They are stored together in cytoplasmic granules and secreted into the extracellular compartment upon stimulation [6].COVID-19 ARDS is associated with release of biologically active neutrophil elastase-related proteinases to the airways and blood at a comparable level to non-COVID ARDS https://bit.ly/3nihvehThe authors thank Celia Moss (Birmingham Children's Hospital and University of Birmingham) for English editing.
