T cells can halt development of skin cancer, Yale researchers find
...inoma," Girardi said. The researchers showed that gamma
delta T cells carry out their anti-cancer function by expressing a protein called NKG2d, which can focus in on a molecule called Rae-1, which is expressed by tumor cells. Once Rae-1 is engaged by NKG2d, the gamma-delta T cells are then able to kill t...
