The role of somatic hypermutation in the generation of pathogenic antibodies in SLE

Abstract excerpt

The formation of antibodies against double-stranded (ds)DNA is considered to be the serologic hallmark of systemic lupus erythematosus (SLE) and anti-dsDNA antibodies play an important role in the pathogenesis of the disease. Anti-dsDNA antibodies from lupus mice and SLE patients arise by somatic mutation. Importantly, autoantibodies in which somatic mutations have been reverted to germ-line V regions did not...
