The impact of KIR2DS4 gene on clinical outcome after hematopoietic stem cell transplantation. Hum Immunol 2016; 78:95-102. [PMID: 27998801 DOI: 10.1016/j.humimm.2016.11.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2016] [Revised: 10/10/2016] [Accepted: 11/01/2016] [Indexed: 10/20/2022]
Abstract
Killer cell immunoglobulin-like receptors (KIR) are a family of inhibitory/activating receptors expressed on NK cells. Interactions of KIR receptors with KIR ligands have been shown to modify hematopoietic stem cell transplantation (HSCT) outcome. The aim of this research was to determine the KIR2DS4 allele variants distribution among 111 patients with different hematological malignancy who underwent HSCT and their donors, and to evaluate KIR2DS4 alleles' impact on HSCT outcome. The KIR gene frequency analysis showed a significantly higher incidence of full-length KIR2DS4 alleles among patients. The impact of KIR2DS4 alleles on transplantation outcomes revealed that donors' full-length KIR2DS4 alleles is associated with lower overall survival rates, higher risk of GVHD and higher relapse incidence. The expression of full-length KIR2DS4 allele variants may contribute to a worse clinical outcome after HSCT. KIR typing for KIR2DS4 could be used as an additional criterion for selecting suitable donors in cases when more than one HLA identical donor is identified for a specific patient.

Abstract
Killer cell immunoglobulin-like receptor (KIR) genes are variably distributed among populations from distinct geographic areas and ethnic origins. We describe, for the first time, KIR gene diversity in 152 unrelated and healthy Drung individuals, as measured by sequence-specific polymerase chain reaction. All 16 known KIR genes were detected. Of these, the framework genes KIR2DL4, 3DL2, 3DL3, and 3DP1 were present in all individuals as expected, along with the non-framework genes KIR2DL1, 2DL3, and 2DP1. In contrast, KIR2DL2, 2DS2, and 2DS5 were unusually rare, suggesting that KIR gene distribution was relatively concentrated. Ten different KIR genotypes were found, of which the most common consisted of nine genes (KIR2DL1, 2DL3, 2DL4, 2DS4, 3DL1, 3DL2, 3DL3, 2DP1, and 3DP1) and accounted for 66.4% of participants. There were eight different haplotypes present, of which the A haplotype was the most common (81.9%). Principal components and dendrogram analysis confirmed that the Drung Chinese are most closely related to the Japanese, the Zhejiang Han, and the Yunnan Han. In conclusion, distinctive frequencies of KIR genes, haplotypes, and genotypes are observed in Chinese Drung.

Abstract
Killer-cell immunoglobulin-like receptors (KIRs) play an important role in natural killer (NK) cell regulation. Interaction of KIRs with human leukocyte antigen (HLA) class I molecules can transmit signals to regulate the function of NK cells. In this study, the diversities of KIR genes and their ligands in 500 Thai blood donors were investigated. The coexistence of inhibitory KIRs (iKIR), activating KIRs (aKIR) and their ligands in the same individuals were also analyzed. Overall, 36 KIR genotypes were identified. The most common genotype was genotype AA1 (40.8%). All individuals carried at least one iKIR-HLA pair whereas 18% of the individuals lacked aKIR-HLA pair. The most common compound KIR-HLA profile was the presence of 3 iKIR-HLA pairs with 1 aKIR-HLA pair (21.4%). The most common compound gene profile of KIR-HLA pairs was the combined presence of KIR2DL3-C1, 3DL1-Bw4, 3DL2-A3/A11 and the full length KIR2DS4-its ligands (8%). This study provided a comprehensive analysis of the KIR-HLA profiles in Thai blood donors in regards to KIR genotypes, HLA ligands, KIR-HLA ligand pairs and compound gene profiles of both iKIRs and aKIRs and their ligands. These findings will be useful as baseline information for further studies in the associations of KIR genes and various diseases.

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
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.
