An early event after lung injury is extracellular matrix remodelling. Here, the authors show that thrombospondin-1 (TSP1) from megakaryocytes/platelets protects the lung’s extracellular matrix, particularly basement protein COL6. Mice without TSP1 had greater lung damage and neutrophil activity, showing TSP1 reduces injury severity.
