Analysis of the Mouse PEC Landscape database containing scRNA-seq gene expression data for PECs from healthy mice and mouse models of kidney disease [9] (Table 1) revealed that Aldh1a2 expression in PECs increased substantially in murine anti-GBM glomerulonephritis, on day 5 after intravenous injection of sheep anti-rat glomeruli serum (Figure 2C). This evidence concerns the gene ALDH1A2 and glomerulonephritis.
