The circRERE/miR-144-3p/TLR2/MMP9 Signaling Axis in COPD Pulmonary Monocytes Promotes the EMT of Pulmonary Epithelial Cells

Using a co-culture system, scientists identified that the TLR2/MMP9 axis in pulmonary monocytes promoted the epithelial mesenchymal transition (EMT) of pulmonary epithelial cells.
