Lack of chromatin and nuclear fragmentation in vivo impairs the production of lupus anti-nuclear antibodies.

Abstract

Nuclear autoantigens in systemic lupus erythematosus are thought to derive primarily from apoptotic cells, yet there is no direct evidence that interfering with apoptosis impairs the generation of lupus autoantibodies. Here we use a mouse model that lacks the endonuclease caspase-activated DNase (CAD), resulting in an absence of chromatin and nuclear… (More)
