The thyroid cancer cell culture supernatant decreased the expression of the activating receptors NKp46, NKp44, NKp30, and NKG2D in NK cells (Figure 1C; Figure S1A in Supplementary Material) as well as the level of TRAIL, which binds to death receptors expressed by cancer cells. The gene discussed is TNFSF10; the disease is thyroid gland carcinoma.
