Brief Summary

Connective tissue diseases (CTD) or systemic autoimmune diseases (SADs) as they are known today are a group of chronic inflammatory conditions with autoimmune aetiology with few treatment options and difficult diagnosis.Brest team contribute to performe a new classification of the following systemic autoimmune diseases in a European Union's Seventh Framework Programme. The aim of this research consiteis to reclassify the individuals affected by SADs into molecular clusters instead of clinical entities through the determination of molecular profiles using several "Omics" techniques.

Outcome Measures

Primary Outcomes (8)

  • Gene expression in total blood

    Gene expression will be done using commercial gene expression microarrays in total blood from all samples using the RNA Paxgene tube.

    2 years

  • Flow cytometry analysis to determine cell proportions in the total blood mixture in all individuals.

    9 optimized panels of antibodies will be used to determine cell subpopulations in peripheral blood (including very minor cell populations).

    24 hours

  • Genotyping

    Genotyping will be done using a whole genome array.

    2 years

  • Metabolite determination

    Metabolite determination in plasma and urine using Nuclear Magnetic Resonance

    2 years

  • Exosome isolation from plasma and urine

    set up of the methodology for isolating exosomes in these bodily fluids for gene expression analysis

    2 years

  • Cytokine profile determination

    88 different cytokines will be assessed with Luminex

    2 years

  • routine autoantibodies in serum

    set of serum autoantibodies will be determined in a European validated laboratory. Also, they will perform detection of antibodies against small lipid moieties i.e.antiphosphorylcholine),lupus anticoagulant and complement proteins in plasma.

    2 years

  • Gene methylation in total blood

    Methylation analysis will be done using the methylome 450k array using the DNA obtained from total blood. MicroRNA gene expression arrays using total blood.

    2 years
