...The medicine fights the cytokine storm — a potentially lethal immune overreaction to the coronavirus infection that is believed to be responsible for much of the deaths associated with the disease.
It uses exosomes — tiny carrier sacs that shuttle materials between cells — to deliver a protein called CD24 to the lungs, which Arber has spent decades researching.
“This protein is located on the surface of cells and has a well known and important role in regulating the immune system,” said researcher Shiran Shapira of Arber’s lab.
The protein helps calm down the immune system and curb the storm.
