Cryptogenic cirrhosis: clinical characterization and risk factors for underlying disease.

Over the last three decades, virus-like particles (VLPs) have evolved to become a widely accepted technology, especially in the field of vaccinology. In fact, some VLP-based vaccines are currently used as commercial medical products, and other VLP-based products are at different stages of clinical study. Several remarkable advantages have been achieved in the development of VLPs as gene therapy tools and new nanomaterials. The analysis of published data reveals that at least 110 VLPs have been constructed from viruses belonging to 35 different families. This review therefore discusses the main principles in the cloning of viral structural genes, the relevant host systems and the purification procedures that have been developed. In addition, the methods that are used to characterize the structural integrity, stability, and components, including the encapsidated nucleic acids, of newly synthesized VLPs are analyzed. Moreover, some of the modifications that are required to construct VLP-based carriers of viral origin with defined properties are discussed, and examples are provided.

Construction and Characterization of Virus-Like Particles: A Review

The invention provides compositions and methods for treatment of amyloidogenic diseases. Such methods entail administering an agent that induces a beneficial immune response against an amyloid deposit in the patient. The methods are particularly useful for prophylactic and therapeutic treatment of Alzheimer's disease. In such methods, a suitable agent is Aβ peptide or an antibody thereto.

Prevention and treatment of amyloidogenic disease

Methods for identifying discrete monomer domains and immuno-domains with a desired property are provided. Methods for generating multimers from two or more selected discrete monomer domains are also provided, along with methods for identifying multimers possessing a desired property. Presentation systems are also provided which present the discrete monomer and/or immuno-domains, selected monomer and/or immuno-domains, multimers and/or selected multimers to allow their selection. Compositions, libraries and cells that express one or more library member, along with kits and integrated systems, are also included in the present invention.

Combinatorial libraries of monomer domains

The invention provides improves agents and methods for treatment of diseases associated with amyloid deposits of Aβ in the brain of a patient. Preferred agents include humanized antibodies.

Humanized antibodies that recognize beta amyloid peptide

Combining elements of biochemistry, molecular biology, and immunology, artificial DNA can be employed in a number of scientific disciplines. Some of the varied applications include site-specific mutagenesis, hybridization, amplification, protein engineering, anti-sense technology, DNA vaccines, protein vaccines, recombinant antibodies, screening fo

Artificial DNA :methods and applications

Hepatitis G virus co-infection in liver transplantation recipients with chronic hepatitis C and nonviral chronic liver disease.

Antigenic epitopes of hepatitis C virus (HCV) and mosaic HCV polypeptides useful as reagents in assays for the diagnosis or monitoring of HCV in a biological sample. The antigenic epitopes and mosaic polypeptides are also useful for the construction of immunogenic pharmaceutical compositions, such as vaccines. The mosaic polypeptides are artificial composite proteins constructed from diagnostically relevant antigenic regions derived from different HCV proteins. Preferably, the mosaic polypeptides contain antigenic epitopes from the core protein, NS3 protein, and NS4 protein. The preferred mosaic polypeptides optionally contain an additional antigenic epitope from either the NS4 protein or the NS5a protein or both.

Antigenic epitopes and mosaic polypeptides of hepatitis c virus proteins

A nucleic acid encoding a mosaic hepatitis E virus (HEV) polypeptide, consisting of the nucleotide sequence defined in the Sequence Listing as SEQ ID NO:1 is provided. A nucleic acid encoding epitopes 5, 6, 22, 23, 24, 28 and 29 of hepatitis E virus and substantially lacking the nucleic acids intervening the epitope-coding nucleic acids in the native hepatitis E virus is also provided. An isolated nucleic acid that selectively hybridizes under stringent conditions with the mosaic polypeptide-encoding nucleic acid and has at least 70 % sequence identity with SEQ ID NO:1 is provided. Also provided are such nucleic acids having at least 80 %, 90 % and 95 % sequence identity. A polypeptide consisting essentially of the amino acid sequence defined in the Sequence Listing as SEQ ID NO:2 is provided. Polypeptides encoded by the present selectively hybridizing nucleic acids, and nucleic acids encoding epitopes 5, 6, 22, 23, 24, 28 and 29 of HEV and substantially lacking the nucleic acids intervening the epitope-coding nucleic acids are also provided.

Mosaic polypeptide and methods for detecting the hepatitis e virus

The present provides immunogenic HAV peptides, antibodies and assays for detecting HAV. Vaccines against HAV are also provided.
