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. 1. A terpolymer consisting essentially of tyrosine , alanine and lysine randomly polymerized into a polypeptide.215.-. (canceled)16. A pharmaceutical composition for the treatment of an autoimmune disease , comprising a therapeutically effective amount of a terpolymer comprising three different amino acids randomly polymerized into a polypeptide , and a pharmaceutically acceptable carrier , wherein the three different amino acids are selected from the group of tyrosine , glutamic acid , alanine and lysine.1744.-. (canceled)45. A method for treating an autoimmune disease which comprises administering a therapeutically effective amount of a polypeptide consisting essentially of amino acids tyrosine , glutamic acid , alanine and lysine , wherein said autoimmune disease is not multiple sclerosis.46176.-. (canceled) The present application is a continuation of U.S. Ser. No. 12/231,292, filed Aug. 29, 2008 which is a continuation of U.S. Ser. No. 11/528,894, filed Sep. 27, 2006 which is a divisional 10 of U.S. ...
