To understand how Car4-high ECs and other EC populations behave following influenza injury in the context of the entire lung and whether they undergo gene expression changes that may contribute to regeneration, we performed scRNA-seq on non-immune cells (CD45-) isolated from whole adult mouse lungs, both uninjured and at 14 days following H1N1 influenza infection. The gene discussed is PTPRC; the disease is influenza.
