Background: KIR2DL1/CD158a

KIRDL2, also known as CD158a, belongs to the killer-cell immunoglobulin-like receptor (KIR) gene family expressed by natural killer (NK) cells and functions in inhibitory signaling (1,2). The KIR genes consisting of 15 gene loci and two pseudogenes are located on chromosome 19 and segregated into halptype A or B depending on gene composition (1). Human KIR2DL1 belongs to haplotype A and is synthesized as a protein of 348 amino acids (aa) in length with a theoretical molecular weight (MW) of 38.5 kDa (3). The KIR2DL1 protein consists of two extracellular immunoglobulin (Ig)-like C2 domains, a transmembrane domain, and a long cytoplasmic tail containing an immunoreceptor tyrosine-based inhibitory motif (ITIM) (1,3). KIR2DL1 binds human leukocyte antigen (HLA) alleles with the C2 supratype, resulting in an inhibitory immune response and suppression of NK cell activity to target cells (1,2). KIR2DL1 has been shown to be a potential clinical biomarker for diseases related to suppressed NK cell function (4). An increase in inhibitory receptors such as KIR2DL1/CD158a is observed in certain pathologies like endometriosis and multiple myeloma (4,5). Therapeutic inhibition of KIR2DL1 may be a potential treatment option for endometriosis patients (5). Additionally, blocking of KIR2DL1 combined with rituximab, and anti-CD20 monoclonal antibody, has shown increased NK cell cytotoxicity than just the antibody itself (5).
