    • The present invention provides an isolated population of cells containing an expressible nucleic acid encoding proinsulin containing a proinsulin cleavage site and a glucose-regulated expressible nucleic acid encoding a protease capable of cleaving the proinsuling cleavage site to produce insulin. The invention also provides an isolated population of cells which further express a hexosamine synthetic pathway enzyme. The invention additionally provides vectors containing an expressible nucleic acid encoding proinsulin containing a proinsulin cleavage site and a glucose-regulated expressible nucleic acid encoding a protease capable of cleaving the proinsulin cleavage site to produce insulin. The invention further provides a method of treating or preventing diabetes by implanting into an individual cells coexpressing proinsulin containing a proinsulin cleavage site and a glucose-regulated protease capable of cleaving the proinsulin cleavage site to produce insulin.
    • 本发明提供了一种分离的细胞群,其含有编码胰岛素原的可表达核酸,该核酸含有胰岛素原裂解位点和编码能够切割前胰岛素切割位点以产生胰岛素的蛋白酶的葡萄糖调节的可表达核酸。 本发明还提供了进一步表达己糖胺合成途径酶的分离的细胞群。 本发明另外提供含有编码胰岛素原的可表达核酸的载体,所述胰岛素原含有胰岛素原裂解位点和编码能够切割胰岛素原裂解位点以产生胰岛素的蛋白酶的葡萄糖调节的可表达核酸。 本发明进一步提供了一种通过植入个体共表达含有胰岛素原裂解位点的胰岛素原和能切割胰岛素原裂解位点以产生胰岛素的葡萄糖调节蛋白酶的细胞来治疗或预防糖尿病的方法。

    • The present invention is directed to polypeptides and peptides 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. Morever, 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 or peptides to the mammal.
    • 本发明涉及含有以线性阵列随机连接的至少三个氨基酸的多肽和肽; 其中所述三个氨基酸中的至少一个是芳族氨基酸,所述三个氨基酸中的至少一个是带电荷的氨基酸,并且至少一个氨基酸是脂族氨基酸。 在优选的实施方案中,多肽含有三个或四个以下氨基酸:酪氨酸,丙氨酸,谷氨酸或赖氨酸。 根据本发明,本发明的多肽与抗原呈递细胞,纯化的人淋巴细胞抗原(HLA)和/或共聚物1-特异性T细胞结合。 更重要的是,根据本发明,这些多肽可以配制成用于治疗自身免疫疾病的药物组合物。 本发明进一步考虑通过向哺乳动物施用药学有效量的本发明多肽或肽中的任何一种来治疗哺乳动物自身免疫性疾病的方法。
