Emerging therapies for human papillomavirus infection

Abstract

Human papillomavirus (HPV) is the most common sexually transmitted infection, with > 50% of sexually active women being affected. The virus causes a wide variety of benign and pre-malignant epithelial tumours and although most infections are transient, it is estimated that 1% of the sexually active population in the US have clinically apparent genital warts. A subset of genital HPVs, termed high-risk HPVs, is highly associated with the development of genital cancers including cervical carcinoma. Therapies for these HPV related cancers are however outside of the scope of this review. The absence of a simple monolayer cell culture system for analysis and propagation of the virus has substantially retarded progress in the development of diagnostic and therapeutic strategies for HPV infection. In spite of these difficulties, great progress has been made in the elucidation of the molecular controls of virus gene expression, replication and pathogenesis, and there has been some progress in the development of prophylactic and therapeutic vaccines and of other therapies.
