  • Patent number: 8444990
    Abstract: Anti-Her2 antibodies which induce apoptosis in Her2 expressing cells are disclosed. The antibodies are used to “tag” Her2 overexpressing tumors for elimination by the host immune system. Also disclosed are hybridoma cell lines producing the antibodies, methods for treating cancer using the antibodies, and pharmaceutical compositions.

  • Patent number: 8076449
    Abstract: The present invention relates to a pharmaceutical composition for the treatment and/or prevention of a neurodegenerative disease, comprising the following polypeptide shown in any of (a) to (c): (a) a polypeptide comprising the amino acid sequence represented by Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala-Pro-Ala-Gly-Ala-Ser-Arg-Leu-Leu-Leu-Leu-Thr-Gly-Glu-Ile-Asp-Leu-Pro (SEQ ID NO: 1); (b) a polypeptide comprising an amino acid sequence having a deletion, substitution, insertion, and/or addition of one or several amino acids in the amino acid sequence consisting of Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala-Pro-Ala-Gly-Ala-Ser-Arg-Leu-Leu-Leu-Leu-Thr-Gly-Glu-Ile-Asp-Leu-Pro (SEQ ID NO: 1), and having an activity that inhibits neuronal cell death associated with neurodegenerative disease; and (c) a modified polypeptide from the polypeptide (a) or (b), or a pharmaceutically acceptable salt thereof, as an effective ingredient.

  • Publication number: 20100279942
    Abstract: An object of the present invention is to provide an agent effective for the treatment and/or prevention of motor neuron disease such as amyotrophic lateral sclerosis (ALS). The present invention provides a therapeutic and/or preventive agent for motor neuron disease comprising the following oligopeptide shown in any of (a) to (c) or a pharmaceutically acceptable salt thereof as an active ingredient: (a) an oligopeptide consisting of the amino acid sequence represented by Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala (SEQ ID NO: 1); (b) an oligopeptide consisting of an amino acid sequence having a deletion, substitution, insertion, or addition of one or several amino acids in Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala (SEQ ID NO: 1), and having an activity that inhibits neuronal cell death caused by a mutant superoxide dismutase-1 gene; and (c) a modified oligopeptide from the oligopeptide (a) or (b).
