It is suggested that the actin microfilament system plays a decisive role in the structural and functional integrity of the endothelial but not the epithelial barrier.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/9/1/93}, eprint = {//www.qdcxjkg.com/content/9/1/93.full.pdf}, journal = {European Respiratory Journal} }
