Uniform manifold approximation and projection (UMAP) analysis of total combined tumor-infiltrating immune cells showed the formation of nine-cell clusters: B cells, CD8 T cells, DCs, mast cells, granulocytes, monocytes/TAMs, natural killer (NK) cells, T helper (Th) cells, and CD4 regulatory T (Treg) cells (Figures 2B and S2A). The gene discussed is CD4; the disease is neoplasm.
