SARS antibodies can block coronavirus infection, claim researchers
An antibody from a patient who recovered from SARS has been shown
to block COVID-19 infection in a laboratory setting, researchers said Monday in
another potential breakthrough in the search for coronavirus treatment.
Scientists
based in Switzerland and the United States previously isolated the antibodies
from the patient in 2003, following the SARS outbreak that killed 774 people.
They
experimented with 25 different types of antibodies -- which target specific
protein spikes on viruses -- to see if they could prevent cells becoming
infected with COVID-19.
Both SARS and the pathogen which causes COVID-19 are coronaviruses, thought to have come from animals, and so their structures are similar.
