Immunopathogenesis of Immune-Mediated Necrotizing Myopathy: Insights Drawn from Pathological Phenotypes and Mechanistic Elaboration
Immune-mediated necrotizing myopathy (IMNM) is a distinct subtype of idiopathic inflammatory myopathies (IIMs), classified by serum autoantibody status into anti-signal recognition particle (anti-SRP)-positive, anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR)-positive, and seronegative subgroups.
