Abstract
Killer cell immunoglobulin-like receptors (KIRs) are cell surface receptors on natural killer (NK) cells and subsets of T cells. The interaction between KIRs and their cognate ligands (Human leukocyte antigen class I molecules, HLA class I) modulates the immune response of NK cells, in particular through clearance of virus-infected cells. Here, we investigated the effect of KIRs and HLA ligands on dengue infections and disease severity. The KIRs and HLA ligands were identified in 235 healthy controls (HC) and 253 dengue patients (DEN) using polymerase chain reaction with sequence specific primer (PCR-SSP); moreover, DEN was classified to 100 dengue fever (DF) and 153 dengue haemorrhagic fever (DHF). Risks were expressed as odds ratios (ORs) and 95% confidence intervals (CIs) with significance set at a two-tailed P value of < 0.05. The Bonferroni correction was applied for multiple comparisons. Twelve significant associations were observed in dengue infections and disease severity; however, two outcomes survived after the Bonferroni correction. Of these, HLA-A11 was associated with an increased risk to develop dengue disease (OR 2.41, 95% CI 1.62-3.60, Pc = 0.004), while KIR3DS1+ Bw4 was a protective genotype to developing DHF (OR 0.28, 95% CI 0.16-0.48, Pc < 0.001). This study revealed an important role of KIR and HLA ligands in innate immune responses to dengue viral infections and, in particular, their effect on clinical outcomes and disease severity.

Polymorphisms of killer immunoglobulin-like receptors (KIRs) and HLA ligands in northeastern Thais. Immunogenetics 2013; 65:645-53. [PMID: 23812166 DOI: 10.1007/s00251-013-0716-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2013] [Accepted: 06/10/2013] [Indexed: 10/26/2022]
Abstract
Killer cell immunoglobulin-like receptors (KIRs) are cell surface receptors on natural killer (NK) cells and subsets of T cells. The functions of NK cells are partly regulated by interactions between KIRs and HLA ligands on target cells. In this study, the presence or absence of 17 KIR genes and their known HLA ligands have been investigated in 235 unrelated individuals living in northeastern Thailand (NET). Subtypes of KIR2DS4 including full length (KIR2DS4F) and deleted forms (KIR2DS4D) have also been determined. Framework genes (KIR2DL4, 3DL2, 3DL3, and 3DP1) were found in all individuals and KIR genes belonging to the A haplotype (KIR2DL1, 2DL3, 3DL1, and 2DS4) were present in more than 90% of NET. KIR2DS4D (61.7%) was more common than KIR2DS4F (52.8%). A total of 33 different KIR genotypes were observed. Of these, three new genotypes were identified. The most common genotype (AA) was observed in 35.7% of NET, and HLA-C alleles bearing the C1 epitope (HLA-C1) had the highest frequency (97%). All individuals had at least one inhibitory KIR and its corresponding HLA ligand; 40.9% of NET had three pairs of receptor-ligand combinations, and 18.3% had all three receptor-ligand combinations of KIR2DL3+C1, 3DL1+Bw4, and 3DL2+A11. Surprisingly, the patterns of KIR gene frequencies in NET are more similar to those of Caucasians than Japanese, Korean, and Chinese. This is the first report on complete analysis of KIR and known HLA ligands in Thais. These data provide basic knowledge on KIR for further studies on disease associations and transplantation in northeastern Thais.
