The elevated HER2 transcription in myofibroblasts from IPF lungs was further confirmed by analyses of published scRNA-seq datasets (Fig. S4 E; Adams et al., 2020; Habermann et al., 2020; Liu et al., 2021; Morse et al., 2019; Tsukui et al., 2020). The gene discussed is ERBB2; the disease is idiopathic interstitial pneumonia.
