Natural killer (NK) cells specialize in killing virally infected- or tumor cells and are part of the innate immune system. The activational state of NK cells is determined by the balance of incoming activating and inhibitory signals mediated by receptor-ligand binding with the target cell. These receptor-ligand bonds mainly consist of the killer immunoglobulin-like receptors (KIR), which are expressed at the cell surface of NK cells, and their ligands: the highly variable human leukocyte antigen -class I molecules (HLA)...

Cytokine-induced memory-like natural killer (NK) cells differentiate following short-term pre-activation with interleukin (IL)-12, IL-15, and IL-18 and display enhanced effector function in response to cytokines or tumor targets for weeks following the initial pre-activation. Conventional NK cell function is dependent upon a licensing signal, classically delivered by an inhibitory receptor engaging its cognate MHC class I ligand. How licensing status integrates with cytokine-induced memory-like NK cell responses is unknown...

BACKGROUND: Nature killer (NK) cells are the immune system's first line of defense against both viral infections and tumors. Killer cell immunoglobulin-like receptors (KIRs) are associated with susceptibility to different types of cancers. We investigated KIR 2D (L1, L3, L4, S4) and KIR 3DL1 protein expression and their association with survival in non-small cell lung cancer (NSCLC). METHODS: The expression of KIR 2D (L1, L3, L4, S4) (BC032422/ ADQ31987/ NP_002246/ NP_036446, ABCAM) and KIR 3DL1 (AA 1-444, ABCAM) protein was assessed by immunohistochemistry (IHC) in 62 NSCLC patients...

Natural killer (NK) cells control viral infection in part through the interaction between killer cell immunoglobulin-like receptors (KIRs) and their human leukocyte antigen (HLA) ligands. We investigated 504 anti-retroviral (ART)-free Japanese patients chronically infected with HIV-1 and identified two KIR/HLA combinations, KIR2DL2/HLA-C(∗)12:02 and KIR2DL2/HLA-C(∗)14:03, that impact suppression of HIV-1 replication. KIR2DL2(+) NK cells suppressed viral replication in HLA-C(∗)14:03(+) or HLA-C(∗)12:02(+) cells to a significantly greater extent than did KIR2DL2(-) NK cells in vitro...

As an example of optimizing population-specific genotyping assays using a whole-genome sequence reference set, we detail the approach that followed to design the Axiom-NL array which is characterized by an improved imputation backbone based on the Genome of the Netherlands (GoNL) reference sequence and, compared with earlier arrays, a more comprehensive inclusion of SNPs on chromosomes X, Y, and the mitochondria. Common variants on the array were selected to be compatible with the Illumina Psych Array and the Affymetrix UK Biobank Axiom array...

Natural killer (NK) cells are lymphocytes having vital functions in innate and adaptive immunity, as well as placental reproduction. Controlling education and functional activity of human NK cells are various receptors that recognize HLA class I on the surface of tissue cells. Epitopes of polymorphic HLA-A,-B and -C are recognized by equally diverse killer cell immunoglobulin-like receptors (KIR). In addition, a peptide cleaved from the leader sequence of HLA-A,-B or -C must bind to HLA-E for it to become a ligand for the conserved CD94:NKG2A receptor...

The killing activity of natural killer cells is largely regulated by the binding of class I human leukocyte antigen cognate ligands to killer cell immunoglobulin - like receptor proteins. The killer cell immunoglobulin - like receptor gene - complex contains genes that activate and others that inhibit the killing state of natural killer cells depending on the binding of specific human leukocyte antigen cognate ligands. It has been suggested in previous publications that activating human leukocyte antigen/killer - cell immunoglobulin - like receptor complexes are increased in people with autism...

Colorectal cancer is one of the most common types of inflammation-based cancers and is occurred due to growth and spread of cancer cells in colon and/or rectum. Previously genetic association of cell cycle genes, both proto-oncogenes and the tumor suppressors has been proved. But there were few studies about association of immune related genes such as killer-cell immunoglobulin-like receptors (KIRs). Thus we intend to perform a meta-analysis to find the association of different genes of KIR and susceptibility to be affected by colorectal cancer...

BACKGROUND: The interaction between killer immunoglobulin-like receptors (KIRs) and HLA class I regulates natural killer (NK) cell cytotoxicity and function. The impact of NK cell alloreactivity through KIR in liver transplantation remains unelucidated. Since the frequency of HLA-C and KIR genotypes show ethnic differences, we assessed the impact of HLA-C, KIR genotype, or KIR-ligand mismatch on the allograft outcome of Korean liver allografts. METHODS: One hundred eighty-two living donor liver transplant patients were studied...

BACKGROUND: Occurring frequently after solid organ and hematopoietic stem cell transplantation, cytomegalovirus (CMV) replication remains a relevant cause of mortality and morbidity in affected patients. Despite these adverse effects, an increased alloreactivity of natural killer (NK) cells after CMV infection has been assumed, but the underlying physiopathological mechanisms have remained elusive. METHODS: We used serial analyses of NK cells before and after CMV infection in kidney transplant recipients as an in vivo model for CMV primary infection to explore the imprint of CMV infection using every patient as their own control: We analyzed NK cell phenotype and function in 47 CMV seronegative recipients of CMV seropositive kidney grafts, who developed CMV primary infection posttransplant...

The present study evaluated the ameliorative effects of Trametes orientalis polysaccharide (TOP-2) against cyclophosphamide (CP) induced toxicity in mice. Intraperitoneal administration of TOP-2 not only effectively increased the thymus, spleen, heart, liver, and kidney indices, but also significantly enhanced the phagocytic activities of macrophages and splenocyte proliferation, dose-dependently. The lowered nitric oxide level of macrophages after CP treatment was elevated by TOP-2 administration. Impaired splenic natural killer cells and cytotoxic T lymphocytes activities were remarkably enhanced by TOP-2...

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...

BACKGROUND: Natural Killer (NK) cell alloreactivity is favored after double umbilical cord blood transplantation (dUCBT) in which cord blood (UCB) units and patients are often Human Leucocyte Antigen (HLA) class I mismatched. Generally, only 1 UCB unit persists after dUCBT. We hypothesize, that NK cell alloreactivity mediated by Killer cell Immunoglobulin-like Receptor (KIR) - HLA interactions may explain the dominance of 1UCB unit over the other after dUCBT. METHODS: We investigated the impact of KIR NK cell alloreactivities on the dominance of 1 full UCB unit in 50 dUCBT...

Immunological molecules are implicated in inflammatory disorders, including IBD [CD and UC]. A further group of genetically variable proteins involved in immune function are killer cell immunoglobulin-like receptors (KIRs). These are expressed by NK cells and certain T lymphocytes where they regulate specificity and function by interaction with HLA Class I molecules. KIRs may either be inhibitory or activating and are polymorphic both in terms of alleles and haplotype gene content. Genetic associations of activating KIRs with certain autoimmune and inflammatory diseases have been demonstrated...

Successful pregnancy relies on the accurate regulation of the maternal-fetal immune system. Without enough tolerance in the uterine microenvironment, the mother and the hemiallogeneic fetus could not peacefully coexist. T cell immunoglobulin and mucin domain (Tim)-3 is a molecule originally regarded as to be expressed on terminally differentiated IFN-γ expressing CD4(+) T cells (Th1). The engagement of Tim-3 with its ligand, galectin-9 (Gal-9) could induce the exhaustion or apoptosis of effector T cells, and thus might regulate the tolerance...

BACKGROUND: The Hyper-immunoglobulin M syndromes (HIGM) are a heterogeneous group of genetic disorders, which have been rarely reported to be associated with growth hormone deficiency (GHD). METHODS AND RESULTS: A nine-year-old girl with recurrent urinary tract infections, diarrhoea, sinopulmonary infections, and failure to thrive since the age of six months had normal CD3+, CD4+, CD8+T lymphocytes, and CD19+B lymphocytes and natural killer (NK) cells, but extremely elevated IgM and significantly decreased IgG and IgA...

Killer-cell immunoglobulin-like receptors (KIRs) are components of two fundamental biological systems essential for human health and survival. Firstly, they contribute to host immune response, both innate and adaptive, through their expression by natural killer (NK) cells and T cells. Secondly, KIR play a key role in regulating placentation, and hence reproductive success. Analogous to the diversity of their HLA class I ligands, KIR are extremely polymorphic. In this review, we describe recent developments, fuelled by methodological advances, which are helping to decipher the KIR system in terms of haplotypes, polymorphisms, expression patterns and their ligand interactions...

Hepatitis C virus (HCV) infection remains one of the most important blood-borne diseases worldwide with about 130-170 million people chronically infected with hepatitis C virus, and more than 350 000 people die from hepatitis C-related liver diseases each year. Infection with HCV becomes chronic in approximately 80% of cases, while in up to 20% of cases hepatitis C virus is cleared from the human organism. Chronic infections of hepatitis C often leads to the end-stage liver diseases such as cirrhosis and hepatocellular carcinoma...

Anti-aquaporin-4 (AQP4) autoantibody plays a key role in the pathogenesis of neuromyelitis optica (NMO). Studies have shown increased relapse rates in patients with NMO during pregnancy and postpartum. High estrogen levels during pregnancy can increase activation-induced cytidine deaminase expression, which is responsible for immunoglobulin production. Additionally, sex hormones may influence antibody glycosylation, with effects on antibody function. Estrogen decreases apoptosis of self-reactive B cells, through upregulation of antiapoptotic molecules...
