Genetic determinants of autoimmunity are largely found within the major histocompatibility complex MHC and the genotype to serotype to phenotype concept is supported in a number of autoimmune diseases where both genotype and serotype are well established. The serotype is autoantigen-driven with evidence of epitope spreading as the disease evolves from asymptomatic to pathogenic autoimmunity. In rheumatoid arthritis and multiple sclerosis where the autoantigens are poorly characterised the use of an array in animal models may produce a hint of what happens in human disease. A more complete picture will be obtained from animals transgenic for human MHC immunised with known human autoantigens. Epitope spreading in animal models of rheumatoid arthritis and multiple sclerosis In a recent issue Kidd and colleagues 1 have attempted an analysis of epitope spreading in murine collagen-induced arthritis and experimental autoimmune encephalomyelitis as models of rheumatoid arthritis RA and multiple sclerosis MS . This is a courageous undertaking because the major histocompatibility complex MHC differs between mouse and man and therefore any MHC-dependent autoimmune .
