There were fewer B cells, tumor-infiltrating lymphocytes (TIL), CD8+ T cells, T helper cell 1 (Th1 cells), T helper cell 2 (Th2 cells), follicular helper T cell (Tfh), natural killer (NK) cells, dendritic cells (DCs), and neutrophils in the cluster 0 high-score group than in the cluster 0 low-score group (Figure S11C). The gene discussed is CD8A; the disease is neoplasm.
