Novel antibodies, methods and compositions for treatment of a disease which is susceptible to amelioration by the blocking of APP cleavage.

Methods and compositions with immune therapy for treatment of dementia

The invention relates to a filamentous bacteriophage, carrying bacterial Lipopolysaccharide (LPS) endotoxin on its surface, for use in treating cancer and in inhibiting angiogenesis, and in a different context, for use in promoting angiogenesis in diseases or conditions in which there is insufficient angiogenesis.

Filamentous bacteriophage as an angiogenesis modulator

The present invention is directed to a filamentous bacteriophage for use in treating a neurodegenerative tauopathy or susceptibility to a neurodegenerative tauopathy and a method of using the bacteriophage for reducing the formation of fibrils of tau protein or for disaggregating pre-formed fibrils of tau protein, such as in a patient suffering from neurodegenerative tauopathy. The filamentous bacteriophage used in the present invention does not display (i) a mammalian cell internalization signal (ii) a &#x3b2;-amyloid antigen or an antibody to &#x3b2;-amyloid, or (iii) a tau protein antigen or an antibody to tau protein.

Method for treating neurodegenerative tauopathy

The present invention is directed to an immunizing composition containing an antigenic product such as a multiple antigen peptide system (MAPS) or a filamentous bacteriophage displaying an A&#x3b2;PP epitope spanning the &#x3b2;-secretase cleavage site of A&#x3b2;PP and a method for inducing an immune response against the &#x3b2;-secretase cleavage site of A&#x3b2;PP using this immunizing composition. The present invention is also directed to antibodies against the &#x3b2;-secretase cleavage site of A&#x3b2;PP and their use in a method for inhibiting the formation of amyloid &#x3b2;.

Immunizing composition and method for inducing an immune response against the &#x3b2;-secretase cleavage site of amyloid precursor protein

Filamentous bacteriophage which does not display an antibody or a non-filamentous bacteriophage antigen on its surface is used to inhibit or treat brain inflammation associated with amyloid deposits and/or involving activated microglia, to inhibit the formation of amyloid deposits, and to disaggregate pre-formed amyloid deposits.

Method and filamentous phage for treating inflammation associated with amyloid deposits and brain inflammation involving activated microglia

Anti-A&#x3b2;P scFvs and single domain antibodies were generated, and when these antibodies were displayed on filamentous phage or as soluble protein molecules, stabilized by the maltose binding protein, they could prevent the fibrilization of A&#x3b2;p 1-40 and disaggregate A&#x3b2;p 1-40 fibrils generated in vitro. The anti-A&#x3b2;p scFv antibodies also stained amyloid neuritic plaques on slices from transgenic mice. The anti-A&#x3b2;P scFv and single domain antibodies can be used for inhibiting or treating Alzheimer's disease.

Single chain antibodies against &#x3b2;-amyloid peptide

Isolated polypeptides, isolated polynucleotides or expression vectors encoding same, viral display vehicles which can be specifically bind an exposed epitope shared by mutant, but not wild type, p53 protein are provided. Also provided are methods of inducing apoptosis and treating cancer as well as diagnosing a p53-related cancer using the isolated polypeptides uncovered by the present invention.

Human synthetic single-chain antibodies directed against the common epitope of mutant P53 and their uses

Anti-A&#x3b2;P scFvs and single domain antibodies were generated, and when these antibodies were displayed on filamentous phage or as soluble protein molecules, stabilized by the maltose binding protein, they could prevent the fibrilization of Abp 1-40 and disaggregate Abp 1-40 fibrils generated in vitro. The anti-A&#x3b2;p scFv antibodies also stained amyloid neuritic plaques on slices from transgenic mice. The anti-A&#x3b2;P scFv and single domain antibodies can be used for inhibiting or treating Alzheimer's disease.

Method for treating inflammation associated with amyloid deposits and brain inflammation involving activated microglia

Immunizing compostion and method for inducing an immune response against the beta-secretase cleavage site of amyloid precursor protein

More than 90% of mutations found in the p53 protein produce a conformational change in p53 which results in the exposure of an epitope, which is otherwise hidden in the hydrophobic core of the molecule. A single chain antibody (scFv) which specifically recognizes this common mutant epitope in mutant p53 but not in wild type p53 is disclosed. Also described are a DNA molecule encoding the scFv, pharmaceutical compositions comprising the antibody and methods of treatment using the pharmaceutical compositions.

Single chain antibody against mutant p53

A method of immunizing against plaque forming diseases using display technology is provided. The method utilize novel agents, or pharmaceutical compositions for vaccination against plaque forming diseases which rely upon presentation of an antigen or epitope on a display vehicle. The method further includes agents, or pharmaceutical compositions for vaccination against plaque forming diseases, which rely upon presentation of an antibody, or an active portion thereof, on a display vehicle. Whether antigens or antibodies are employed, disaggregation of plaques results from the immunization.

Bacteriophage displaying a&#x3b2; epitopes and method of use

A strategy for immunizing against amyloid plaques using display technology. The strategy includes methods, agents, and pharmaceutical compositions for vaccination against plaque forming diseases (e.g. Alzheimer's disease) which rely upon presentation of an antigen or epitope on a display vehicle. The strategy further includes methods, agents, and pharmaceutical compositions for vaccination against plaque forming diseases (e.g. Alzheimer's disease) which rely upon presentation of an antibody, or an active portion thereof, on a display vehicle. Whether antigens or antibodies are employed, desegregation of plaques results from the immunization.
