In horses, immune-mediated muscle disorders can arise from an overzealous immune
response to concurrent infections or potentially from an inherent immune response to host …

Background The cause of immune-mediated myositis (IMM), characterized by recurrent,
rapid-onset muscle atrophy in Quarter Horses (QH), is unknown. The histopathologic …

Background An E321G mutation in MYH1 was recently identified in Quarter Horses (QH)

Background Immune‐mediated myositis (IMM) in American Quarter Horses (QHs) causes
acute muscle atrophy and lymphocytic infiltration of myofibers. Recently, an E321G mutation …

Horses affected by chronic piroplasmosis may develop poor performance and muscle
atrophy. Here we investigate the pathological and immunopathological aspects of myopathy …

Background Immune‐mediated myositis (IMM) is a cause of rhabdomyolysis, stiffness, and
muscle atrophy predominantly affecting Quarter horses. Limited information is available with …
