The Discovery: Hepatitis C Virus
The story of the Hepatitis C virus (HCV) began in the 1970s and 1980s when scientists were trying to identify the cause of post-transfusion hepatitis, a serious liver disease that was not attributable to hepatitis A or B.
Harvey J. Alter– Nobel Prize in Physiology or Medicine 2020
Harvey J. Alter’s research at the National Institutes of Health (NIH) focused on the identification of blood-borne viruses. He was instrumental in demonstrating that there was a virus responsible for transfusion-associated hepatitis that was distinct from known viruses. (Source)
Michael Houghton– Nobel Prize in Physiology or Medicine 2020
Michael Houghton, working at Chiron Corporation, collaborated with Alter to isolate the genetic material of the new virus. His team’s innovative use of molecular cloning techniques enabled them to identify the HCV genome, marking a crucial step in understanding the virus. (Source)
Charles M. Rice– Nobel Prize in Physiology or Medicine 2020
Charles M. Rice further advanced the discovery by demonstrating that the cloned RNA from HCV was infectious when introduced into chimpanzees. This work confirmed that the identified virus was indeed responsible for hepatitis C. (Source)
