N2 - Human papillomavirus type 16 (HPV-16) L1 - and E7-specific T cell responses were measured in 58 women with abnormal cervical cytology in a prospective study. On recruitment, patients responded most frequently and with the highest numbers of responding cells to the L1 region aa 311-345 and this response was significantly associated with the presence of cervical disease (P = 0-041). Responses to the L1 peptide aa 281-295 were significantly higher in patients with CIN III than in those with HPV/CIN I or CIN II lesions (P= 0.027). The E7 region aa 70-98 was the most immunogenic in patients with squamous intraepithelial lesions of the cervix (SIL) but the responses detected were not significantly higher than in patients without SIL. Following treatment, the T cell response profiles of patient groups did not change significantly. However, on analysis of the responses of individual patients with and without recurrent disease on follow-up, significant differences were found. Recurrence of disease was associated with T cell responses to the E7 region aa 70-98 at the patient's first clinic visit (P = 0.017). Recurrence of disease was also accompanied by an increase in the total number of L1-specific short-term T cell lines (STLs) at follow-up, whereas absence of disease was accompanied by a decrease in L1-specific STLs. The data also suggested a possible link between E7 70-98-specific responses and acquisition of disease by patients who were previously disease-free. Further studies are warranted to determine whether this response could be useful as a marker of recurrent disease in some patients.
