Whole tissue cervical mapping of HPV infection: Molecular evidence for focal latent HPV infection in humans
In this study, we aimed to provide molecular evidence of HPV latency in humans and discuss potential challenges of conducting studies on latency. We analyzed the entire cervix of two women who underwent hysterectomy unrelated to cervical abnormality. The cervices were sectioned into 242 and 186 sets respectively, and each set was tested separately for HPV using the SPF10-PCR-DEIA-LiPA25 system. To identify whether there was any evidence of transforming or productive infection, we used the biomarkers E4 and P16INK4a to stain slides immediately adjacent to HPV-positive sections. HPV was detected in both cervices. In patient 1, 1/242 sets was positive for HPV31. In patient 2, 13/186 sets were positive for HPV18 and 1/186 was positive for HPV53. The infection was very focal in both patients, and there was no sign of a transforming or productive infection, as evaluated by the markers E4 and P16INK4a. Had we only analyzed one set from each block, the probability of detecting the infection would have been 32.3% and 2%, respectively.Our findings support the idea that HPV may be able to establish latency in the human cervix; however, the risk associated with a latent HPV infection remains unclear.
期刊介绍:
The official Journal of the International Papillomavirus Society Papillomavirus Research (PVR), the Journal of HPV and other Small DNA Tumor Viruses publishes innovative papers related to all aspects of papillomaviruses and other small DNA tumor viruses. The official journal of the International Papillomavirus Society, PVR is an open access publication that aims to bring together virologists, immunologists, epidemiologists and clinicians working in the booming field of HPV and animal papillomaviruses, polyomaviruses and other small DNA tumor viruses and their associated diseases, in order to foster and facilitate interdisciplinary communication. The journal welcomes original research articles, reviews, short communications, opinion articles and regional update reports on papillomaviruses and other tumor viruses in the following sections: a. Biology of papillomaviruses and related viruses from life cycle to cancer b. Epidemiology etiology and natural history studies c. Natural and induced immunity including vaccine research d. Intervention studies and strategies including i. Clinical studies and trials ii. HPV treatments iii. HPV vaccination programs iv. Diagnostics and screening e. Infection and disease prevention, modeling studies f. Guidelines and public health recommendations g. HPV Studies in special populations Regional and local studies on these viruses.
