Human papillomavirus (HPV) is the agent of the most common sexually transmitted diseases causing a variety of clinical manifestations ranging from warts to cancer. Oncogenic HPV infection is the major cause of cervical cancer and less frequently of penile cancers. Its presence in semen is widely known, but the effects on fertility are still controversial. We developed a new approach to evaluate virus localisation in the different semen components. We analysed also the specific genotype localisation and viral DNA quantity by qPCR. Results show that HPV DNA can be identified in every fraction of semen: spermatozoa, somatic cells and seminal plasma. Different samples can contain the HPV DNA in different fractions and several HPV genotypes can be found in the same fraction. Additionally, different fractions may contain multiple HPV genotypes in different relative quantity. We analysed the wholeness of HPV DNA in sperm cells by qPCR. In one sample more than half of viral genomes were defective, suggesting a possible recombination event. The new method allows to easily distinguish different sperm infections and to observe the possible effects on semen. The data support the proposed role of HPV in decreased fertility and prompt new possible consequences of the infection in semen.

Developing human papillomavirus (HPV) therapeutic DNA vaccines requires an effective delivery system, such as cell-penetrating peptides (CPPs). In the current study, the multiepitope DNA constructs harboring the immunogenic and conserved epitopes of the L1, L2, and E7 proteins of HPV16/18 (pcDNA-L1-L2-E7 and pEGFP-L1-L2-E7) were delivered using KALA and REV CPPs with different properties in vitro and in vivo. Herein, after confirmation of the REV/DNA and KALA/DNA complexes, their stability was investigated against DNase I and serum protease.

Human papillomavirus (HPV) is a major global health issue and is recognized as the leading cause of cervical cancer. While prophylactic vaccination programs have led to substantial reductions in both HPV infection rates and cervical cancer incidence, considerable burdens of HPV-related diseases persist, particularly in developing countries with inadequate vaccine coverage and uptake. The development of therapeutic vaccines for HPV represents an emerging strategy that has the potential to bolster the fight against cervical cancer.

Background: Human papillomavirus (HPV) is a prevalent infection affecting both men and women, leading to various cytological lesions. Therapeutic vaccines mount a HPV-specific CD8+ cytotoxic T lymphocyte response, thus clearing HPV-infected cells. However, no therapeutic vaccines targeting HPV are currently approved for clinical treatment due to limited efficacy.

Persistent infection with high-risk human papillomavirus (hrHPV) is a major cause of cervical cancer. The effectiveness of current HPV-DNA testing, which is crucial for early detection, is limited in several aspects, including low sensitivity, accuracy issues, and the inability to perform comprehensive hrHPV typing. To address these limitations, we introduce MTIOT (Multiple subTypes In One Time), a novel detection method that utilizes machine learning with a new multichannel integration scheme to enhance HPV-DNA analysis.

Background: The correlation between methylation of paired box gene 1 () and sex determining region Y-box 1 () with human papillomavirus (HPV) infection and the progression of cervical lesions is not well understood. This study aims to explore the potential value of and as diagnostic biomarkers for cervical diseases.
Methods: A total of 139 cervical biopsy tissue samples were obtained from the Department of Pathology, the Seventh Medical Center, Chinese PLA General Hospital from 2021 to 2023.
