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 94 years-old) were included...

The chronic chikungunya arthritis symptoms closely mimic the rheumatoid arthritis (RA) symptoms, thus making it difficult to distinguish between these two clinical entities. The current comparative study characterizes NK (CD3(-)CD56(+)) and NK-like T (CD3(+)CD56(+)) cell responses in patients with chronic chikungunya arthritis and RA. Phenotype and functions of NK and NK-like T cells repertoire were assessed in 56 chronic chikungunya arthritis, 26 RA patients and 82 controls using flow cytometry. TNF-α and IFN-γ-secreting NK-like T cells were high in both chronic arthritis patients than in controls...

Although tonsillectomy are used as therapeutic options to prevent chronic renal failure in IgA nephropathy (IgAN) patients, the relationship between IgAN and tonsils is not fully proved by basic research. Recently, circulating CX3CR1-positive cells were reportedly involved in promoting hematuria in patients with IgAN. In this study, we focused on the expression of CX3CR1 in tonsillar mononuclear cells in IgAN patients. Immunohistological analysis revealed greater distribution of CX3CR1-positive cells in the inter-follicular area of tonsils in IgAN patients than in non-IgAN patients...

BACKGROUND: Complement-binding assays are proposed to better stratify the risk of antibody-mediated rejection associated-graft failure. Despite promising clinical results, some have suggested that the MFI of anti-HL antibodies may influence these tests. METHODS: We investigated the impact of Abs MFI reduction, induced by plasmapheresis, on C1q- and C3d-binding assays. Sera provided from 7 sensitized kidney transplant patients were analysed. RESULTS: Four hundreds and thirty-three SABs were analyzed...

Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer among Caucasians in the United States, with rising incidence over the past decade. Treatment for non-melanoma skin cancer, including cSCC, in the United States was estimated to cost $4.8 billion in 2014. Thus, an understanding of cSCC pathogenesis could have important public health implications. Immune function impacts cSCC risk, given that cSCC incidence rates are substantially higher in patients with compromised immune systems. We report a systematic review of published associations between cSCC risk and the human leukocyte antigen (HLA) system...

Although exposure to potentially pathogenic nontuberculous mycobacteria (NTM) via soil and domestic water supplies is common, pulmonary infection and disease are confined to a small proportion of older individuals. Previously, alleles of a polymorphism in IL10 (rs1800896) were associated with NTM disease and we demonstrated elevated production of IL-10 by blood leukocytes from patients with pulmonary NTM. Here seven additional polymorphisms in IL10 were investigated in a larger cohort of Caucasian controls and patients with pulmonary NTM disease...

Many studies have investigated the relationship between KIR, HLA and acute myeloid leukemia (AML), but the results were different in different laboratories, and the data in Chinese population were limited. In this study, the distribution of KIR gene, KIR genotypes, HLA-C groups, HLA-Bw4, and KIR-HLA interaction from 273 healthy participants and 253 AML patients (M0-M6) in southern Chinese Han were determined to investigate the relationships among KIR, HLA and AML. The results showed that the frequencies of 2DS4del in M5 patients were significantly higher than those of the controls (65...

This study aimed to establish the occurrence and frequency of HLA alleles and haplotypes for a healthy British Caucasian population bioresource from Oxfordshire. We present the results of imputation from HLA SNP genotyping data using SNP2HLA for 5553 individuals from Oxford Biobank, defining one- and two-field alleles together with amino acid polymorphisms. We show that this achieves a high level of accuracy with validation using sequence-specific primer amplification PCR. We define six- and eight-locus HLA haplotypes for this population by Bayesian methods implemented using PHASE...

Human cytomegalovirus (HCMV) infection in children and young adults has been associated with changes in the innate immune system. We herein analyzed the possible effect of very long term HCMV infection on the expression of several NK cell receptors. Ninety HCMV-seropositive individuals were included and classified as young adults (n=30), elderly (n=30) and very elderly subjects (n=30). A peripheral blood sample was obtained and the expression of NK cell receptors (NKG2A, NKG2C, ILT2, CD161, KIR2DL1, KIR3DL1, and KIR3DL2) by NK and other lymphocyte subsets was assessed by flow cytometry...

Colorectal cancer (CRC) can occur anywhere in the colon or rectum and represents the third most common cancer in the world in both sexes. Natural killer cells (NK) are part of the innate immune system recognizing class I HLA molecules on target cells through their membrane receptors, called killer cell immunoglobulin-like receptors (KIR). The aim of our study was to evaluate the association between the KIR genes and HLA ligands in patients with colorectal cancer and healthy controls. We examined the polymorphism of 16 KIR genes and their HLA ligands in 154 caucasoid CRC patients and 216 controls...

The use of the calculated panel reactive antibody (CPRA) value and the implementation of allocation points for sensitized candidates by the United Network for Organ Sharing (UNOS) have improved access to kidney transplantation for highly sensitized candidates (98% CPRA and above). Despite this, a large population of highly sensitized candidates remain awaiting transplantation. To better define this population, we propose the use of two refinements of the standard UNOS CPRA, the CPRA with decimals or CPRAd, and the likelihood of a compatible donor (LCD)...

Ulcerative colitis (UC) is a chronic inflammatory disorder of unknown etiology and a polygenic disease. IL-27 encodes p28, a subunit of IL-12 family cytokines, and has been implicated in the pathogenesis of UC. The aims of the present study were to evaluate the genetic association of a variant of the IL-27 gene with UC and to further characterize the functional variant in the IL-27 gene that influences the risk for UC. Our data demonstrated that the genetic variant rs153109 in the 5' upstream region of IL-27 is significantly associated with UC in Chinese Han individuals...

The genetic background of human populations can influence the susceptibility and outcome of infection diseases. Toll-like receptors (TLRs) have been previously associated with susceptibility to human immunodeficiency virus (HIV) infection, disease progression and hepatitis C, virus (HCV) co-infection in different populations, although mostly in Europeans. In this study, we investigated the genetic role of endosomal TLRs on susceptibility to HIV infection and HCV co-infection through the analysis of TLR7 rs179008, TLR8 rs3764880, TLR9 rs5743836 and TLR9 rs352140 polymorphisms in 789 Brazilian individuals (374 HIV+ and 415 HIV-), taking into account their ethnic background...

BACKGROUND AND AIMS: HLA-G has well-recognized immunomodulatory properties, and this molecule is frequently expressed in the livers of hepatitis B virus (HBV)-infected patients. Because the HLA-G 14 bp-insertion/deletion polymorphism (rs371194629) has been associated with the magnitude of HLA-G expression, we evaluated this polymorphism in the recognized evolutionary forms of chronic HBV infection. METHODS: We studied 196 chronic HBV-infected patients (118 HBeAg-negative chronic hepatitis, 53 HBeAg-positive chronic hepatitis and 25 inactive carriers exhibiting low levels of serum HBVDNA and persistently normal ALT levels), and 202 healthy individuals...

Naïve CD4(+) T cells are pleiotropically divided into various T helper (Th) cell subsets, according to their pivotal roles in the regulation of immune responses. The differentiation of Th9 cells, an interleukin (IL)-9 producing subset, can be impacted by specific environmental cues, co-stimulation with transforming growth factor β (TGF-β) and IL-4, and other regulatory factors. Although IL-9 has been recognized as a classical Th2-related cytokine, recent studies have indicated that IL-9-producing cells contribute to a group of autoimmune disorders including systemic lupus erythematosus (SLE), multiple sclerosis (MS), inflammatory bowel diseases (IBD), rheumatoid arthritis (RA) and psoriasis...
