Abstract: The invention relates to polypeptides that comprise a portion of filamentous bacteriophage gene 3 protein (g3p) sufficient to bind to and/or disaggregate amyloid, e.g., the N1-N2 portion of g3p and mutants and fragments thereof wherein that g3p amino acid sequence has been modified through amino acid substitution to be substantially less immunogenic than the corresponding wild-type g3p amino acid sequence when used in vivo. The polypeptides of the invention retain their ability bind to and/or disaggregate amyloid. The invention relates furthermore to the use of these variant g3p-polypeptides in the treatment and/or prevention of diseases associated with misfolding or aggregation of amyloid.

Abstract: Provided herein, in one aspect, are antibodies that immunospecifically bind to a human KIT antigen comprising the fourth and/or fifth extracellular Ig-like domains (that is, D4 and/or D5 domains), polynucleotides comprising nucleotide sequences encoding such antibodies, and expression vectors and host cells for producing such antibodies. The antibodies can inhibit KIT activity, such as ligand-induced receptor phosphorylation. Also provided herein are kits and pharmaceutical compositions comprising antibodies that specifically bind to a KIT antigen, as well as methods of treating or managing a KIT-associated disorder or disease and methods of diagnosing a KIT-associated disorder or disease using the antibodies described herein.

Abstract: The present application relates to modified T cell epitopes derived from fungal ribotoxins, including a-sarcin, clavin, gigantin, mitogillin, and restrictocin, as well as modified ribotoxin molecules comprising one or more of the modified epitopes. The modified ribotoxin molecules inhibit protein synthesis, like the wild type ribotoxins, but exhibit reduced immunogenicity as compared to the corresponding wild type ribotoxin. Another aspect relates to a fusion protein which comprises a modified ribotoxin fused or conjugated or otherwise linked to a targeting molecule that is effective for binding a target of interest. Another aspect relates to the use of the modified ribotoxin or fusion protein for treating or managing a disease or condition.

Abstract: Humanized antibodies, capable of specific binding to human CEACAM1 molecules containing human-to-murine back-mutations in non-CDR variable regions, and their encoding polynucleotide sequences are provided. Pharmaceutical compositions comprising these antibodies as well as methods of their use in treating and diagnosing cancer and other conditions are also provided.

Abstract: Pseudomonas exotoxin A or “PE” is a 66 kD, highly potent, cytotoxic protein secreted by the bacterium Pseudomonas aeruginosa. Various forms of PE have been coupled to other proteins, such as antibodies, to generate therapeutically useful cytotoxin conjugates that selectively target cells of a desired phenotype (such as tumor cells). In the present invention, peptides spanning the sequence of an approximately 38 kD form of Pseudomonas exotoxin A protein were analyzed for the presence of immunogenic CD4+ T cell epitopes. Six immunogenic T cell epitopes were identified. Residues were identified within each epitope for introduction of targeted amino acid substitutions to reduce or prevent immunogenic T-cell responses in PE molecules which may be administered to a heterologous host.
