Human Papillomavirus-Associated Tumor Extracellular Vesicles in HPV Tumor Microenvironments.

Most infections with human papillomaviruses (HPVs) are self-resolving and asymptomatic. However, some infections can lead to the development of cancer at different mucosal sites, such as the cervix and the head and neck. Head and neck cancers (HNCs) are dichotomized into HPV-positive (HPV) or HPV-negative (HPV) based on their respective etiologies.
