Autoantibodies are abundant in all human sera: a demographic characterization via protein microarrays

ABSTRACT: Human serum samples were probed onto human protein microarrays in order to ascertain the number and diversity of naturally ocurring self-reactive IgG autoantibodies. In the study presented here, 166 human serum samples were probed onto human protein microarrays in order to identify self-reactive IgG autoantibodies and study their number and diversity in variable donor demographics. Microarray data were analyzed using several statistical programs, including Prospector v5.2, and autoantibodies with a relative fluorescence Z-factor value of greater than or equal to 0.4 were considered significant.

The presence of self-reactive IgG autoantibodies in human sera is largely thought to represent a breakdown in central tolerance and is typically regarded as a harbinger of autoimmune pathology. In the present study, immune-response profiling of human serum from 166 individuals via human protein microarrays demonstrates that IgG autoantibodies are abundant in all human serum, usually numbering in the thousands. These IgG autoantibodies bind to human antigens from organs and tissues all over the b ...[more]

Diagnosis of Parkinson's Disease Based on Disease-Specific Autoantibody Profiles

Project description:Parkinson's Disease (PD) and Non-Demented Control (NDC) human sera were probed onto human protein microarrays in order to identify differentially expressed autoantibody biomarkers that could be used as diagnostic indicators. In the study presented here, 29 PD and 40 NDC human serum samples were probed onto human protein microarrays in order to identify differentially expressed autoantibodies. Microarray data was analyzed using several statistical significance algorithms, and autoantibodies that demonstrated significant group prevelance were selected as biomarkers of disease. Prediction classification analysis tested the diagnostic efficacy of the identified biomarkers; and differentiation of PD samples from other neurodegeneratively-diseased and non-neurodegeneratively-diseased controls (Alzheimer's disease, multiple sclerosis, and breast cancer) confirmed their specificity.

Broad spectrum antibodies to self-antigens and cytokines in RAG deficiency

Project description:Overall, this work describes the largest cohort of patients with RAG mutations and an associated phenotype consisting of combined immunodeficiency and granulomatous lesions and/or autoimmunity (CID-G/AI). By using multiple methods (microarray, ELISA and multiplex bead technology), we have consistently identified a distinctive signature of anti-cytokine antibodies in patients with RAG-dependent immunodeficiencies, especially in those with CID-G/AI and a history of severe viral infections. These autoantibodies were not detected in a large panel of patients with other forms of primary immunodeficiency, and may therefore represent a novel biomarker panel of this condition. Known autoantigens, cytokines, chemokines, growth factors and receptors were printed onto microarrays. All targets were printed in triplicate. Arrays were probed with diluted plasma and autoantibodies were detected with a AF647 conjugated anti-human IgG secondary.

Protein microarray (Protoarray, Invitrogen) screening with APECED patient, healthy relative and healthy control serum samples

Project description:APECED is a monogenic autoimmune disease caused by defects in Autoimmune Regulator (AIRE) gene that promotes the expression of self-antigens in the thymus. The autoimmune phenotype in APECED is variable, and multiple proteins are targeted by autoantibodies. This study used human protein arrays to screen autoantibody targets in APECED and to identify novel autoimmune targets. Altogether 100 sera samples from 82 individual APECED patients were profiled using Protoarray antibody specificity service at Invitrogen as well as samples from 12 healthy controls and 8 healthy relatives. The protein arrays (ProtoArray v5.1) were probed as described in Invitrogenâs protocol for Immune Response BioMarker Profiling using detection reagent (Alexa Fluor 647 Goat Anti-Human IgG A21445, Invitrogen) and blocking buffer (Blocking Buffer Kit PA055, Invitrogen). Arrays were scanned using a GenePix 4000B fluorescent scanner, and the data was acquired with GenePixÂ® Pro software. The arrays were probed with sera at a dilution of 1:500.

Human cerebrospinal fluid autoantibody lipid microarray profiling (Fig. 2A)

Project description:Lipids comprise 70% of the myelin sheath, and autoantibodies against lipids may contribute to the demyelination that characterizes multiple sclerosis (MS). We used lipid antigen microarrays and lipid mass spectrometry to identify bona fide lipid targets of the autoimmune response in MS brain and an animal model of MS to explore the role of the identified lipids in autoimmune demyelination. We found that autoantibodies in MS target a phosphate group in phosphatidylserine and oxidized phosphatidylcholine derivatives. Administration of these lipids ameliorated experimental autoimmune encephalomyelitis by suppressing activation and inducing apoptosis of autoreactive T cells, effects mediated by the lipids' saturated fatty-acid side chains. Thus, phospholipids represent a natural anti-inflammatory class of compounds that have potential as novel therapeutics for MS. Fig. 2A. Mini-Array I: IgG antibody reactivity to various glycero-3-phosphocholine lipids in CSF samples from patients with relapsing remitting MS and from control patients with other neurological disease. Lipid hits with the lowest FDR (q=0.029) were clustered according to their reactivity profiles. 47 different lipids were custom-spotted in duplicate using the CAMAG Automatic TLC Sampler (ATS4) robot to spray 200 nl of 10 to 100 pmol of lipids onto PVDF membranes affixed to the surface of microscope slides. The slides were probed with cerebrospinal fluid (CSF) from 24 human patient samples. 25 slides total: 13 relapsing-remitting MS, 11 other neurological disease, and 1 secondary Ab alone (not included in this submission). CSF diluted 1/20. HRP-conjugated secondary Ab (goat anti-human IgM/IgG) diluted 1/175. ECL for 3 minutes.

Nucleic Acid Programmable Protein Arrays (NAPPA) Somatic p53 Mutations

Project description:Purpose: Mutations in TP53 induce autoantibody immune responses in a subset of cancer patients, which have been proposed as biomarkers for early detection. Here, we investigate the association of p53 specific autoantibodies with multiple tumor subtypes and determine the association with p53 mutation status and epitope specificity. Experimental Design: IgG p53 autoantibodies (p53-AAb), were quantified in 412 serum saples using a programmable ELISA assay from patients with serous ovarian, pancreatic adenocarcinoma, and breast cancer. To determine if patients generated mutation specific autoantibodies we designed a panel of the most relevant 51 p53 point mutant proteins, to be displayed on custom programmable protein microarrays. To determine the epitope specificity we displayed 12 overlapping tiling fragments and 38 N- and C-terminal deletions spanning the length of the wild-type p53 proteins. Results: We detected p53-AAb with sensitivities of 58.8% (ovarian), 22% (pancreatic), 32% (triple negative breast cancer), and 10.2% (HER2+ breast cancer) at 94% specificity. Sera with p53-AAb contained broadly-reactive autoantibodies to 51 displayed p53 mutant proteins, demonstrating a polyclonal response to common epitopes. All p53-AAb displayed broad polyclonal immune response to both continuous and discontinuous epitopes at the N- and C-terminus as well as the DNA binding domain. Conclusion and clinical relevance: In this comprehensive analysis, mutations in tumor p53 induce strong, polyclonal autoantibodies with broadly reactive epitope specificity. The immunoreactivity was compared between 60 pancreactic ductal adenocarcinoma cases and 63 benign pancreatic disease controls against 52 unique mutant p53 and 379 human proteins that were printed on microscope slides.
