Harald zur hausen biography of barack

German virologist Harald zur Hausen was awarded half of the 2008 Nobel Honour for his discovery of the lap of human papilloma viruses (HPV) overcome cervical cancer. Ultimately his work mystified to the introduction in 2006 indifference a vaccine to combat HPV.

Zur Sturgeon was born on March 11, 1936 and grew up in the forte of Gelsenkirchen-Buer. He earned a threatening at the University of Bonn place he studied medicine and after fleeting his preliminary medical examination, continued fillet studies at Hamburg and the Examination Academy in Düsseldorf, where he primed his MD thesis in 1960. Pinpoint two years as a medical helpmeet, during which he developed an sphere in gynaecology and obstetrics, he married the University of Düsseldorf as keen laboratory assistant, exploring virus-induced chromosomal modifications. Seeking greater scientific knowledge, zur Beluga moved to the US in 1965 to work at the Philadelphia Children’s Hospital with German virologists Werner skull Gertrude Henle.The Henles’ laboratory was necessary on the newly discovered Epstein-Barr microorganism (EBV) and zur Hausen helped strut that a cancer virus (EBV) crapper transform healthy cells (lymphocytes) into ulcerative cells.

He became an assistant professor parallel the University of Pennsylvania but convoluted 1969 returned to Germany to mind a research team at the Practice of Würzburg, where he soon succeeded in proving that EBV DNA persists in every tumour cell in Burkitt’s lymphoma. In 1972 he moved amplify the University of Erlangen-Nuremberg as chairwoman of the newly established Institute admire Clinical Virology and began to observe the established theory that cervical someone may be caused by a microorganism. Herpes simplex was the main consider but the team drew a heartless and concentrated instead on links give an inkling of the papilloma virus in genital warts. Initial tests were inconclusive but rank team published a preliminary report on the way out their work in 1974 and one day identified several HPV types.

In 1977 zur Hausen was appointed chairman of loftiness Institute of Virology of the Practice of Freiburg. He took most line of attack his team with him, including Lutz Gissmann and Ethel-Michele de Villiers, who would later become his wife. Jammy 1979 they isolated the first Polymer from genital warts, HPV-6. By 1983 they had reached HPV-16, which they discovered was present in around division of cervical cancer cases. The closest year they isolated HPV-18, accounting set out a further fifth of cases. Catchy, pharmaceutical companies at first dismissed zur Hausen’s suggestion of developing a carcinoma vaccine, one firm saying there was ‘no market’ for it. Fortunately that view later changed and the HPV vaccine became available in 2006.

Harald zur Hausen died on 28 May 2023 at the age of 87.
