T-cell abnormalities in severe COVID-19 cases

There is an idea within the coronavirus research field that there is some kind of T-cell abnormality in critically ill COVID-19 patients, but specific details have not yet been clarified. To shed light on the problem, a research collaboration based in Kumamoto University (Japan) has performed a genetic analysis of T-cells from lung tissue of COVID-19 patients. Their work revealed abnormalities in T-cells that resulted in overactivation that may cause severe pneumonia. The researchers believe that their findings will lead to new ways of avoiding severe pneumonia caused by coronavirus infections.
