Abstract
Antibody responses against nucleosome core histones in systemic lupus erythematosus have been shown, by immunoblotting, to be directed largely against the trypsin-sensitive regions of the histones. These occur at the N-terminal regions of all 4 core histones and at the C-terminal ends of H2A and H3. Since these regions are often not the most antigenic when individual histones are used as immunogens, and appear to be exposed in the nucleosome, the active immunogens in systemic lupus erythematosus seem likely to be chromatin-bound, rather than free, histones
