Autoimmune antigen and serum factor antigen reactivity in a cohort of patients with systemic lupus erythematosus (SLE) and healthy controls from the ABCoN cohort.

ABSTRACT: The aim of the study was to test the hypothesis that SLE patient sera contains IgG reactivity to serum factor antigens concomitant with prototypical autoimmne antigens. We diluted patient sera 1:250 and incubated dilutions on a nitrocellulose-platform array printed with whole protein antigens. In this study, serum from 45 individuals (subsetted into high and low interferon signature as well as healthy control categories) was profiled for IgG autoantibody reactivity to whole protein autoimmune and serum factor antigens. SLE and specifically IFN high patient sera was found using the significance analysis of microarrays (SAM) algorithm to be significantly more reactive with prototypical autoimmune antigens and select serum factor array antigens.

Autoimmune antigen and serum factor antigen reactivity in a cohort of patients with autoimmune polyendocrinopathy syndrome type 1(APS-1) and healthy controls.

Project description:The aim of the study was to test the hypothesis that APS-1 patient sera contains IgG reactivity to serum factor antigens concomitant with prototypical autoimmne antigens. We diluted patient sera 1:250 and incubated dilutions on a nitrocellulose-platform array printed with whole protein antigens. In this study, serum from 14 ndividuals (subsetted into APS-1 patient and healthy control categories) was profiled for IgG autoantibody reactivity to whole protein autoimmune and serum factor antigens. APS-1 patient sera was found using the significance analysis of microarrays (SAM) algorithm to be significantly more reactive with prototypical cytokine antigens previously identified as targets of autoantibodies.

Histone protein and peptide reactivity within patients with systemic lupus erythematosus (SLE) from the ABCoN cohort

Project description:The aim of the study was to test the hypothesis that IFN high SLE patient sera is more reactive to whole histone proteins and post-translationally modified histone peptides than IFN low patient sera. We diluted patient sera 1:250 and incubated dilutions on a nitrocellulose-platform array printed with whole protein and peptide histone antigens. In this study, serum from 30 patients subsetted into high and low interferon signature categories were profiled for IgG autoantibody reactivity to whole histone proteins, unmodified and post-translationally modified histone peptides. IFN high patient sera was found using the significance analysis of microarrays (SAM) algorithm to be significantly more reactive with whole histone and modified histone peptide antigens.

Autoimmune antigen and serum factor antigen reactivity in a cohort of patients with mycobacterium infection shown previously to be positive and negative for IgG autoantibodies to IFN-gamma.

Project description:The aim of the study was to test wether our microarray platform is capable of detecting previously described IgG autoantibodies to IFN-gamma. We diluted patient sera 1:250 and incubated dilutions on a nitrocellulose-platform array printed with whole protein antigens. In this study, serum from 10 individuals (subsetted into two groups: individuals positive or negative for previously described IFN-gamma-targeted autoantibodies) was profiled for IgG autoantibody reactivity to whole protein autoimmune and serum factor antigens. We found that IFN-gamma-targeted IgG autoantibodies were recognized in the IFNg-pos samples and also identified other array targets significantly associated with anti-IFNg positive individials using the significance analysis of microarrays (SAM) algorithm.

Autoimmune peptide antigen reactivity in normal B6 mice Pepperchip 2.0

Project description:The aim of the array was to determine the B6 mouse sera IgG and IgM reactivity profile to linear peptide epitopes. Pooled sera from three 6-9 month old B6 mice was diluted at 1:200 for IgG specific analysis or 1:1000 for IgM specific analysis and incubated on a PEPperPRINT peptide microarray platform printed with peptide autoantigens Pooled sera from three 6-9 month old B6 mice was profiled for IgG or IgM-specific analysis of autoantibody reactivity to peptide auto-epitopes printed in duplicate on a PepperPrint Chip.

Autoimmune peptide antigen IgG and IgM reactivity in B6 and BXD2 mice with spontaneous systemic autoimmune disease

Project description:The aim of the study was to determine B6 and BXD2 mouse sera IgG and IgM reactivity to linear peptide epitopes at different ages. Serum from B6 or BXD2 mice was diluted at 1:200 for IgG-specific analysis or 1:1000 for IgM specific analysis and incubated on a PEPperPRINT peptide microarray platform printed with peptide autoantigens. 80 pre-selected peptides based on a previous screen of pooled mouse serum BXD2 against the PEPperCHIPÂ® Autoimmunity Microarray with 2,733 linear B-cell epitopes were printed in duplicate in 16 copies on a custom PEPperCHIPÂ® Peptide Microarray. Flag (DYKDDDDKGG) and HA (YPYDVPDYAG) control peptides (10 spots each control) were randomly distributed in each array copy as controls. Sera from 2, 5, or 9 month old B6 or BXD2 mice was profiled for anti-mouse IgG or IgM-specific analysis of autoantibody reactivity to the peptide auto-epitopes.
