Chlorogenic acid (ChA)-one of the most abundant polyphenol compounds in the human diet-exerts anti-inflammatory activities. The aim of this study was to investigate the effect of ChA on gut microbiota in ulcerative colitis (UC). Colitis was induced by 2.5% dextran sulfate sodium (DSS) in C57BL/6 mice, which were on a control diet or diet with ChA (1 mM). The histopathological changes and inflammation were evaluated. Fecal samples were analyzed by 16S rRNA gene sequencing. ChA attenuated several effects of DSS-induced colitis, including weight loss, increased disease activity index, and improved mucosal damage...

CD177 presents antigens in allo- and autoimmune diseases on the neutrophil surface. Individuals can be either CD177-deficient or harbor distinct CD177(neg) and CD177(pos) neutrophil subsets. We studied mechanisms controlling subset-restricted CD177 expression in bimodal individuals. CD177(pos), but not CD177(neg) neutrophils, produced CD177 protein and mRNA. Haplotype analysis indicated a unique monoallelic CD177 expression pattern, where the offspring stably transcribed either the maternal or paternal allele...

Non-small cell lung cancer (NSCLC) accounts for >85% of incidences of lung cancer, for which the predicted 5-year survival rates are low and recurrence rates remain high. Although it has been reported that the patients with SCLC cells that possess the cluster of differentiation (CD) 117 marker exhibited poor prognosis and poor response to chemotherapy, no studies concerning the association of CD117 expression with prognosis of the patients with NSCLC have been reported. An in vitro study reportedly revealed that CD117-positive cell populations in NSCLC cell lines exhibited cancer stem cell (CSC) phenotypes including self-renewal and chemoresistance...

BACKGROUND: Neutrophils are accumulated in inflamed mucosa of IBD and play an important role in the pathogenesis. CD177 is expressed in neutrophils specifically and upregulated during inflammation. However, the role of CD177(+) neutrophils in pathogenesis of IBD remains elusive. MATERIALS AND METHODS: Expression of CD177 was analysed in peripheral blood and intestinal mucosa from patients with IBD using quantitative RT-PCR, flow cytometry and immunohistochemistry...

Proteinase 3 is a serine protease found in neutrophil granules and on the extracellular neutrophil membrane (mPR3). mPR3 is a major antigen for anti-neutrophil cytoplasmic antibodies (PR3-ANCAs), autoantibodies causing fatal autoimmune diseases. In most individuals, a subpopulation of neutrophils also produce CD177, proposed to present additional PR3 on the surface, resulting in CD177(neg)/mPR3(low) and CD177(pos)/mPR3(high) neutrophil subsets. A positive correlation has been shown between mPR3 abundance, disease incidence, and clinical outcome...

BACKGROUND: Interleukin (IL)-25 (IL-17E) is a proinflammatory cytokine that plays an important role in the T-helper type 2 cell pathway. The effects of IL-25 are mediated by its specific receptor, IL-17RB. Previous studies have defined an IL-17RB(+) granulocyte population known as type 2 myeloid (T2M) cells that express T-helper type 2 cell cytokines. The correlation of IL-17RB(+) granulocytes, T2M cells, and asthma parameters is unknown. OBJECTIVE: To investigate the relation of IL-17RB(+) granulocytes (and its subset, T2M cells) in patients with asthma with clinical parameters including spirometric values and the Asthma Control Test (ACT)...

We describe a patient who presented with prolonged neutropenia due to anti-human neutrophil antigen (HNA)-2 (CD177) antibody after allogeneic bone marrow transplantation. A granulocyte immunofluorescence test showed bimodal expression of antineutrophil antibody that resulted from specific binding of anti-HNA-2 to CD177(+) neutrophils from healthy donors. The patient did not respond to granulocyte colony stimulating factor, which is able to upregulate CD177 expression on neutrophils. The low percentage of CD177(+) cells in the few remaining neutrophils supports the possibility of elimination of CD177-upregulated neutrophils...

BACKGROUND. Novel rapid diagnostics for active tuberculosis (TB) are required to overcome the time delays and inadequate sensitivity of current microbiological tests that are critically dependent on sampling the site of disease. Multiparametric blood transcriptomic signatures of TB have been described as potential diagnostic tests. We sought to identify the best transcript candidates as host biomarkers for active TB, extend the evaluation of their specificity by comparison with other infectious diseases, and to test their performance in both pulmonary and extrapulmonary TB...

Multiple Sclerosis (MS) is an inflammatory disease with neurodegenerative alterations, ultimately progressing to neurological handicap. Therapies are effective in counteracting inflammation but not neurodegeneration. Biomarkers predicting disease course or treatment response are lacking. We investigated whether altered gene and protein expression profiles were detectable in the peripheral blood of 78 relapsing remitting MS (RR-MS) patients treated by disease-modifying therapies. A discovery/validation study on RR-MS responsive to glatiramer acetate identified 8 differentially expressed genes: ITGA2B, ITGB3, CD177, IGJ, IL5RA, MMP8, P2RY12, and S100β...

OBJECTIVES: This review article describes the role of neutrophils in mucosal injury and the resulting crypt abscesses characteristic of ulcerative colitis. We also review selected biomarkers for monitoring neutrophil presence and activity in the mucosa as well as their potential as therapeutic targets. MATERIAL: We have collated and selectively reviewed data on the most prominent well-established and emerging neutrophil-related biomarkers and potential therapeutic targets (calprotectin, lactoferrin, CXCR1, CXCR2, MMP-9, NGAL, elafin, HNE, pANCAs, MPO, CD16, CD177, CD64, HNPs, SLPI and PTX3) in ulcerative colitis...

Sepsis represents the host's systemic inflammatory response to an infection. In this condition, immune response associates a marked inflammatory response and the delayed development of severe dysfunctions affecting both innate and adaptive responses. As neutrophils are the first line of defense against infection, they are central to the pathophysiology of sepsis in first hours. Nevertheless, their role during immunosuppression phase remains elusive. The main objective of the current work was to perform a transcriptomic study on purified neutrophils from septic shock patients (n=9) so as to identify genes that are differentially expressed during the first week after disease onset both (3-4 and 6-8days) versus healthy donors...

We performed gene expression microarray analysis coupled with spherical self-organizing map (sSOM) for artificially developed cancer stem cells (CSCs). The CSCs were developed from human induced pluripotent stem cells (hiPSCs) with the conditioned media of cancer cell lines, whereas the CSCs were induced from primary cell culture of human cancer tissues with defined factors (OCT3/4, SOX2, and KLF4). These cells commonly expressed human embryonic stem cell (hESC)/hiPSC-specific genes (POU5F1, SOX2, NANOG, LIN28, and SALL4) at a level equivalent to those of control hiPSC 201B7...

BACKGROUND: Human neutrophil antigen-2 is located on a glycosylphosphatidylinositol-anchored receptor, CD177. Humans not expressing CD177 on their neutrophils may, under defined conditions, form isoantibodies. The genetic background for the absence of CD177 is not fully understood, and genetic screening of patients and donors is currently unavailable. A recent study has documented two mutations associated with CD177 absence: a nonsense polymorphism c.843A>T and a single-base deletion c...

ANCA to either PR3 or MPO are found in patients with necrotizing vasculitis and glomerulonephritis. ANCA binding to their target antigens on neutrophils and subsequent neutrophil activation are pivotal disease mechanisms that lead to vascular inflammation and necrosis. ANCA interaction with PR3 is more complex than with MPO as the neutrophil-specific CD177 receptor is involved in PR3 surface expression and PR3-ANCA-induced neutrophil activation. Modeling human disease is important to clinical research. Highly successful mouse models of MPO-ANCA vasculitis exist; however, recapitulating PR3-ANCA vasculitis has not been successful...

We implemented a two-stage study to predict late occurring hematologic acute radiation syndrome (HARS) in a baboon model based on gene expression changes measured in peripheral blood within the first two days after irradiation. Eighteen baboons were irradiated to simulate different patterns of partial-body and total-body exposure, which corresponded to an equivalent dose of 2.5 or 5 Gy. According to changes in blood cell counts the surviving baboons (n = 17) exhibited mild (H1-2, n = 4) or more severe (H2-3, n = 13) HARS...

Most humans harbor both CD177neg and CD177pos neutrophils but 1-10% of people are CD177null, placing them at risk for formation of anti-neutrophil antibodies that can cause transfusion-related acute lung injury and neonatal alloimmune neutropenia. By deep sequencing the CD177 locus, we catalogued CD177 single nucleotide variants and identified a novel stop codon in CD177null individuals arising from a single base substitution in exon 7. This is not a mutation in CD177 itself, rather the CD177null phenotype arises when exon 7 of CD177 is supplied entirely by the CD177 pseudogene (CD177P1), which appears to have resulted from allelic gene conversion...

Generally, B-cell responses against human platelet antigens are assessed by the serological detection of specific platelet antibodies, mostly against β3 integrin. However, this approach seems to be of low sensitivity, since platelet autoantibodies against αIIbβ3 are detected in only 50% of all patients with immune thrombocytopenia (ITP). In this study, a novel B-cell ELIspot method was established to characterize the specificity of mouse monoclonal antibodies (moabs) against human β3 integrin. Moabs produced by hybridomas were immobilized on membrane and bound antibodies were visualized as spots using biotinylated recombinant proteins αIIbβ3 or αvβ3 and the enzyme labeled streptavidin-substrate system...

Emerging evidence shows that dietary agents and phytochemicals contribute to the prevention and treatment of ulcerative colitis (UC). We first reported the effects of dietary caffeic acid (CaA) on murine experimental colitis and on fecal microbiota. Colitis was induced in C57BL/6 mice by administration of 2.5% dextran sulfate sodium (DSS). Mice were fed a control diet or diet with CaA (1 mM). Our results showed that dietary CaA exerted anti-inflammatory effects in DSS colitis mice. Moreover, CaA could significantly suppress the secretion of IL-6, TNFα, and IFNγ and the colonic infiltration of CD3+ T cells, CD177+ neutrophils and F4/80+ macrophages via inhibition of the activation of NF-κB signaling pathway...
