Harald zur Hausen

Harald zur Hausen was a German virologist whose research established that human papillomaviruses cause cervical cancer. He received the 2008 Nobel Prize in Physiology or Medicine.

Lutz Gissmann: A German virologist who helped identify and characterize human papillomavirus types associated with genital warts and cervical cancer. He collaborated with zur Hausen on identifying HPV types in genital lesions and cervical tumors.
Human papillomavirus: A large family of viruses that infect skin and mucosal surfaces in humans. Zur Hausen identified particular HPV types in cervical cancers, establishing the causal connection.
Papillomavirus: A family of non-enveloped DNA viruses that infect vertebrates and can cause warts or tumors. Zur Hausen’s work focused on human members of this broader virus family.
HPV vaccine: A vaccine that protects against selected human papillomavirus types associated with cancer and genital warts. Zur Hausen’s causal finding provided the scientific basis for preventing HPV-linked cancers through vaccination.
Ethel-Michele de Villiers: A virologist known for research identifying and classifying human papillomaviruses. Her HPV research formed part of the scientific work associated with zur Hausen’s group.
HPV E6: A viral oncoprotein produced by high-risk human papillomaviruses that promotes degradation of the p53 tumor-suppressor protein. E6 helps explain how the high-risk HPV types linked to cervical cancer undermine cell-cycle safeguards.
Cervical cancer epidemiology: The study of patterns, causes, and risk factors of cervical cancer in populations. Epidemiological clues linking sexual transmission to cervical cancer helped motivate the search for an infectious cause.
Cervical screening: Testing asymptomatic people for cervical precancers or cancer, using cytology, HPV testing, or both. Recognition of HPV as the cause made testing for high-risk viral infection central to prevention.
Nobel Prize in Physiology or Medicine: An annual international award recognizing discoveries in physiology or medicine. Zur Hausen received the 2008 prize for discovering that human papillomaviruses cause cervical cancer.
HPV E7: A viral oncoprotein produced by high-risk human papillomaviruses that disrupts the retinoblastoma protein’s control of cell division. E7 is another mechanism by which cancer-associated HPV types drive infected cells toward uncontrolled growth.
