Based on the expression of canonical genes, we identified NK cell, 7 T cell clusters (including γδ T cells, GZMK+ effector memory T cells (Tem), GZMK+ exhausted effector memory T cells (Tex), naïve T cells (Tn), proliferative T cells, regulatory T cells (Treg), and interferon‐stimulated genes (ISG)+ T cells); 5 myeloid cell clusters (including monocyte, macrophage, plasma dendritic cells (DC), conventional DCs and mast cells); thyrocyte, thyroid cancer cells, fibroblasts, and endothelial cells (Figure 5B; Figure S5A, Supporting Information). This evidence concerns the gene GZMK and thyroid gland carcinoma.
