HLA-E expression in cervical epithelium and cervical carcinoma. Human leukocyte antigen E (HLA-E) immunohistochemistry was performed with the MEM-E/02 antibody against HLA-E. A) Weak HLA-E expression in normal cervical squamous epithelium. B) Weak HLA-E expression in normal cervical cylindrical epithelium. C) Strong HLA-E expression in endocervical-type cervical adenocarcinoma (AC) D) Strong HLA-E expression in endometrioid-type AC. E) Moderate HLA-E expression in endocervical-type AC with normal stromal expression. F) Moderate HLA-E expression in endocervical-type AC with strong stromal expression. G) Weak to negative HLA-E expression in endocervical-type AC. H) Strong HLA-E expression in cervical squamous cell carcinoma. I) Weak to negative HLA-E expression in cervical squamous cell carcinoma. Bar (blue, left bottom) represents 100 μm.
