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

ABSTRACT: 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.

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

Project description: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 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 IgG and IgM reactivity in B6 and BXD2 mice with spontaneous systemic autoimmune disease

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.
