Abstract

Human papillomavirus (HPV) infection is associated with transformation and clonal expansion of infected epithelial cells, resulting in the production of a benign growth, i.e. a wart. Recently, however, HPV has emerged as the primary causative agent of cervical carcinoma, malignancy being associated with the presence of the viral genome (predominantly genotypes 16 and 18) in cancerous cells. The only HPV proteins reliably expressed in neoplastic lesions are the 'oncogenic' E6 and E7 proteins, that serve both as tumour-specific markers and potential targets for immunotherapeutic intervention. As intracellular (nuclear) proteins, the E6 and E7 gene products may be hidden from the humoral immune response. Attention has thus focused on the generation of a vaccine capable of inducing or stimulating a cellular immune response to HPV 16 and HPV 18 E6 and E7. Vaccine development has been constrained by the absence of an appropriate animal model, the oncogenic nature of E6 and E7 and technical difficulties associated with detection of cytotoxic T cell responses to these antigens. Despite these difficulties, vaccine strategies have now been devised based on immunisation with synthetic peptide, whole protein and a vaccinia virus recombinant. Phase I/II human clinical trials have been initiated, and preliminary results have demonstrated the induction of specific cellular immune responses after immunisation. The HPV-associated neoplasia in cervical cancer represents an excellent target for therapeutic intervention because the tumour-associated antigens are so clearly defined. As such, it provides an appropriate model for establishing the general principles of cancer immunotherapy in humans.
