NCR3LG1 and squamous cell intraepithelial neoplasia: The findings of our present study demonstrate for the first time that B7-H6 is not expressed in the abnormal epithelial cells of low-grade squamous intraepithelial lesions (LSIL); while, in contrast, when the stage of the lesion is more advanced, such as high-grade squamous intraepithelial lesion (HSIL) or both cancer types, squamous cervical carcinoma (SCC) or uterine cervical adenocarcinoma (UCAC), there is a positive correlation with the immunoreactive score (IRS) for immunohistochemical B7-H6 detection.
