Abstract: The invention provides a method for treating a medical condition, disease, or disorder mediated by a misfolded form of superoxide dismutase (SOD) in a subject in need of treatment. The method optionally comprises administering to the subject a composition comprising a pharmaceutically acceptable vehicle and an agent selected from (1) an exogenous antibody or fragment thereof that binds selectively to the misfolded form of SOD, and/or (2) an immunogen that elicits production of an endogenous antibody that binds selectively to the misfolded form of SOD, and/or (3) a nucleic acid sequence encoding (1) or (2). In certain embodiments, the invention provides methods of treating diseases such as Alzheimer's Disease, Parkinson's Disease or amyotrophic lateral sclerosis using amyotrophic disease-specific epitopes, and compositions including these epitopes. The invention also provides antibodies that bind to monomeric or misfolded SOD1, and not on the molecular surface of native homodimeric SOD1.

Abstract: A novel constrained peptide epitope derived from A?, related antibody compositions and methods of use. An isolated antibody that specifically binds to a cyclic peptide comprising the conformational epitope corresponding to a solvent-exposed, antibody accessible knuckle region of oligomeric A? is described.

Abstract: Human prion protein, PrP, selectively presents the epitope MDEYSNQNN (SEQ ID No. 14) when PrP misfolds. The misfolded form of human PrP is associated with various disease states. The present invention provides an antibody useful to detect and treat such diseases, including cancer such as ovarian cancer and lymphomas, and transmissible spongiform encephalopathies such as CJD. Also provided is an immunoconjugate in which the antibody is conjugated with urease as cytotoxin.
