Abstract: The use of Apolipoprotein B, Apolipoprotein E, fragments and mimetics thereof is provided for diagnostic, detection, prognostic and therapeutic applications In prion diseases. More specifically, the invention provides the use of Apolipoprotein B or fragments thereof for modulating or identifying modulators of the prion protein replication which are implicated in the pathogenesis of transmissible spongiform encephalopathics and other prion diseases.

Abstract: Short peptides and derivatives or analogs thereof for the treatment or prevention of IAAP related disorders, in particular amyloid deposits associated with Type I or Type II diabetes are herein described.

Abstract: The present invention discloses peptides isolated from the extracellular domain of OX40 Ligand (OX40L) capable of binding OX40 Receptor (OX40R) and inhibiting OX40R-OX40L interaction. Such peptides, fusion proteins comprising them, as well as peptides and other molecules designed on their sequences, can be used as OX40R binding agents competing with natural OX40L for blocking OX40R-mediated cell signaling in the prophylaxis and/or treatment of diseases related to activated T cells.

Abstract: Provided are peptides comprising at least one azaamino acid and having ?-sheet breaking ability, useful in the treatment and prevention of diseases such as alzheimer's disease, Dementia Pugilistica (including head trauma), Hereditary Cerebral Haemorrhage with amyloidosis of the Dutch type (HCHWA-D) and Vascular Dementia with amyloid angiopathy.

Abstract: A highly sensitive method is provided for the detection of prions in a sample. These methods may be used to diagnose prion mediated transmissible spongiform encephalopathies such as bovine spongiform encephalopathy, Creutzfeldt-Jakob disease, scrapie, or chronic wasting disease. In particular a method for serial automated cyclic amplification of prion is disclosed. The method is both rapid and highly sensitive making it ideal for high throughput testing.

Abstract: The present invention provides peptide analogs and peptide mimetics that inhibit pleated sheet formation in amyloid ?-peptide, pharmaceutical compositions thereof and their therapeutic use. The inhibitory peptides possess activity as inhibitors in the formation of amyloid-like deposits and are useful in the treatment of Alzheimer's Disease.

Abstract: Short peptides and derivatives or analogs thereof for the treatment or prevention of transmissible spongiform encephalopathies, in particular CJD are herein described.

Abstract: A method for the diagnosis or detection of conformational diseases by assaying for a marker (the pathogenic conformer) of such diseases in a sample is described, which method comprises a cyclic amplification system to increase the levels of the pathogenic conformer which causes such diseases. In particular, such transmissible conformational diseases may be prion encephalopathies. Assays, diagnostic kits and apparatus based on such methods are also disclosed.

Abstract: The present invention is an inhibitory peptide capable of inhibiting &bgr; pleated sheet formation in amyloid &bgr;-peptide. The inhibitory peptide is a &bgr;sheet breaker peptide analog designed by chemical modification of a &bgr;sheet breaker peptide capable of inhibiting &bgr; pleated sheet formation in amyloid &bgr;-peptide.

Abstract: The present invention provides peptide analogs and peptide mimetics that inhibit pleated sheet formation in amyloid &bgr;-peptide, pharmaceutical compositions thereof and their therapeutic use. The inhibitory peptides possess activity as inhibitors in the formation of amyloid-like deposits and are useful in the treatment of Alzheimer's Disease.

Abstract: Novel peptides capable of interacting with a hydrophobic &bgr;-sheet forming cluster of amino acid residues on a protein or peptide for amyloid or amyloid-like deposit formation inhibit and structurally block the abnormal folding of proteins and peptides into amyloid or amyloid-like deposits and into pathological &bgr;-sheet-rich conformation as precursors thereof. Methods for preventing, treating or detecting disorders or diseases associated with amyloid-like fibril deposits, such as Alzheimer's disease and prion-related encephalopathies, are also provided.
