Abstract
Inclusion body myositis (IBM) is a progressive inflammatory skeletal muscle disease of unknown cause and without effective treatment. This article discusses existing literature, emphasizing disease mechanisms and models. In particular, it addresses limitations in the beta-amyloid-mediated theory of IBM myofiber injury, flawed rationales of animal models of this disease, and recent reports regarding treatment.
