CD4 and neoplasm: Specifically, we identified macrophages (7 cell clusters), MDSCs (2 cell clusters), granulocytes (2 cell clusters), CD4+ T cells (1 cell cluster), CD8+ T cells (2 cell clusters), natural killer (NK) cells (1 cell cluster), B cells (2 cell clusters), dendritic cells (DCs, 2 cell clusters), plasmacytoid dendritic cells (pDCs, 1 cell cluster), conventional dendritic cells (cDCs, 1 cell cluster), fibroblasts (1 cell cluster) and tumour cells (1 cell cluster) (Supplementary Fig. 5a).
