Abstract
Epitope (determinant) spreading is the development of immune responses to endogenous epitopes secondary to the release of self antigens during a chronic autoimmune or inflammatory response. The past year has seen considerable advances in our understanding of the contribution of epitope spreading to the chronic pathogenesis of experimental T-cell-mediated and antibody-mediated autoimmune diseases. Most significantly, conclusive functional evidence for a major role for epitope spreading in the chronic pathogenesis of murine relapsing-remitting experimental autoimmune encephalomyelitis, a CD4+ T-cell-mediated model of multiple sclerosis, was forthcoming.

The extent of activation of relapse-associated epitopes was shown to correlate with the degree of tissue damage during acute disease. Splenic T cells specific for the relapse-associated epitopes could transfer disease to naive mice and tolerance to the intact PLP protein during disease remission (which inhibited responses to both the initiating and relapse-associated epitope) prevented disease relapses.
