Severe T cell hyporeactivity in ventilated COVID-19 patients correlates with prolonged virus persistence and poor outcomes

Abstract: Coronavirus disease 2019 (COVID-19) can lead to pneumonia and hyperinflammation. Here we show a sensitive method to measure polyclonal T cell activation by downstream effects on responder cells like basophils, plasmacytoid dendritic cells, monocytes and neutrophils in whole blood. We report a clear T cell hyporeactivity in hospitalized COVID-19 patients that is pronounced in ventilated patients, associated with prolonged virus persistence and reversible with clinical recovery. COVID-19-induced T cell hyporeact… Show more

“…Our data corroborated a role for altered erythropoiesis in COVID-19 with elevated circulating cfDNA originating from erythroid progenitors, especially in severe disease. Another feature of COVID-19 is lymphopenia in the peripheral blood (T, B, and NK cells), indicating impairment of adaptive immunity 67 . Absolute lymphocyte count was also low in SOT COVID-19 patients and our methylome analysis corroborated these findings with low/undetectable cfDNA levels from CD4 + T cells and CD8 + T cells.…”

“…The impact of viruses on the activation mechanisms of cellular stress in immunocompetent cells is also significant, as it causes polyclonal activation and apoptosis of lymphocytes (primarily T cells), pathological activation of macrophages, and immunosuppression [41].…”
