UMAP visualization (Figure 1C) and cell ratio analysis (Figure 1D) illustrate the predominance of AMs in the sham condition (84.47% in WT sham group, 84.45% in Pad2−/− sham group), with myeloid cells emerging as the major population post‐PA infection (87.94% in WT PA group and 89.67% in Pad2−/− PA group). This evidence concerns the gene PADI2 and infection.
