  • Publication number: 20230414732
    Abstract: Embedded Epitope Random Peptides (EERP) for the treatment of autoimmune diseases are provided. Each EERP is a polypeptide consisting of a random sequence of three or more amino acids in a specific molar ratio, within which is embedded an epitope composed of a specific amino acid sequence. Also provided is a method of treating an autoimmune disease or condition using the EERP.

  • Patent number: 9066905
    Abstract: The invention provides heteropolymer compositions and peptide compositions, and methods of making and using therapeutic compositions comprising amino acid heteropolymers for treatment of a subject for an autoimmune or an inflammatory disease, the heteropolymer compositions made by solid state synthesis. The invention also provides kits for assaying binding of a composition to a water-soluble MHC protein.

  • Patent number: 9028835
    Abstract: Random three- and four-amino acid copolymers having lengths of 14-, 35- and 50-amino acid residues are provided. The random copolymers have amino acids alanine, lysine and one or more of the hydrophobic amino acids valine, phenylalanine, tryptophan and tyrosine. Random three-amino acid copolymer FAK efficiently suppressed EAE induced in SJL/J (H-2S) mice with the encephalitogenic epitope PLP 139-151. Random four-amino acid copolymers VYAK and tryptophan-containing VWAK were efficacious in alleviating severity and duration of symptoms of EAE induced by MBP 85-99 (SEQ ID NO:2), in a humanized mouse model expressing genes for both an HLA-DR-2 linked to multiple sclerosis (MS) in humans and for a T cell receptor from an MS patient.

  • Publication number: 20150030560
    Abstract: The present invention is directed to polypeptides containing at least three amino acids randomly joined in a linear array; wherein at least one of the three amino acids is an aromatic amino acid, at least one of the three amino acids is a charged amino acid and at least one amino acid is an aliphatic amino acid. In a preferred embodiment the polypeptide contains three or four of the following amino acids: tyrosine, alanine, glutamic acid or lysine. According to the present invention, the present polypeptides bind to antigen presenting cells, purified human lymphocyte antigens (HLA) and/or Copolymer 1-specific T cells. Moreover, according to the present invention, these polypeptides can be formulated into pharmaceutical compositions for treating autoimmune disease. The present invention further contemplates methods of treating an autoimmune disease in a mammal by administering a pharmaceutically effective amount of any one of the present polypeptides to the mammal.

  • Publication number: 20110286959
    Abstract: Random three- and four-amino acid copolymers having lengths of 14-, 35- and 50-amino acid residues are provided. Fifty-mers of FEAK were effective inhibitors of MBP 85-99- or proteolipid protein (PLP) 40-60-specific HLA-DR-2-restricted T cell clones. These copolymers efficiently suppressed the mouse disease EAE, which was induced in a susceptible SJL/J (H-2s) strain of mice with either whole spinal cord homogenate (WSCH) or with the encephalitogenic epitope PLP 139-151 (SEQ ID NO:4). YFAK 50-mer having a molar ratio of about Y 0.8:F 0.2 inhibited binding of biotinylated MBP 85-99 epitope to HLA-DR-2 molecules more efficiently than either unlabeled MBP 85-99 or Copaxone®. YFAK and FAK copolymers efficiently suppressed EAE induced in SJL/J (H-2S) mice with the encephalitogenic epitope PLP 139-151.
