The present invention relates to the preparation of non-human animals having chimeric livers, whereby some or substantially all of the hepatocytes present are human hepatocytes. It is based, at least in part, on the discovery that rats, tolerized in utero against human hepatocytes, were found to serve as long-term hosts for human hepatocytes introduced post-natally, and the introduced hepatocytes maintained their differentiated phenotype, as evidenced by continued production of human albumin.

The present invention further relates to the use of such animals as models of various liver diseases, including viral invention. Such embodiments are based on the discovery that transplanted human hepatocytes in chimeric livers were found to be susceptible to Hepatitis B virus and Hepatitis C virus infection.

Molecular complexes for targeting a gene encoding a secretory protein to a specific cell in vivo and obtaining secretion of the protein by the targeted cell are disclosed. An expressible gene encoding a desired secretory protein is complexed to a conjugate of a cell-specific binding agent and a gene-binding agent. The cell-specific binding agent is specific for a cellular surface structure which mediates internalization of ligands by endocytosis. An example is the asialoglycoprotein receptor of hepatocytes. The gene-binding agent is a compound such as a polycation which stably complexes the gene under extracellular conditions and releases the gene under intracellular conditions so that it can function within a cell. The molecular complex is stable and soluble in physiological fluids and can be used in gene therapy to selectively transfect cells in vivo to provide for production and secretion of a desired secretory protein.

Compositions and methods for the inhibition of viral replication are provided. In some embodiments, the compositions include a nucleic acid sequence that is identical to a region of the hepatitis C virus (HCV) genome. In other embodiments, the compositions may include a nucleic acid sequence that has at least about 45% to about 95% sequence identity to the native HCV sequence and that has a similar secondary and tertiary structure to the native HCV sequence. In other embodiments, the compositions may include a nucleic acid sequence that does not have significant sequence identity to the native HCV sequence and that has a similar secondary and tertiary structure to the native HCV sequence. Also provided are methods for the treatment of a patient having an HCV infection by administering one of the compositions described herein, and uses of the compositions described herein in the manufacture of a medicament for the inhibition of HCV replication.
