The fraction of activated dendritic cells (p = 0.031), resting dendritic cells (p = 0.00077), M0 macrophages (p = 0.049), M1 macrophages (p = 0.0079), plasma cells (p = 0.019), CD8 T cells (p = 0.0069), and regulatory T cells (Tregs) (p = 0.023) were significantly different in the situation of lymph node metastasis in thyroid carcinoma (Figure 5B). This evidence concerns the gene CD8A and thyroid gland carcinoma.
