The scope of receptor editing and its association with autoimmunity.
Random assembly of antibody variable (V), diversity (D) and joining (J) gene segments creates a vast repertoire of antigen receptors, including autoreactive ones. Three ways that are known to reduce autoreactivity in the B-cell compartment include clonal deletion, functional inactivation and receptor editing, a mechanism involving a change in antigen receptor specificity through continued V(D)J recombination. New data suggest that editing can efficiently eliminate autoreactivity, yet, in an autoimmune context, secondary antibody gene rearrangements might also contribute to autoimmunity.
