What are Killer Cell Immunoglobulin Like Receptors (KIRs)?
Killer cell immunoglobulin like receptors (KIRs) are a family of receptors expressed on the surface of natural killer (NK) cells and some T cells. These receptors play critical roles in the immune response by regulating the activity of NK cells. KIRs are pivotal in distinguishing between healthy and unhealthy cells, including those that are infected or cancerous.
