Chasing the cells that predict death from severe COVID-19

(Gladstone Institutes) By studying T cells, a team of scientists at Gladstone Institutes has uncovered fundamental differences between patients who overcome severe COVID-19 and those who succumb to it. The team also found that dying patients harbor relatively large numbers of T cells able to infiltrate the lung, which may contribute to the extensive lung deterioration that is a hallmark of fatal COVID-19.
