Single-cell RNA sequencing (scRNAseq) analysis and transcriptional profiling indicated similarities in expression profiles between idiopathic pulmonary fibrosis (IPF) and COVID-19 [13,14], while CoV-2 infection has been suggested to stimulate the expression of major pro-fibrotic factors including TGFβ [15]. This evidence concerns the gene TGFB1 and idiopathic pulmonary fibrosis.
