Abstract: The invention is directed to methods of treatment of Alzheimer's disease and other tauopathies, via the administration of antibodies having specificity to abnormal forms of tau protein, the antibodies showing no binding and/or reactivity to a normal tau protein and being administered under conditions and in amounts effective to prevent or treat Alzheimer's disease or other tauopathies. In certain embodiments, the antibodies are selective for soluble truncated tau protein truncated at (i) its C-terminus after the glutamic acid residue Glu391, or (ii) at the aspartic acid residue Asp421, or (iii) at its N-terminus at the aspartic acid residue Asp13, or (iv) a combination of (i)-(iii). Further aspects of the invention are directed to the administration of an immunogen comprising an abnormal tau, preferably a soluble truncated tau.

Abstract: Antibodies selective for pathological tau dimers and/or prefibrillar pathological tau oligomers, immunogenic peptides and epitopes of these antibodies, hydridomas producing these antibodies, uses of these antibodies, immunogenic peptides and epitopes in preparation of pharmaceutical compositions for the treatment of tauopathies, and uses of these antibodies, immunogenic peptides, epitopes and pharmaceutical compositions in the treatment of tauopathies are described. Also described are uses of these antibodies, immunogenic peptides, epitopes in diagnosis and monitoring of tauopathies.

Abstract: An antibody capable of recognizing amyloid ? while not recognizing amyloid ? precursor proteins, and a method for using the same. A monoclonal antibody characterized by being capable of recognizing the N-terminus peptide of amyloid ? while not recognizing amyloid ? precursor proteins, an amyloid ? assay kit, a therapeutic agent of Alzheimer's disease, and a method for treating Alzheimer's disease using the monoclonal antibody.

Abstract: The invention relates to methods of treating a subject having Alzheimer's Disease, comprising the step of administering an antibody molecule which is targeted to ? amyloid peptide or to fragment thereof. In another embodiment the invention relates to methods of treating a disease or a disorder, characterized by amyloid beta deposition. In another embodiment, the invention relates to an antibody molecule, which is free end-specific for the N-terminus or the C-terminus of an amyloid ? peptide and to a pharmaceutical composition thereof. In another embodiment, the invention relates to an antibody molecule, which is targeted to the free C or N-terminus of a N-and/or C-terminus truncated amyloid ? peptide fragment.

Abstract: The invention provides a chimeric peptide or mixture of chimeric peptides that can be formulated as an immunizing composition and used in a method for immunization of a mammal against an internal peptide cleavage product derived from a precursor or mature protein, for which the peptide cleavage product and the precursor or mature protein are self molecules. The chimeric peptide or peptides have an end-specific B cell epitope from a naturally-occurring internal peptide cleavage product of a precursor or mature protein, as a free N- or C-terminus, fused with or without spacer residues to a T helper cell epitope derived from a living source different from that of the internal peptide cleavage product.

Abstract: An antibody capable of recognizing amyloid ? while not recognizing amyloid ? precursor proteins, and a method for using the same. A monoclonal antibody characterized by being capable of recognizing the N-terminus peptide of amyloid ? while not recognizing amyloid ? precursor proteins, an amyloid ? assay kit, a therapeutic agent of Alzheimer's disease, and a method for treating Alzheimer's disease using the monoclonal antibody.

Abstract: DNA encoding a recombinant antibody molecule end-specific for an amyloid-beta peptide, pharmaceutical compositions thereof, and a method for preventing or inhibiting progression of Alzheimer's Disease by introducing such a DNA molecule into brain cells to express the recombinant antibody molecule and prevent the accumulation of amyloid-beta peptides in the cerebrospinal fluid.

Abstract: Substantially pure 3-(3-indolyl)propionic acid free acid is synthesized by converting the free acid to 3-(3-indolyl)propionic acid calcium salt (3-IPA calcium), precipitating and washing, and then reconverting the 3-IPA calcium to the free acid. 3-IPA calcium is suitable for use in pharmaceutical compositions in tablet and sustained-release dosage forms. 3-IPA calcium can be used to inhibit the cytotoxic effects of amyloid beta protein on cells, to treat fibrillogenic diseases in a mammal, and to treat diseases or conditions in which free radicals or oxidative stress plays a role.
