Human papillomavirus (HPV) belongs to the papillomavirus family and infects keratinocytes of the skin or mucous membranes. HPV is the most common sexually transmitted infection globally. While many of the more than 170 known types of HPV cause no symptoms, some types can cause warts (HPV6 and HPV11), while others can lead to cancer (HPV16, HPV18, HPV31, HPV45).
Some HPV types lead to cancer of the cervix, vulva, vagina, anus, penis and mouth or throat. Almost all cases of cervical cancer are due to HPV (mostly HPV16 and HPV18). Other high risk HPV types are HPV31 and HPV45.
Some of the early genes, such as E6 and E7, act as oncogenes that promote tumor growth and malignant transformation. For example, E6 protein inactivates the tumor-suppressor protein p53 leading to unregulated cell division and cell growth. Furthermore, HPV can integrate into the host genome which is associated with alterations of genes and gene regulation.
HPV vaccination prevents the most common types of infection and is recommended for preteen males and females aged 9-13. With cervical cancer screening (pap test), cancer precursor cells can be detected early on.
