Programmed cell death-1 receptor-mediated regulation of TbetNK1.1 innate lymphoid cells within the tumor microenvironment.

Innate lymphoid cells (ILCs) play a key role in tissue-mediated immunity and can be controlled by coreceptor signaling. Here, we define a subset of ILCs that are TbetNK1.1 and are present within the tumor microenvironment (TME).
