    Background

    Killer cell immunoglobulin-like receptors (KIRs) are type 1 transmembrane glycoproteins expressed by natural killer (NK) cells and subsets of CD4, CD8, and γδ T cells (1-5). Analogous to the diversity of their human leukocyte antigen class I (HLA class I) ligands, the KIR genes are polymorphic and the content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (6,7). The KIR proteins are characterized by the number of extracellular immunoglobulin-superfamily domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain (8-10). KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM) (10), while KIR proteins with the short cytoplasmic domain lack an ITIM and instead transduce activating signals (11,12). KIR proteins play an important role in the regulation of the immune response. Combinations of KIR and HLA class I variants influence susceptibility to autoimmunity and infectious disease, as well as outcomes of haematopoietic stem cell transplantation (12-14).

    KIR2DL2 and KIR2DL3, also referred to as CD158b1 and CD158b2, respectively, regulate NK cells by interacting with the human leukocyte antigen-C1 (HLA-C1) group of molecules (15). Upon receptor ligand interaction, KIR2DL2 and KIR2DL3 inhibit the activity of NK cells thus preventing target cell lysis (16-18).
