Distinct muscle expression of type 1 interferon-inducible genes in inflammatory myopathies. Distinct muscle expression of type 1 interferon-inducible genes in dermatomyositis (DM) compared with polymyositis (PM) and inclusion body myositis (IBM). Muscle microarray data shown for 20 patients (five each with active dermatomyositis (DMA), active polymyositis (PMA), untreated IBM, and normal) with plotted mean values and error bars for mean ± standard error for each group. Highly expressed genes in DM muscle are orders of magnitude greater than in PM and IBM. Adapted from [19] with permission.
