Nobel
Prize 2020 in Physiology or Medicine
Was jointly
awarded to Harvey J. Alter, Michael
Houghton and Charles M. Rice for the discovery
of Hepatitis C virus
The virus is a commonly cause of live cancer and major reason people need a liver transplant.
The
Nobel Prize committee said their discoveries ultimately “saved millions of
lives”.
Hepatitis
C virus?
Hepatitis
C is a blood-borne virus and causes Hepatitis C disease which affect the liver.
Globally,
an estimated 71 million people have chronic hepatitis C virus infection and a
significant number develop cirrhosis or liver cancer.
In
1960s, was huge concern that people receiving donated blood were getting
chronic hepatitis from an unknown, mysterious disease.
How
to discover a new virus?
Harvey
J. Was studying hepatitis in patients who had received blood transfusions,
found many unexplained infections. Hepatitis A and Hepatitis B virus infection
test showed that they were not the cause. His team demonstrated that blood from
these patients could transmit the disease to chimpanzees. New mysterious
illness was termed “non-A, non-B” hepatitis.
New
virus could not be isolated for several years. The traditional techniques used for
virus isolation. The collection of DNA fragments from the blood of an infected
chimpanzee thoroughly collect the Michael Houghton and his team. Novel RNA virus
found belonging to the Flavivirus family and named it the Hepatitis C virus.
This
new virus alone could cause hepatitis, Charles M. Rice used genetic
engineering, generated an RNA variant of the virus and injected it into the
liver of chimpanzees.
This
discovery is matter?
The
three Nobel laureates have design sensitive blood tests that have eliminated
the risk of transfusion-transmitted hepatitis. This discovery helped to develop
antiviral drugs directed at hepatitis C. Now raised hopes of eradicating the
virus from the world population.
“We try a lot of
methods, probably 30 or 40 different methodological approaches or seven years.
Finally, the development
of effective treatment and screening of blood transfusions, and protecting
population.
