Autoaggressive myocytotoxic T lymphocytes expressing an unusual gamma/delta T cell receptor.

Abstract excerpt

Polymyositis mediated by gamma/delta T cells is a unique disease in which autoaggressive T lymphocytes surround, invade, and destroy muscle fibers. Histochemically, the vast majority of muscle-infiltrating T cells in a patient with polymyositis were reactive with a pan-gamma/delta T cell receptor (TCR)-specific monoclonal antibody (TCR-delta 1+), but unlike > 90% of peripheral blood gamma/delta T cells, these...
