Title:
IDENTIFICATION OF HLA-DR4 EPITOPE AND USE FOR TREATMENT OF ARTHRITIS
Document Type and Number:
WIPO Patent Application WO/2011/071039
Kind Code:
A1
Abstract:
Provided are novel means for determining the amino acid sequence structure of a specific antigen polypeptide (epitope) presented by RA-sensitive MHC class II molecules, such as HLA-DR4 or HLA-DR1, with respect to CD4-positive T cells, and for preventing or treating disease associated with HLA-DR4 or HLA-DR1, including rheumatoid arthritis, using this type of epitope. It is clarified that a polypeptide which is formed from a total of 12 to 20 amino acid residues and includes a specific amino acid sequence motif comprising the amino acid sequence X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 (Seq. ID No. 1) is an epitope presented by HLA-DR4 or HLA-DR1.
