Abstract: The present invention relates to field of treatment of rheumatoid arthritis. The inventors propose that PAD4, one of the enzymes which convert arginine into citrulline, is a target antigen for T cells that help the production of ACPA. They recently demonstrated that PAD immunization triggers anti-citrullinated fibrinogen antibody production in normal mice. Here, they demonstrate that the risk (OR) to develop RA associated with each of 12 HLA-DRB1 genotype correlates with the likelihood for the two HLA-DR molecules encoded by each genotype to bind at least one random peptide from PAD4, but not from citrullinated or native fibrinogen. PBLs from patients with RA, PsA and controls proliferate to PAD4 and they identify, notably, a peptide from PAD4, p8 (SEQ ID NO: 6), that stimulates T cells from RA patients and a few patients with PsA. Proliferative responses to p8 are associated with RA, shared epitope positive HLA-DR alleles and antibodies to PAD4.

Abstract: The present invention relates to peptides biomarkers that are specifically recognized by autoantibodies present in the sera of patients with Rheumatoid Arthritis (RA). More specifically, the invention provides epitopes of PAD4, of BRAF, and of calpastatin as well as methods and kits for using these sequences for the diagnosis of RA, in particular for the diagnosis of RA in CCP-negative subjects.

Abstract: The present invention relates to an in vitro method for diagnosing scleroderma in a subject, said method comprising the step of detecting in a biological sample obtained from the subject one or more autoantibodies recognizing one or more protein biomarkers selected from the group of proteins consisting of THEX1, AIF1, FGF2, EphB2, CLK1 and ANKS6.

Abstract: The present invention relates to biomarkers that are specifically recognized by autoantibodies present in a biological of patients with Rheumatoid Arthritis (RA). The invention provides methods and kits using these biomarkers for the diagnosis of RA, in particular for the diagnosis of early RA.

Abstract: The present invention relates to the identification and use of proteins with clinical relevance to rheumatoid arthritis (RA). In particular, the invention provides the identity of marker proteins that specifically react with RA-associated autoantibodies. Also provided are methods, arrays and kits for using these proteins in the diagnosis of RA, and in the selection and/or monitoring of treatment regimens.
