Canadian research team makes breakthrough in understanding immune response to COVID-19
LONDON, ONT. -- A research team out of London, Ont. says it is the first in the world to profile the bodys immune response to COVID-19, which could have big implications for treatment.

The team from the Lawson Health Research Institute and Western University say they have found six molecules that could be used as targets for treating the virus.

Since the beginning of the pandemic several studies around the world have reported that the immune system can overreact to the virus, causing a cytokine storm.

A cytokine storm can cause hyperinflammation in patients, which can have deadly results.

Until now clinicians did not know which molecules in the body to target in order to combat the inflammation.

Our study takes away the guessing by identifying potential therapeutic targets for the first time, said lead researcher Dr. Douglas Fraser with Lawson and Western.

Of 57 molecules studied a total of six were found to be elevated in critically ill COVID-19 patients.

The research team also enlisted artificial intelligence to confirm their findings.

They even were able to identify one molecule, called heat shock protein 70, as being strongly associated with an increased risk of death when found in the blood during the early stages of infection.
