We next analyzed the levels of Fgr expression in the published human lung disease cell atlas database and observed that Fgr is also upregulated in interstitial lung disease (ILD) (Fig. S4A), and idiopathic pulmonary fibrosis (IPF) (Figs. S4B, 8), relative to control lungs. The gene discussed is FGR; the disease is interstitial lung disease.
