    ABSTRACT: The goal of this study was to examine the role of CD8 T-cell responses to human papillomavirus type 16 (HPV-16) in a favorable clinical trend in women being studied for abnormal Pap smear results. Human papillomavirus-deoxyribonucleic acid testing and enzyme-linked immunospot assay using the HPV-16 E6 and E7 antigens were performed. The subjects with subsequent normal histologic diagnoses were considered to be "regressors" (n = 28), whereas those with histologic diagnoses of cervical intraepithelial neoplasia 1, 2, or 3 were considered to have short-term persistence of cervical abnormality and were designated to be "persistors" (n = 37). There was a higher percentage of CD8 T-cell responses to the E6 antigen in the regressors (15/28 or 53.6%) when compared with the persistors (10/37 or 27.0%; p = .04), but there was no recorded response difference for the E7 antigen. Results were the same when the analyses for E6 included only subjects who were high-risk HPV-positive (p = .01). The CD8 T-cell immune responses to the HPV-16 E6 antigens but not to E7 antigens are associated with a favorable clinical trend regardless of HPV types currently detected.
