The incidence of human papillomavirus (HPV)-related cervical
intraepithelial neoplasia (CIN) and cervical cancer is increased with
immunodeficiency, but the role of immune response, including cell- mediated
immunity, in disease prevention is not well understood. In this study,
T-cell proliferative responses to six synthetic peptides with predicted
immunogenic determinants from the HPV-16 E4, E6, E7, and L1 open reading
frames were analyzed in 22 sexually active women with new-onset CIN and 65
sexually active women without cervical disease, characterized by cytology,
colposcopy, and HPV testing. T-cell proliferative responses were
demonstrated to all six HPV-16 peptides. Although not statistically
significant, rates of reactivity to E6 (24- 45) were higher among sexually
active women without disease (26%) than among women with current CIN (7%),
as was the overall number of peptides stimulating a response. Women with
CIN may not respond to selected HPV antigens as well as women without
disease do.
