A relevant example is the fairly recent evolution of entirely different types of NK cell receptors in mice and humans, who last shared a common ancestor around 65 million years ago; mouse NK cells ...
The polymorphic nature of KIRs and their ligands adds a layer of complexity to NK cell interactions with tumor cells. Moreover, other inhibitory receptors like CD94/NKG2A, PD-1, TIGIT, and TIM-3 ...
which are inhibitory cell surface receptors that have the ability to block antitumor immunity, have an impact on this exhaustion. NK cells’ metabolism, proliferation, survival, and cytotoxic ...
