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.

Chimeric antigen receptor therapy with reduced cytotoxicity for viral disease

A circular mRNA molecule possessing features resembling native mammalian mRNA demonstrates improved translation, while retaining the properties of an extremely long half-life inside cells. This circular mRNA is functional inside mammalian cells, being able to compete against native cellular mRNAs for the eukaryotic translation initiation machinery. The invention possesses additional RNA elements compared to a previous invention containing only an IRES element for successful in vitro or in vivo translation.
