摘要: Twenty patients with clinically and microscopically confirmed lichen planus were studied immunohistochemically. Monoclonal antibody to HLA-DR antigens polyclonal antisera S-100 protein muramidase applied paraffin-embedded sections for the purpose of elaborating on pathogenesis this disease. Trypsin incubation was also done in order determine its effect immunostaining. Langerhans cells identified anti-S-100 anti-HLA-DR, macrophages antimuramidase anti-HLA-DR. Keratinocytes expressed membrane activity tissue. Trypsinization significantly improved expression antigens. It concluded that cells, macrophages, keratinocytes play important roles antigen processing and/or phagocytosis during natural history
