However, present results and previous evidence suggest a role of PTX3 in lung repair in experimental models of lung injury (16), an association of PTX3 and Primary Graft Dysfunction (PGD) in IPF recipients after lung transplant (57), or a potential role of PTX3 produced by fibroblasts and bronchial epithelial cells in fibrocyte differentiation in vitro (28). The gene discussed is PTX3; the disease is idiopathic pulmonary fibrosis.
