Explained: How the immune system goes awry in severe Covid-19 cases

“These findings reveal how the immune system goes awry during coronavirus infections, leading to severe disease, and point to potential therapeutic targets,” senior author Bali Pulendran of Stanford Medicine said in a statement. The study is published in Science.

The researchers analysed the immune response in 76 people with Covid-19 and in 69 health people. They found enhanced levels of molecules that promote inflammation in the blood of severely ill patients. Three of these molecules are known to be associated with lung inflammation in other diseases, but had not been shown previously in Covid-19 infections.
