The present disclosure provides a chimeric non-human animal comprising human hepatocytes, methods for preparing the chimeric non-human animal comprising human hepatocytes and methods of utilizing the chimeric non-human animal comprising human hepatocytes to screening and identifying metabolites for any type of drugs, typically small molecule drugs, which might affect human liver functions and any other bodily function.

Human liver chimeric mouse with deficient P450 oxidoreductase

Embodiments of the disclosure include methods and compositions for treatment of a medical condition related to the liver, including at least viral infections and liver cancer, for example. In specific embodiments, immunotherapies are provided for delivering polynucleotides locally to the liver, wherein the polynucleotides encode particular gene products that include bispecific antibodies, including those that target certain liver antigens, for example.

Antibody based gene therapy with tissue-directed expression

Embodiments of the disclosure encompass immunotherapy for Hepatitis B viral (HBV) infection in an individual in need thereof. The immunotherapy comprises one or more chimeric antigen receptors (CAR) that target a HBV antigen, including CAR molecules that utilize specific scFv antibodies. In certain cases, the CAR comprises one or more mutations to reduce binding to Fc receptors. In specific aspects, cells that express the CAR(s) have reduced cytotoxicity that is safer and/or beneficial to individuals that are immunocompromised.
