Histo-blood group antigens (HBGA) expressed on enterocytes are proposed receptors for rotaviruses and can be measured in saliva. Among 181 Pakistani infants in a G1P[8] rotavirus vaccine trial that were seronegative at baseline, anti-rotavirus IgA seroconversion rates after 3 vaccine doses differed significantly by HBGA phenotype: lowest (19%) among infants who were non-secretors (ie, do not express the carbohydrate synthesized by FUT2 gene), intermediate among non-blood group O secretors (30%) and highest (51%) among O-blood group secretors...

Deregulated expression of c-myc and bcl-xL is long known to generate transformed B cells in humans and mice. We overexpressed these genes to induce in vitro and in vivo differentiation of fetal liver-derived mouse pre-BI cells to B1-lineage pre-BII-like, immature and mature B-cell lines and to Ig-secreting cells. In vitro, doxycycline-controlled c-myc/bcl-xL-overexpressing CD19(+) CD93(+) c-kikt(+) IgM(-) pre-BI cells differentiate to and survive as CD19(+) CD93(+) c-kit(-) IgM(+) immature B1 cells. Timed CpG-stimulation of these oncogene-overexpressing pre-B or immature B1 cells generates either CD19(+) CD93(low) c-kit(-) IgM(-) SLC(-) pre-BII-like, or IgM(+) MHCII(+) CD73(+) CD80(+) CD40(+) mature B1-cell lines and IgM-secreting B1 cells in vitro and fixes their state of differentiation...

The prognostic effect of hypogammaglobulinemia (HGG), clinical and biologic characteristics on the infection risk and outcome has been retrospectively analyzed in 899 patients with stage A chronic lymphocytic leukemia (CLL). Low levels of IgG were recorded in 19.9% of patients at presentation, low levels of IgM and/or IgA in 10.4% and an additional 20% of patients developed HGG during the course of the disease. Before the start of any treatment, 160 (12.9%) patients experienced at least one grade ≥3 infection requiring a systemic anti-infective treatment and/or hospitalization...

We describe here the case of a boy who presented with pulmonary infections, feeding difficulties due to velopharyngeal insufficiency and gastroesophageal reflux, myopathy, and hypotonia soon after birth. Later, he was also found to have an elevated immunoglobulin (Ig) E and mild eczema and was diagnosed with inflammatory bowel disease. Further immunological screening at the age of 7 years showed low B and NK cell numbers but normal CD4(+) and CD8(+) T cells and notably, normal numbers of CD4(+) regulatory T (Treg) cells...

In spite of the interest for chronic renal diseases (CKD) in pregnancy data on specific diseases is fragmentary; while recent studies analysed the most common glomerulonephritides (GN), none was addressed at GN as a group. The aim of our study was to analyse the main pregnancy-related outcomes in GN patients in a large multicentre cohort. Patients with a diagnosis of GN were selected from the TOCOS cohort (TOCOS: TOrino Cagliari Observational Study): out of 714 singleton deliveries GN was the diagnosis in 126; lupus GN and IgA nephropathy accounted for 37 and 33 cases; 1418 low-risk singleton deliveries followed-up in the same Centers served as controls (non diabetic, non nephropathic, non obese women, without any other known chronic illness; pregnancies after ovodonation or in vitro fertilisation were excluded, if declared)...

Background -Antiphospholipid syndrome (APS) is characterized by recurrent thrombosis and/or gestational morbidity in patients with antiphospholipid autoantibodies (aPL). Predictive value of the presence of aPL is low and new markers are necessary to identify aPL carriers at higher risk and take preventive measures on them.The presence of circulating immune complexes of IgA bound to Beta2-glycoprotein-I (B2A-CIC) has been associated with occurrence of acute thrombotic events (TEV). In this work we study its possible predictive value for appearance of TEV in patients who are going to undergo transplant surgery, a well-known trigger of TEV in aPL carriers 94...

A pasteurization temperature monitoring system has been designed using FoneAstra, a cellphone-based networked sensing system, to monitor simulated flash-heat (FH) pasteurization. This study compared the effect of the FoneAstra FH (F-FH) method with the Sterifeed Holder method currently used by human milk banks on human milk immune components (immunoglobulin A (IgA), lactoferrin activity, lysozyme activity, interleukin (IL)-8 and IL-10). Donor milk samples (N = 50) were obtained from a human milk bank, and pasteurized...

Clinical and laboratory identification of the underlying risk of respiratory illness in athletes has proved problematic. The aim of this study was to determine whether clinical data, combined with immune responses to standardised exercise protocols and genetic cytokine polymorphism status, could identify the risk of respiratory illness (symptoms) in a cohort of highly-trained athletes. Male endurance athletes (n=16; VO2max 66.5 ± 5.1 mL.kg-1.min-1) underwent a clinical evaluation of known risk factors by a physician and comprehensive laboratory analysis of immune responses both at rest and after two cycling ergometer tests: 60 min at 65% VO2max (LONG); and 6 x 3 min intervals at 90% VO2max (INTENSE)...

BACKGROUND: Expression quantitative trait loci (eQTL) databases represent a valuable resource to link disease-associated SNPs to specific candidate genes whose gene expression is significantly modulated by the SNP under investigation. We previously identified signal inhibitory receptor on leukocytes-1 (SIRL-1) as a powerful regulator of human innate immune cell function. While it is constitutively high expressed on neutrophils, on monocytes the SIRL-1 surface expression varies strongly between individuals...

We compared the HIV-1-specific immune responses generated by targeting HIV-1 envelope protein (Env gp140) to either CD40 or LOX-1, two endocytic receptors on dendritic cells (DCs), in Rhesus macaques primed with a poxvirus vector (NYVAC-KC) expressing Env gp140. The DC-targeting vaccines, humanized recombinant monoclonal antibodies fused to Env gp140, were administered as a boost with poly ICLC adjuvant either alone or co-administered with the NYVAC-KC vector. All the DC-targeting vaccine administrations with poly ICLC increased the low-level serum anti-Env IgG responses elicited by NYVAC-KC priming significantly more (up to P =0...

BACKGROUND: IgA nephropathy is the most common progressive glomerular disease to end stage renal failure worldwide. Calcineurin inhibitors (CNIs) is a selective immunosuppressant widely used in organ transplantation. The efficacy and safety of calcineurin inhibitors for the treatment of IgA nephropathy remain uncertain. METHODS: We performed a systematic literature search using the PubMed, Embase, Science Citation Index, Ovid evidence-based medicine, Chinese Biomedical Literature (CBM) and Chinese science and technology periodicals (CNKI, VIP, and Wan Fang) for randomized, controlled trials of CNIs therapy of IgA nephropathy...

The non-replicating attenuated poxvirus vector NYVAC expressing clade C(CN54) HIV-1 Env(gp120), Gag-Pol-Nef antigens (NYVAC-C) showed in phase I clinical trials limited immunogenicity. To enhance the capacity of the NYVAC vector to trigger broad humoral responses and a more balanced activation of CD4(+) and CD8(+) T cells, here we compared the HIV-1-specific immunogenicity elicited in non-human primates immunized with two replicating NYVAC vectors that have been modified by the insertion of K1L and C7L vaccinia viral host-range genes and express clade C(ZM96) trimeric HIV-1 gp140 protein or a Gag(ZM96)-Pol-Nef(CN54) polyprotein as Gag-derived virus-like particles (termed NYVAC-C-KC)...

BACKGROUND/OBJECTIVES: Polymeric immunoglobulin receptor (pIgR) traffics Immunoglobulins (IgA and IgM) through epithelial cells in normal mucosae but neither are expressed in the normal pancreas. Recent work from our laboratory suggested pIgR may be upregulated in pancreatic ductal adenocarcinoma (PDAC). Our aim was to assess the role of pIgR in human PDAC. METHODS: pIgR expression was manipulated (siRNA and shRNA) in cell lines to evaluate its subsequent effect on cell behaviour in 2D assays as well as 3D organotypics models...

Besides association with acute rheumatic fever (ARF) and acute glomerulonephritis (APSGN), in up to 40% of cases, Group A β-haemolytic streptococcal (GABHS) infections are also implicated as a trigger for Henoch-Schonlein purpura (HSP). A 7-year-old girl with GABHS throat infection who developed HSP, APSGN and rheumatic carditis is reported. She presented with palpable purpura and arthritis in both ankles and later developed carditis characterised by mitral/aortic regurgitation and glomerulonephritis characterised by mixed nephritic/nephrotic syndrome...

BACKGROUND: Serologic testing for celiac disease includes tissue transglutaminase and endomysial antibodies. In addition to these tools, assays for deamidated gliadin peptide antibodies have been shown to have sensitivity and specificity that are comparable to tissue transglutaminase testing, and are increasingly being used for celiac disease testing. AIMS: The goal of this study is to evaluate the utility of deamidated gliadin peptide (DGP) testing in the setting of a negative tissue transglutaminase (TTG) IgA test...

Despite the presence of endocrine disrupting mercury, PAHs, alkylphenols and bisphenol A in inhaled air, scientific literature lacks information on their penetration into the lungs. Large lung capacity in birds makes this route of penetration more significant than in other animals. The studies were conducted on lungs of herring gulls found in the Gulf of Gdansk area. The results were juxtaposed with other tissues, including the intestines, which reflect the main, alimentary penetration route of harmful substances into the organism...

Treatment options for chronic hepatitis B (CHB) infection are extremely limited. CXCR5(+) CD8(+) T cell is a novel cell subtype and could possess strong cytotoxic properties in HIV infection. In this study, we investigated the role of CXCR5(+) CD8(+) T cells in CHB patients. Compared to healthy individuals, both CHB patients and hepatitis B virus (HBV)-infected hepatocellular carcinoma patients presented significant upregulation of CXCR5(+) CD8(+) T cells in peripheral blood, in which CXCR5(+) CD8(+) T cells were negatively correlated with the frequency of CXCR5(+) CD4(+) T cells in CHB patients...
