The transcription factor NF-kappaB has been shown to play a role in protecting cells against death mediated by TNF We show here that NF-kappaB also has a role in regulating Fas / APO-1 / CD95 -mediated death , a major pathway of peripheral T cell death .
 ( protein: NF-kappaB, None) , ( protein: transcription factor, None) , ( protein: Fas, None) , ( protein: APO-1, None) , ( protein: NF-kappaB, None) , ( protein: CD95, None) , ( cell type: peripheral T cell, None) , ( protein: TNF, None)
