Animal models have enhanced our understanding of the pathogenesis of autoimmune diseases. For these models, genetically identical, inbred mice have commonly been used. Different inbred mouse strains, however, show a high variability in disease manifestation.

GM-CSF activates hematopoietic cells and recruits neutrophils and macrophages to sites of inflammation. Inhibition of GM-CSF attenuates disease activity in models of chronic inflammatory disease. Effects of GM-CSF blockade were linked to modulation of the effector phase, whereas effects on early pathogenic events, for example, Ab production, have not been identified.

Cytokines are key regulators of physiological inflammatory responses, while aberrant cytokine expression contributes to pathogenesis of autoimmune diseases. We noted increased IL-6 levels in human and murine epidermolysis bullosa acquisita (EBA), a prototypic organ-specific autoimmune bullous dermatoses (AIBD) induced by autoantibodies to type VII collagen (COL7). In contrast to rheumatoid arthritis, blockade of IL-6 led to strikingly enhanced experimental EBA, while treatment with recombinant IL-6 was protective.
