Immunopathological features of myopathy associated with small-to-medium-sized vessel vasculitis and differences from autoimmune myositis

CONCLUSIONS: Patients with vasculitis demonstrated mild myofiber damage based on the lower involvement of CD56/NCAM-expressing myofibers compared to those with AIM. Complement component deposits on the vessel walls and hypervascularity in the endomysium areas may be immunopathological features of vasculitic myopathy.PMID:37706291 | DOI:10.55563/clinexprheumatol/hpoapl
