Human NK cell receptor KIR2DS4 detects a conserved bacterial

Web28 mei 2024 · Natural killer (NK) cells are known for their role in defense against viruses and cancer. Their activity is regulated, in part, by killer cell immunoglobulin-like receptors (KIRs) that bind to polymorphic human leukocyte antigen (HLA) class I molecules. The KIR family includes an activation receptor of unknown function, KIR2DS4. WebBoth KIR + and KIR − NK cell subsets exhibit significant potential for cytotoxicity of killing primary AML and ALL blasts. The potent effector function of the KIR − NK cells demonstrates that they can be licensed via receptors other than KIRs.
