The authors show that plasminogen activator inhibitor-1 (PAI-1) derived from cancer-associated fibroblasts promotes the invasion of esophageal squamous cell carcinoma (ESCC) cells and the migration of macrophages via lipoprotein receptor-related protein 1 (LRP1). High expression of PAI-1 and/or LRP1 is associated with poor prognosis in patients with ESCC, and the PAI-1/LRP1 axis could be a target of anticancer therapy.
