Biological function summary
CD161 plays a role in immune system regulation by mediating NK cell and T cell activity. It does not operate as part of a complex but interacts with other cellular receptors to modulate immune responses. For example it serves as an inhibitory receptor often through engagement with its ligand LLT1 to temper immune responses and prevent overactivation. This balance is key to maintaining immune homeostasis and facilitates pathogen clearance while avoiding excessive tissue damage.
Pathways
CD161 is involved in the immune checkpoint pathways and is linked to inflammatory response signaling. These pathways play an important role in the immune system's ability to discern self from non-self determining the intensity and character of the body's defense mechanisms. Other proteins such as CTLA-4 and PD-1 also function within these pathways contributing to the regulation of immune cell activity and preventing autoimmunity.
