Comparative analyses of human saliva and plasma IgG antibody reactivities [HBV]

ABSTRACT: Saliva based diagnostics is a rapidly evolving field due to the large potential of saliva and the simple sample collection. A systematic comparison of IgG antibody profiles in saliva and plasma is currently lacking in scientific literature. Our hypothesis is that IgG profiles are equal in blood and saliva. By showing the equality of the profiles and relative IgG antigenic reactivities towards proteins and peptides we provide evidence that plasma IgG reactivities can be inferred from saliva IgG reactivities. IgG antibodies were isolated from human saliva and plasma samples. The reactivities of IgG isolates were analysed on peptide microarrays displaying linear epitopes of EBV (EBNA1 protein) and HBV (Large envelope protein) virus. Peptide arrays were printed by JPT Peptide Technologies (Berlin, Germany). We show high similarity of saliva and plasma IgG profiles on these two platforms and argue for generalisation from this subset to the whole immunological IgG antibody profile.

The Diagnostic Value of Salivary microRNA in Esophageal Cancer

Project description:Tissue microRNAs (miRNAs) can detect cancers and predict prognosis. Several recent studies reported that tissue, plasma, and saliva miRNAs share similar expression profiles. In this study, we investigated the diagnostic value of salivary miRNAs (including whole saliva and saliva supernatant) for detection of esophageal cancer. By Agilent microarray, six deregulated miRNAs from whole saliva samples from seven patients with esophageal cancer and three healthy controls were selected. The six selected miRNAs were subjected to validation of their expression levels by RT-qPCR using both whole saliva and saliva supernatant samples from an independent set of 39 patients with esophageal cancer and 19 healthy controls.

Phase II randomised clinical trial of personalized peptide vaccination in combination with Dai-kenchu-to for colorectal cancer patients resistant to standard therapies.

Project description:Interventions: arm1: The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund’s adjuvant every week (3.0 mg/each peptide; 6 times/cycle). Dai-kenchu-to(5 g/time, 3 times/day) will be orally administered from the date of the first vaccination to the date of the sixth vaccination. If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks). arm2: The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund’s adjuvant every week (3.0 mg/each peptide; 6 times/cycle). If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks). Primary outcome(s): Comparison of immune-enhancing effects (changes in anti-peptide IgG titers in plasma)between two groups. Study Design: Parallel Randomized

Allelic Differences Account for Gene Expression Differences Among Population.

Project description:Expression level of genes in lymphoblasts from individuals in three HapMap populations (CEU, CHB, JPT) were compared. More than 1,000 genes were found to be significantly different (Pc<0.05) in mean expression level between the CEU and CHB+JPT samples. Keywords: Comparison of Gene Expression Profiles from Lymphoblastoid cells

Exosomal miRNA profiling of plasma- and saliva-derived exosomes

Project description:Exosomes were isolated from plasma and saliva of healthy individuals and head and neck cancer (HNSCC) patients. miRNA profiling of plasma- and saliva-derived exosomes was performed using nCounter SPRINT system. Diagnostic panels were selected from the exosomal miRNA profile.

IgM from common variable immunodeficiency patients narrowly recognizes erythrocyte and platelet glycans

Project description:Autoantibody-mediated cytopenias (AICs) regularly occur in profoundly IgG-deficient common variable immunodeficiency (CVID) patients. The isotypes, antigenic targets, and origin(s) of disease-causing autoantibodies in this patient population are unclear. Herein, we report that erythrocytes and platelets from CVID patients with AICs (CVID+AIC) are coated with autoreactive IgM. Glycan array-based analyses of CVID+AIC plasma IgM revealed narrow reactivities to erythrocytic I/i antigens and platelet expressed I/i antigen-related glycans but starkly lower binding to hundreds of other pathogen and tumor-associated carbohydrates. Polyclonal B-cell receptors with corresponding I/i antigen reactivities were highly enriched among CVID+AIC circulating marginal zone (MZ) B cells. Within secondary lymphoid tissues, MZ B cells secreted copious IgM when activated by IL-10 secreting FOXP3-CD25hiTfh cells. In lymph nodes from immunocompetent controls, MZ B cells localized outside of GCs near rare FOXP3-CD25+ cells and plentiful FOXP3+ regulatory T cells. In CVID+AIC lymph nodes, counterpart cells localized to similar anatomic positions but CD25hiTfh cells greatly outnumbered regulatory T cells. In total, our findings indicate glycan-reactive IgM autoantibodies produced outside of GC borders may contribute to the autoimmune pathogenesis of CVID.
