IL-1R8 is a checkpoint in NK cells regulating anti-tumour and anti-viral activity

Interleukin-1 receptor 8 (IL-1R8), a negative regulator of the IL-1 family of cytokines, restrains the activity of natural killer (NK) cells, suggesting that IL-1R8 acts as a checkpoint regulator of NK cell activation and that its blockade may be of use in cancer therapy.
