## Abstract Programmed cell deathβ1 (PDβ1, CD279) and its widely expressed, inducible ligand, PDβL1 (CD274), together dampen T cell activation, but whether they are essential for allograft tolerance is unknown. We show, using geneβdeficient mice and blocking mAbs in wildβtype mice, that costimulati
## Abstract Disruption of the programmed deathβ1 (PDβ1) pathway leads to breakdown of peripheral tolerance and initiation of autoimmunity. The molecular pathways that mediate this effect remain largely unknown. We report here that PDβ1 knockout (PDβ1^β/β^) mice develop more severe and sustained Agβ
