Abstract
Ulcerative colitis (UC) is a chronic inflammatory illness affecting the colon and rectum, with current treatment methods being unable to meet the clinical needs of ulcerative colitis patients. Although nanomedicines are recognized as promising anti-inflammatory medicines, their clinical application is limited by their high cost and unpredictable safety risks. This study reveals that two natural phytochemicals, berberine (BBR) and hesperetin (HST), self-assemble directly to form binary carrier-free multi-functional spherical nanoparticles (BBR-HST NPs) through noncovalent bonds involving electrostatic interactions, π-π stacking, and hydrogen bonding. Because of their synergistic anti-inflammatory activity, berberine-hesperetin nanoparticles (BBR-HST NPs) exhibit significantly better therapeutic effects on UC and inhibitory effects on inflammation than BBR and HST at the same dose by regulating the immune microenvironment and repairing the damaged intestinal barrier. Furthermore, BBR-HST NPs exhibit good biocompatibility and biosafety. Thus, this study proves the potential of novel natural anti-inflammatory nanoparticles as therapeutic agents for UC, which could promote the progress of drug development for UC and eventually benefit patients who suffering from it.

Abstract
Interactions of killer cell immunoglobin-like receptors (KIR) with human leukocyte antigens (HLA) class I regulate effector functions of key cytotoxic cells of innate and adaptive immunity. The extreme diversity of this interaction is genetically determined, having evolved in the ever-changing environment of pathogen exposure. Diversity of KIR and HLA genes is further facilitated by their independent segregation on separate chromosomes. That fetal implantation relies on many of the same types of immune cells as infection control places certain constraints on the evolution of KIR interactions with HLA. Consequently, specific inherited combinations of receptors and ligands may predispose to specific immune-mediated diseases, including autoimmunity. Combinatorial diversity of KIR and HLA class I can also differentiate success rates of immunotherapy directed to these diseases. Progress toward both etiopathology and predicting response to therapy is being achieved through detailed characterization of the extent and consequences of the combinatorial diversity of KIR and HLA. Achieving these goals is more tractable with the development of integrated analyses of molecular evolution, function, and pathology that will establish guidelines for understanding and managing risks. Here, we present what is known about the coevolution of KIR with HLA class I and the impact of their complexity on immune function and homeostasis.

Abstract
Genetic studies have illustrated that killer cell immunoglobulin-like receptor (KIR) genes could participate in various autoimmune disorders. We aimed to clarify the role of KIR genes, HLA ligands, HLA-KIR interactions, and their genotypes in inflammatory bowel disease (IBD) susceptibility. The study population was composed of 183 IBD subjects, comprising 100 ulcerative colitis (UC) patients, 83 Crohn's disease (CD) patients, and 274 healthy subjects. Polymerase chain reaction with sequence-specific primers (PCR-SSP) was used to evaluate the absence or presence of the 15 KIR genes, 5 HLA class I ligands, and 2 pseudogenes. We did not find any significant difference in allele frequency of KIRs and pseudogenes between IBD patients and healthy controls. In the case of HLA genes, there was a significant difference in HLA-B-Bw4Thr80 frequency between UC patients and healthy controls (P = 0.03, OR = 0.06, 95%CI = 0.008-0.4). Furthermore, we found a significant difference in HLA-C1Asn80 frequency between CD patients and healthy controls (P = 0.04, OR = 0.49, 95% CI = 0.3-0.8). In the full-array combination of KIR genes, there was no significant frequency difference between UC patients and healthy controls, while two KIR genotypes showed a significant susceptible association with CD. Our data do not support a strong role of NK cells in IBD susceptibility, but it does not rule out a role for KIR variability in IBD patients. However, there are some protective associations such as Bw4 alleles; these associations may be due to the interaction of the alleles to TCRs rather than KIRs.

Abstract
Background Killer-cell Immunoglobulin-like Receptor (KIR) genes encode receptors, which are mainly expressed on, and control functional activities of, Natural Killer (NK) cells. There exist six distinct activating KIR genes in humans, who differ from one another with respect to the repertoire of these genes. Because activated NK cells can potentially cause tissue destruction, we hypothesized that variation in the inherited activating KIR genes in humans is associated with their innate susceptibility/resistance to developing Crohn disease (CD). Methods We performed case control studies on three independent Canadian CD patient cohorts (all of the Western European descent): two comprising children (Montreal having 193 cases and 245 controls, and Ottawa having 93 cases and 120 controls) and the third one comprising predominantly adults (Winnipeg having 164 cases and 200 controls). We genotyped cases and controls for activating KIR genes by PCR with gene-specific primers and investigated associations between the genes and cases using unconditional logistic regression. Results We observed strong associations between all the six KIR genes and CD in Ottawa children, with the strongest risk observed for the KIR2DS1 (p = 1.7 x10-10). Associations between all but the KIR2DS2 were replicated in the Montreal cohort with the strongest association evident for the KIR2DS5 (8.0 x 10−10). Similarly associations between five genes were observed in the adult Winnipeg cohort. In this cohort, strongest associations were evident with the KIR2DS5 (8.75 x 10−8). An overall analysis for all cohorts showed strong associations with four of the genes, with the strongest association evident for the KIR2DS5 (p = 1.35 x 10−17). In the combined analysis for four KIR genes, individuals carrying one or more of the KIR genes were at significantly higher risks for acquiring CD (p = 3.5 x 10−34). Conclusions Activating KIR genes are associated with risk for developing CD in both children and adults.

Abstract
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is a complex chronic inflammatory condition of the human gut of unknown causes. Traditionally, dysregulated adaptive immune responses are thought to play a major role; however, accumulating evidence suggests that innate immunity also contributes to this process. Innate lymphoid cells (ILCs) are recently identified important components of innate immunity. They have critical roles in immunity, tissue development and remodeling. Numerous researchers have linked ILCs to the pathogenesis of IBD. In this review, we describe recent progress in our understanding about the phenotype and function alterations of ILCs as well as its interactions with other key mucosal cells in the gut of IBD patients. A better delineation of the ILCs' behavior in the human intestine will contribute to our understanding of ILCs biology and provide valuable insights for potential therapeutic target selection for IBD patients.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic inflammatory disease, which involves the gut and comprises of Crohn's disease (CD) and ulcerative colitis (UC). Immune cells, including natural killer (NK) cells, play an important role in the pathogenesis of the disease. Killer immunoglobulin-like receptors (KIRs) are NK cell surface receptors, which ligate to the class I major histocompatibility complex (MHC) and have inhibitory or activating effects on the NK cells. The aim of this study was to perform a meta-analysis of the six studies evaluating the association in the polymorphisms of these KIR genes and the IBD risk (4 UC and 5 CD studies). METHODS A systematic search was conducted in the electronic databases to find all the studies on the KIR gene polymorphism in IBD patients prior to December 2017. The odds ratio (OR) and 95% confidence interval (CI) were used to find any association between KIR gene polymorphisms and the IBD risk. RESULTS Following extraction of the data from the studies, which were screened by inclusion and exclusion criteria, collectively 432 patients and 886 controls for UC and 1677 patients and 1308 controls for CD were included in the meta-analysis. The statistical evaluation demonstrated positive associations between 2DL5 (OR=1.31, 95% CI=1.01-1.69) and 2DS1 (OR=1.33, 95% CI=1.01-1.76) members of KIR genes and UC risk, as well a negative association between 2DS3 gene and CD risk was detected (OR=0.74, 95% CI=0.60-0.90). CONCLUSIONS There are positive associations between 2DL5 and 2DS1 members of KIR genes and UC risk and a negative association between 2DS3 and CD risk.

Abstract
Inflammatory bowel disease (IBD) consists of ulcerative colitis (UC) and Crohn’s disease (CD). Natural killer cell responses play a crucial role in autoimmune disease through innate immunity, in which killer cell immunoglobulin-like receptors (KIRs) are closely involved. Although the genetic combination of KIRs with their specific HLA class I ligands has been associated with IBD in Caucasians, such KIR-HLA receptor-ligand combinations are not fully understood in the Japanese. We investigated 14 KIR genes along with HLA-Bw and -C ligands in 90 patients with UC and 50 patients with CD and compared them with the characteristics of 325 healthy control subjects. The frequency of HLA-Bw4 was significantly increased in patients with UC (P = 1.3 × 10−6; odds ratio [OR] = 3.39) and CD (P = 0.0065; OR = 2.32) versus controls. The UC group had a significantly higher frequency of KIR2DS3 (P = 0.024; OR = 1.94) and lower frequency of KIR2DS4 (P = 0.019; OR = 0.40) and KIR2DL1-HLA-C2 (P = 0.035; OR = 0.47). The Tel-A/B haplotype was significantly decreased in UC patients (P = 0.0056; OR = 0.49). The frequency of KIR3DL1-HLA-Bw4 was significantly higher in patients with UC (P = 4.3 × 10−6; OR = 3.12) and CD (P = 0.0067; OR = 2.30). In conclusion, HLA-Bw4 and KIR-HLA pairs may play an important role in the genetic susceptibility to IBD in the Japanese.

Abstract
Immunological molecules are implicated in inflammatory disorders, including inflammatory bowel disease (IBD; Crohn disease [CD] and ulcerative colitis [UC]). Killer cell immunoglobulin-like receptors (KIRs) are also genetically variable proteins involved in immune function. They are expressed by NK cells and certain T lymphocytes, regulate specificity and function by interaction with HLA Class I molecules, may be either inhibitory or activating and are polymorphic both in terms of alleles and haplotype gene content. Genetic associations between activating KIRs and certain autoimmune and inflammatory diseases have been reported; however, a possible association between KIR and IBD remains unclear. The aim of this study was to determine the relationship between KIR repertoire and IBD pathologies in a Spanish cohort. KIR variability was analyzed using PCR-sequence specific oligonucleotide probes (SSOP). Inhibitory KIR2DL5 was found more frequently in UC and IBD patient groups than in healthy controls (P = 0.028 and P = 0.01, respectively), as was activating KIR2DS1 (P = 0.02, Pc > 0.05, UC vs. Controls; P = 0.001, Pc = 0.01, IBD vs Controls; P = 0.01, Pc > 0.05, Controls vs CR), KIR2DS5 (P = 0.0028, Pc = 0.04, Controls vs UC; P = 0.0001, Pc = 0.0017, Controls vs IBD; P = 0.01, Pc > 0.05, Controls vs CD) and KIR3DS1 (P = 0.012, Pc > 0.05, Controls vs IBD). Our data suggest that imbalance between activating and inhibitory KIR may partially explain the different pathogeneses of these IBDs and that there is a hypothetical role for the telomeric B region (which contains both KIR2DS5 and KIR2DS1) in these diseases.

Reduced frequency of two activating KIR genes in patients with sepsis. Hum Immunol 2017; 78:363-369.

Abstract
Natural killer (NK) cell activity is regulated by activating and inhibitory signals transduced by killer cell immunoglobulin-like receptors (KIR). Diversity in KIR gene repertoire among individuals may affect disease outcome. Sepsis development and severity may be influenced by genetic factors affecting the immune response. Here, we examined sixteen KIR genes and their human leucocyte antigen (HLA) class I ligands in critical patients, aiming to identify patterns that could be associated with sepsis. Male and female patients (ages ranging between 14 and 94years-old) were included. DNA samples from 211 patients with sepsis and 60 controls (critical care patients with no sepsis) collected between 2004 and 2010 were included and genotyped for KIR genes using the polymerase chain reaction method with sequence-specific oligonucleotide (PCR-SSO), and for HLA genes using the polymerase chain reaction method with sequence-specific primers (PCR-SSP). The frequencies of activating KIR2DS1 and KIR3DS1 in sepsis patients when compared to controls were 41.23% versus 55.00% and 36.49% versus 51.67% (p=0.077 and 0.037 respectively before Bonferroni correction). These results indicate that activating KIR genes 2DS1 and 3DS1 may more prevalent in critical patients without sepsis than in patients with sepsis, suggesting a potential protective role of activating KIR genes in sepsis.

Abstract
NK cells, which contribute to immune defense against certain viral infections and neoplasia, are emerging as modifiers of chronic immunologic diseases including transplant rejection and autoimmune diseases. Immunobiology and genetic studies have implicated NK cells as a modifier of Crohn's disease, a condition often treated with thiopurine agents such as 6-mercaptopurine (6-MP). Here, we demonstrate that thiopurines mediate NK cell apoptosis via a caspase 3 and 9 inclusive pathway, and that this process is triggered by thiopurine-mediated inhibition of Rac1. We also show that CD patients in clinical remission maintained on 6-MP have decreased NK cell Rac1 activity, and decreased NK cell numbers in their intestinal biopsies. These observations suggest that thiopurine targeting of NK cells may be a previously unappreciated therapeutic action of these agents in IBD.

Abstract
BACKGROUND A dysregulated mucosal immune response to the intestinal environment in a genetically susceptible host is hypothesized to be critical to the pathogenesis of Crohn's disease (CD). Therefore, we examined CD-susceptibility genes involved in the immune response through a genome-wide association study and consecutive genotyping of human leukocyte antigens (HLAs) and killer cell immunoglobulin-like receptors. METHODS An initial genome-wide association study was performed with 275 CD patients and 2369 controls from a Korean population. To validate the loci identified in the genome-wide association study, replication genotyping was performed in a different cohort of 242 CD patients and 1066 controls. Finally, high-resolution genotyping of HLA and killer cell immunoglobulin-like receptor was performed. RESULTS Four susceptibility loci, a promoter region in tumor necrosis factor (ligand) superfamily member (TNFSF15) and 3 independent regions in HLAs, showed significant associations with CD. Among them, rs114985235 in the intergenic region between HLA-B and HLA-C showed the strongest association, with an increased risk of CD (P = 8.71 × 10; odds ratio, 2.25). HLA typing in this region showed HLA-C*01 to be responsible for the association of CD among 43 HLA-B and HLA-C genotypes identified in the Korean population. However, the interaction of HLA-C with killer cell immunoglobulin-like receptor had little effect on the development of CD. CONCLUSIONS We newly identified HLA-C*01 as a prominent CD-susceptibility HLA allotype in the Korean population. In addition, these results confirm that genetic variations in immune response genes, such as HLAs and TNFSF15, are important host factors for the pathogenesis of CD.

Abstract
We aimed to analyze the possible association of KIR/HLA-C genotypes with the susceptibility to Crohn's disease (CD) in a Spanish population. A total of 125 patients with CD and 339 healthy controls were selected for this study. KIR and HLA-C typing were developed by sequence-specific oligonucleotide probing. We found that the centromeric A/A genotype and HLA-C1 combination was significantly increased in CD patients (P<10(-3)). The KIR2DL3/2DL3 genotype was significantly increased in CD patients (P<0.0005). Moreover, we also observed a highly significant increase of KIR2DL3-HLA-C1 homozygosis in CD patients (P<0.0005). Our results confirm the relevance of the KIR2DL2/KIR2DL3 genes and their interaction with HLA-C to CD. We show that the contribution of the KIR genes to CD susceptibility extends beyond the association with individual KIRs, with an imbalance between activating and inhibitory KIR genes seeming to influence the susceptibility to CD.

PLoS One 2014; 9:e110015.

Abstract
The Ly49E NK receptor is a unique inhibitory receptor, presenting with a high degree of conservation among mouse strains and expression on both NK cells and intraepithelial-localised T cells. Amongst intraepithelial-localised T cells, the Ly49E receptor is abundantly expressed on CD8αα-expressing innate-like intestinal intraepithelial lymphocytes (iIELs), which contribute to front-line defense at the mucosal barrier. Inflammatory bowel diseases (IBDs), encompassing Crohn's disease and ulcerative colitis, have previously been suggested to have an autoreactive origin and to evolve from a dysbalance between regulatory and effector functions in the intestinal immune system. Here, we made use of Ly49E-deficient mice to characterize the role of Ly49E receptor expression on CD8αα-expressing iIELs in the development and progression of IBD. For this purpose we used the dextran sodium sulphate (DSS)- and trinitrobenzenesulfonic-acid (TNBS)-induced colitis models, and the TNFΔARE ileitis model. We show that Ly49E is expressed on a high proportion of CD8αα-positive iIELs, with higher expression in the colon as compared to the small intestine. However, Ly49E expression on small intestinal and colonic iIELs does not influence the development or progression of inflammatory bowel diseases.

Abstract
NK cells are innate immune cells known for their cytolytic activities toward tumors and infections. They are capable of expressing diverse killer Ig-like receptors (KIRs), and KIRs are implicated in susceptibility to Crohn's disease (CD), a chronic intestinal inflammatory disease. However, the cellular mechanism of this genetic contribution is unknown. In this study, we show that the "licensing" of NK cells, determined by the presence of KIR2DL3 and homozygous HLA-C1 in host genome, results in their cytokine reprogramming, which permits them to promote CD4(+) T cell activation and Th17 differentiation ex vivo. Microfluidic analysis of thousands of NK single cells and bulk secretions established that licensed NK cells are more polarized to proinflammatory cytokine production than unlicensed NK cells, including production of IFN-γ, TNF-α, CCL-5, and MIP-1β. Cytokines produced by licensed NK augmented CD4(+) T cell proliferation and IL-17A/IL-22 production. Ab blocking indicated a primary role for IFN-γ, TNF-α, and IL-6 in the augmented T cell-proliferative response. In conclusion, NK licensing mediated by KIR2DL2/3 and HLA-C1 elicits a novel NK cytokine program that activates and induces proinflammatory CD4(+) T cells, thereby providing a potential biologic mechanism for KIR-associated susceptibility to CD and other chronic inflammatory diseases.

Abstract
NK cell effector function is regulated by a range of activating and inhibitory receptors, and many of their known ligands are MHC class I molecules. Human NK receptors encoded by the Killer immunoglobulin-like receptor (KIR) gene family recognize polymorphic HLA-C as well as some HLA-A and HLA-B molecules. KIRs are expressed by uterine NK (uNK) cells, which are distinctive NK cells directly in contact with the invading fetal placental cells that transform the uterine arteries during the first trimester. Trophoblast cells express both maternal and paternal HLA-C allotypes and can therefore potentially interact with KIRs expressed by uNK. Therefore, allorecognition of paternal HLA-C by maternal KIR might influence trophoblast invasion and vascular remodeling, with subsequent effects on placental development and the outcome of pregnancy. We discuss here the studies relating to KIR/HLA-C interactions with an emphasis on how these function during pregnancy to regulate placentation.

Abstract
The identification of patients who will respond to anti-tumor necrosis factor alpha (anti-TNF-α) therapy will improve the efficacy, safety, and economic impact of these agents. We investigated whether killer cell immunoglobulin-like receptor (KIR) genes are related to response to anti-TNF-α therapy in patients with rheumatoid arthritis (RA). Sixty-four RA patients and 100 healthy controls were genotyped for 16 KIR genes and human leukocyte antigen-C (HLA-C) group 1/2 using polymerase chain reaction sequence-specific oligonucleotide probes (PCR-SSOP). Each patient received anti-TNF-α therapy (adalimumab, etanercept, or infliximab), and clinical responses were evaluated after 3 months using the disease activity score in 28 joints (DAS28). We investigated the correlations between the carriership of KIR genes, HLA-C group 1/2 genes, and clinical data with response to therapy. Patients responding to therapy showed a significantly higher frequency of KIR2DS2/KIR2DL2 (67.7% R vs. 33.3% NR; P = 0.012). A positive clinical outcome was associated with an activating KIR-HLA genotype; KIR2DS2 (+) HLA-C group 1/2 homozygous. Inversely, non-response was associated with the relatively inhibitory KIR2DS2 (-) HLA-C group 1/2 heterozygous genotype. The KIR and HLA-C genotype of an RA patient may provide predictive information for response to anti-TNF-α therapy.
