Viral type and CD1+ cells in HPV-induced lesions.
In vivo, HPV infection can display varying symptom complexes. At present 60 types of HPV are known, and some seem to be more efficient oncogenic agents than others. In particular, HPV 16 and 18 appear the types with the greatest oncogenic potential, being frequently found in cases of intraepithelial cervical neoplasia (CIN) and/or invasive carcinoma of the cervix. Many authors suggest that they might induce cell-mediated immunodeficiency into the lesions. This investigation was conducted on 15 women aged 17 to 40 (mean, 27.8). On the basis of cytological examination, colposcopy and biopsy, HPV-induced lesions were diagnosed. Biopsies were performed periodically for six months for HPV detection and typing. In addition, the cells of Langerhans were imaged by the indirect immunoperoxidase method. Variations in their number according to the HPV type involved were observed.
