Viral Etiology of Polymyositis/Dermatomyositis 2013-11-17 .txt text/plain 10782 523 43 Thus, theories based on a viral etiology must invoke a highly un usual host response to ubiquitous agents, the existence of uncommon viruses with the abil ity to provoke the disorder, or the possibility that virus infections operate synergistically with other factors. Attempted isolation Electron-microscopic studies Viral probes Antiviral antibody titers Establishing clones from infiltrating T lymphocytes and screening their antigen specificities Exploring the antigen specificities of associated autoantibodies In vitro models of virus-infected muscle cells In vivo models of experimental polymyositis ceptually. In clinical studies, EBV transformed blood lymphocytes from both normal individuals and patients with autoimmune diseases pro duced monoclonal autoantibodies reactive with antigens in multiple organs [93] . Myocarditis and PM induced by coxsackievirus infection is mediated by immunopathologic mechanisms that may continue to dam age muscle fibers long after infectious virus and even viral antigens have been eliminated. ./cache/cord-022439-8wy7rpqv.txt ./txt/cord-022439-8wy7rpqv.txt
