Major cell types were annotated based on expression of canonical marker genes (AMp: CD68, CD163, FABP4, MARCO; monocytes: VCAN, FCN1; mDC: CD1C, CD1E, FLT3, LGALS2; cDC1: FLT3, LGALS2, CLEC9A, XCR1; neutrophils: FCGR3B, CXCL8, CSF3R; G0S2; Mast cells: TPSAB1, TPSB2, MS4A2, GATA2; T-cells: CD3D, CD3E, IL32; CD4 T-cells: CD4; CD8 T-cells: CD8A, CD8B; Tregs: FOXP3, IL2RA; NK-cells: TRDC, NKG7, KLRC1, XCL1, XCL2, KLRF1; B-cells: MS4A1, SPIB; Plasma-cells: JCHAIN, SDC1, MZB1, TNFRSF17, XBP1; Fibroblasts: COL3A1, COL2A1, MFAP5; proliferating cells: MKI67, TOP2A). T-cell subpopulations were annotated upon careful assessment of expressed genes. particularly, expression of canonical lineage and cell state markers was interrogated (Th1: IFNG, TNF, TBX21, CXCR3; Th17: IL17A, CCL20, RORC, CCR6, KLRB1; central memory T-cell (TCM): CCR7, TCF7, S1PR1, IL7R, SELL; naive T-cells: CCR7, TCF7, LEF1; MAIT: SLC4A10, ME1; cytotoxic lymphocytes (CTL): Granzymes, PRF1; CD4 CTL: CD4, CCL4, CCL5, PRF1; IFN-responsive: ISG15, MX1, RSAD2). Macrophage subpopulations were annotated in an analogous fashion (CD163/LGMN Mp: SPP1, LGMN; pro-inflammatory AMp: CCL3, CCL4, CCL20, TNFAIP6, SOD2; metallothionein AMp: metallothioneins, e.g. MT1G, MT2A, MT1X; IFN-responsive: ISG15, MX1, RSAD2; Foam cells: LDLR, SQLE, HMGCR, MSMO1).
