Abstract: The invention relates to therapy of HCV infection, and more particularly to combination therapy of HCV infection. The combination therapy comprises combination of a HCV E1 vaccine and an antiviral agent. In one aspect, the antiviral agent may be an interferon.

Abstract: The present invention is based on the finding that the envelope proteins of HCV induce a beneficial immune response in chronically HCV-infected chimpanzees. The immunization can preferentially be carried out using HCV envelope proteins in the form of particles which are produced in a detergent-assisted manner. The envelope proteins when presented as such to chronic HCV carriers are highly immunogenic and stimulate both the cellular and humoral immune response.

Abstract: The present invention relates to a monoclonal antibody which forms an immunological complex with a phosphorylated epitope of a particular subclass or form of phosphorylated tau protein without forming an immunological complex with (i) fetal tau or (ii) biopsy or autopsy derived brain material from patients having died or suffering from diseases in which neurofibrillary tangle (NFT) is not a pathological hallmark. The invention also relates to a process for diagnosing brain diseases involving monoclonal antibodies of the invention. The invention also relates to a region of the tau molecule which is specifically recognized by the monoclonal antibodies of the invention.
