[PMID: 33520861 DOI: 10.1007/s40200-020-00569-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Revised: 05/20/2020] [Accepted: 06/10/2020] [Indexed: 12/14/2022]
Abstract
Purpose Type 1 Diabetes (T1D) is a T cell-mediated disease, in which autoimmune destruction of insulin-producing β-cells in pancreatic islets occurs. In recent decades, the role of Killer cell immunoglobulin-like receptor (KIR) gene polymorphisms in susceptibility to T1D has been demonstrated in an increased number of studies. Nonetheless, inconsistency has been observed in the results of performed association studies. To comprehensively clarify the association among KIR gene polymorphisms and the risk of T1D, this meta-analysis on the previously published association studies was carried out via incorporating multiple research. Methods No publication has been recorded from Nov 2017 until July 2020 about the KIR genes and T1D. The PubMed/MEDLINE and Scopus databases were systematically searched up to November 2017 to identify investigations on the impact of the polymorphisms of KIR genes on susceptibility to T1D. The odds ratio (OR) with a 95% confidence interval (95% CI) was calculated. Funnel plot and Egger test were used to assess the publication bias. Thirteen qualified published case-control articles were found for evaluation in this meta-analysis. Results Our results show statistical significance between the genetic variations in the KIR2DL1 (OR = 0.42, 95% CI = 0.23-0.77; P = 0.005), KIR2DL2 (OR = 1.15, 95% CI = 1.00-1.32; P = 0.048), and KIR2DL5 (OR = 0.86, 95% CI = 0.75-0.98; P = 0.03) with susceptibility to T1D. Conclusions This meta-analysis study provides reliable evidence that KIR gene polymorphisms may contribute to T1D risk. KIR 2DL1 and 2DL5 genes might be considered as a protective factor for T1D, while 2DL2 seemed to be a susceptibility factor.

Abstract
The aim of this study was to analyze the genetic profiles of 14 killer cell immunoglobulin-like receptor (KIR) genes and 2 pseudogenes of 124 individuals from Tujia ethnic minority residing in Enshi Tujia and Miao autonomous prefecture of Hubei province of China and investigate the genetic relationships between the Tujia ethnic minority and other reported groups for the first time. Sequence specific primer amplification (PCR-SSP) methods were used to genotype the 14 KIR genes and 2 pseudogenes. The observed carrier frequencies (OF) and the gene frequencies (GF) of the KIR genes were measured. Neighbor-joining (N-J) tree and the principal component analysis (PCA) plot were constructed. All individuals were typed positive for the three framework loci KIR3DL3, 2DL4 and 3DL2, as well as for pseudogene KIR3DP1. The gene frequencies of the other KIR genes ranged from 9% in KIR2DS2 to 98% in KIR2DP1 and KIR3DL1. The present study of the KIR genes may be a powerful tool for enriching the Chinese ethnical gene information resources of the KIR gene pool, as well as for the anthropological research.

Abstract
The killer cell immunoglobulin-like receptor (KIR) gene cluster exhibits extensive allelic and haplotypic diversity that is observed as presence/absence of genes, resulting in expansion and contraction of KIR haplotypes and by allelic variation of individual KIR genes. We report a case of KIR pseudogene 2DP1 and 2DL1 gene absence in members of one family with the children suffering from acute myelogenous leukemia (AML). Killer cell immunoglobulin-like receptor low resolution genotyping was performed by the polymerase chain reaction (PCR)-sequence-specific primers (SSP)/sequence-specific oligonucleotide (SSO) method and haplotype assignment was done by gene content analysis. Both parents and the maternal grandfather, shared the same Cen-B2 KIR haplotype, containing KIR 3DL3, -2DS2, -2DL2 and -3DP1 genes. The second haplotype in the KIR genotype of the mother and grandfather was Tel-A1 with KIR 2DL4 (normal and deleted variant), -3DL1, -22 bp deletion variant of the 2DS4 gene and -3DL2, while the second haplotype in the KIR genotype of the father was Tel-B1 with 2DL4 (normal variant), -3DS1, -2DL5, -2DS5, -2DS1 and 3DL2 genes. Haplotype analysis in all three offsprings revealed that the children inherited the Cen-B2 haplotype with the same gene content but two of the children inherited a deleted variant of the 2DL4 gene, while the third child inherited a normal one. The second haplotype of all three offspring contained KIR 2DL4, -2DL5, -2DS1, -2DS4 (del 22bp variant), -2DS5, -3DL1 and -3DL2 genes, which was the basis of the assumption that there is a hybrid haplotype and that the present 3DL1 gene is a variant of the 3DS1 gene. Due to consanguinity among the ancestors, the results of KIR segregation analysis showed the existence of a very rare KIR genotype in the offspring. The family who is the subject of this case is even more interesting because the father was 10/10 human leukocyte antigen (HLA)-matched to his daughter, all members of the family have the “best” donor KIR-B content and the presence of a rare KIR genotype with KIR 2DP1-2DL1 genes absence.

Abstract
AIM Killer immunoglobulin-like receptors (KIRs) and their interaction with HLA class I ligands have been shown to be associated with Type 1 diabetes mellitus. The aim of our study was to investigate the influence of KIR genes and their HLA-C ligands for susceptibility to Type 1 diabetes in patients from Eastern India. METHODS A total of 135 patients with Type 1 diabetes and 98 healthy subjects from Eastern India were typed for KIR genes and HLA-C ligands using PCR-based genotyping. The frequencies of these genes were compared between patients and controls. RESULTS Comparison of KIR genes between Type 1 diabetes patients and healthy subjects revealed significantly different frequencies of KIRs 2DL2 and 2DS4. The presence of HLA-C1 was negatively associated with disease. The presence of both HLA-C1 and -C2 showed a negative association with Type 1 diabetes, whereas the absence of C1 and presence of C2 was positively associated with disease. Stratification analysis of HLA-C ligands and KIRs showed significant associations between Type 1 diabetes and 2DL2+/C1-, 2DL2-/C1+, 2DL3+/C1+, 2DL3+/C1- and 2DS2+/C1-. CONCLUSIONS Our results suggest that the interaction of KIRs with HLA-C ligands are significant and certain combinations contribute to susceptibility to and protection against Type 1 diabetes.

Abstract
BACKGROUND Killer cell immunoglobulin-like receptors (KIRs) are glycoproteins regulating the response of natural killer (NK) cells and a few sub-sets of T-cells. The KIR gene frequencies and genotype content vary considerably among different ethnic groups. AIM The aim of this study was to analyse KIR gene polymorphism in the population of Vojvodina and to compare it with selected worldwide populations. SUBJECTS AND METHODS The studied sample consists of 134 healthy unrelated individuals, residents of different geographical regions of Vojvodina. DNA samples isolated from peripheral blood leukocytes by the silica-based extraction method were used in reverse PCR-SSO and PCR-SSP technique to detect the presence and absence of KIR genes. RESULTS All 16 KIR genes, a total of 37 different KIR genotypes, were observed in the Vojvodina population with the presence of framework and pseudogenes in all individuals. The neighbour-joining phylogenetic tree shows that the Vojvodina population is in the same cluster with Croatians, Turkish, Russians, Czechs, Irish, Italians, French, Macedonians and Polish. The Vojvodina population shows polymorphism of the KIR gene family present in other European and European-derived populations studied previously. CONCLUSION The present study may serve as a reference for comparisons in further anthropological and disease association studies and also provide more informative data valuable for donor search strategy in haematopoietic stem cell transplantation.

Abstract
The killer immunoglobulin-like receptor (KIR) genes KIR2DL4, KIR3DL2, and KIR3DP1 are present in virtually all humans. KIR2DL4 encodes a receptor present on uterine and decidual natural killer (NK) cells and some peripheral blood NK cells. Its only known ligand is the human leukocyte antigen-G molecule expressed on extravillous trophoblasts, and on tissues in some diseases. KIR3DL2 binds HLA-A*03 and HLA-A*11 as well as HLA-B*27 dimers, and microbial CpG DNA. KIR3DP1 is a pseudogene. During our immunogenetic studies we found two individuals, one from Lower Silesia district in Poland, and another from Western Ukraine, who were reproducibly negative for KIR2DL4 and KIR3DP1 genes, using three different PCR systems. Both individuals displayed very similar genotypes, possessing only KIR3DL3, KIR2DL3, KIR2DP1, KIR2DS1, and probably a rare variant of KIR2DL1. The Pole had also KIR3DL2, which the Ukrainian was apparently lacking. The Lower Silesia has been populated after the Second World War by a remarkable percentage with displaced people from Western Ukraine, which might contribute to genetic similarity of the two individuals described here.

Abstract
Killer cell immunoglobulin like receptor (KIR) is highly polymorphic in genotype, haplotype and allele levels. This study was done to investigate KIR genes frequencies, genotypes and inheritance in Mongolian. Gene-specific PCR amplification was used to identify the presence or absence of 16 KIR loci.KIR genotypes were obtained by a KIR genotypes website. The KIR genes frequencies of Mongolian were compared to 24 different populations around the world. The distribution of haplotype B in Mongolian was higher than that in Mongoloid and less than that in Caucasian. Thirty discovered genotypes and five novel genotypes were identified from 1 to 34 individuals. 37.8% of Mongolian carried KIR haplotype AA.Mongolian was exhibited between North Mongoloid and Caucasus by principal component and genetic tree analysis.

Abstract
West Nile virus (WNV) is a neurotropic, arthropod-borne flavivirus that is maintained in an enzootic cycle between mosquitoes and birds, but can also infect and cause disease in horses and humans. The aim of this study was to examine KIR gene polymorphisms by determining the frequencies of 16 KIR genes and pseudogenes and KIR genotypes in Macedonian patients with West Nile virus infection, and to compare with healthy Macedonians. The studied sample consists Republic of Macedonia, hospitalized at the University Clinic of Infective Diseases between September 2011 and October 2011, and reported through WHO. For KIR genotyping, commercially available PEL-FREEZ KIR genotyping SSP kit (Dynal Biotech, Brown Deer, WI) was used. The population genetics analysis package, Arlequin, was used for analysis of the data. We found that all 16 KIR genes were observed in the studied individuals and framework genes (KIR3DL3, KIR3DP1, KIR2DL4, and KIR3DL2) were present in all individuals. Comparison of KIR frequencies between Macedonian patients with West Nile virus infection and healthy Macedonian population reveals several significant differences in the inhibitory group (KIR2DL2), and in the non inhibitory group (KIR2DS1, KIR2DS2, KIR2DS5, and KIR3DS1). The single most frequent genotypes in the Bx group were genotypes ID71 and ID89 with statistically significant difference compared to healthy Macedonians. Our results suggest that specific KIR genotypes could be connected with West Nile virus infection.

Abstract
Killer cell immunoglobulin-like receptors (KIR) are encoded by highly polymorphic genes that regulate the activation of natural killer (NK) cells and other lymphocyte subsets and likely play key roles in innate and adaptive immunity. Association studies increasingly implicate KIR in disease predisposition and outcome but could be confounded by unknown KIR genetic structure in heterogeneous populations. To examine this, we characterized the diversity of 16 KIR genes in 712 Northern Californians (NC) stratified by self-assigned ethnicities and compared the profiles of KIR polymorphism with other US and global populations using a reference database. Sixty-eight distinct KIR genotypes were characterized: 58 in 457 Caucasians (NCC), 17 in 47 African Americans (NCAA), 21 in 80 Asians (NCA), 20 in 74 Hispanics (NCH), and 18 in 54 "other" ethnicities (NCO). KIR genotype patterns and frequencies in the 4 defined ethnicities were compared with each other and with 34 global populations by phylogenetic analysis. Although there were no population-specific genotypes, the KIR genotype frequency patterns faithfully traced the ancestry of NCC, NCAA, and NCA but not of NCH whose ancestries are known to be more heterogeneous. KIR genotype frequencies can therefore track ethnic ancestries in modern urban populations. Our data emphasize the importance of selecting ethnically matched controls in KIR-based studies to avert spurious associations.

Abstract
Natural killer (NK) cells play an important role in innate immunity, especially in the response to viral infections, such as hepatitis C virus (HCV). Killer cell immunoglobulin-like receptors (KIRs) are the primary receptors of NK cells that mediate innate immunity. KIRs are also involved in acquired immunity, because some KIRs are expressed on the surface of certain subsets of T cells. In this study, the frequency of KIR genes, HLA-C allotypes, and combinations of KIR genes with their HLA-C ligands were evaluated in two different groups of the Korean population: controls and patients with chronic HCV infection. The study population consisted of 147 Korean patients with chronic HCV infection. The frequency of KIR2DS2 in patients with chronic HCV infection was 9.5% which was significantly lower than 19.5% of the control (P < 0.01). However, there were no significant differences in the frequency of other KIR genes, HLA-C allotypes or different combinations of KIR genes with their HLA-C ligands. This study can contribute to the further prospective study with a larger scale, suggesting the assumption that KIR2DS2 might aid in HCV clearance by enhancing both the innate and acquired immune responses of people in Korea.

Abstract
The aim of this study was to analyze Killer Ig-Like Receptor (KIR) gene polymorphisms in Roma people from Republic of Macedonia. The studied sample consists of 103 healthy unrelated individuals, aged 20-45 years. All individuals are of Roma origin, residents of different geographical regions (Gostivar, Skopje, and Kochani). The population genetics analysis package, Arlequin, was used for analysis of the data. We found that all 16 KIR genes were observed in the Roma individuals and framework genes (KIR3DL3, KIR3DP1, KIR- 2DL4, and KIR3DL2) were present in all individuals. The frequencies of other KIR genes were: KIR2DP1 (1), KIR2DL1 (0.961), KIR2DL2 (0.544), KIR2DL3 (0.874), KIR2DL5 (0.311), KIR3DL1 (0.990), KIR- 2DS1 (0.330), KIR2DS2 (0.553), KIR2DS3 (0.359), KIR2DS4 (0.981), KIR2DS5 (0.291), and KIR3DS1 (0.379). The results of tested linkage disequilibrium (LD) among KIR genes demonstrated that KIR genes present a wide range of linkage disequilibrium. The obtained results for KIR genes and genotype frequencies in Macedonian Roma individuals can be used for anthropological comparisons.
