was cytotoxic against mFn14/L5178Y cells and neutralized by MTW-1. The anti-murine TWEAK and Fn14 mAbs will be useful for further investigating the physiological and pathological functions of TWEAK and Fn14.Entities:
