Viral vectors are provided for use as genetic immunotherapeutic agents, including preventive and therapeutic vaccines as well as compositions to enhance cellular immune responses and innate immune responses. The vectors are particularly useful for treating or preventing cancer and infectious diseases. The vectors include lentiviral vectors that encode one or more antigens, a combination of adjuvants, and optionally may encode one or more soluble and secreted checkpoint inhibitor molecules. The adjuvants include latent membrane protein 1 (LMP1) from Epstein Barr virus and a fusion protein including LMP1 with in which the intracytoplasmic domain has been replaced by human IPS1 or a variant thereof capable of activating the STING pathway. The vector-encoded sequences are codon optimized for human expression.

Viral vector constructs for expression of genetic adjuvants activating the STING pathway

The invention relates to nucleic acids, including lentiviral vectors and lentiviral vector particles, encoding at least one Hepatitis B virus (HBV) envelop surface of genotypes A and/or C antigen, at least one polymerase of genotypes A and/or C antigen, at least one HBX protein of genotypes A and/or C antigen, at least one HBV consensus core of genotypes A and/or C antigen, and at least one HBV consensus core MHCI and MHCII epitopes of genotypes A and/or C antigen. The invention encompasses these lentiviral vectors and lentiviral vector particles, methods of making the vectors, and their use, including medicinal uses. The lentiviral vectors and lentiviral vector particles are for use in administering to humans to induce immune responses against the HBV antigens.

Lentiviral vectors for expression of hepatitis B virus (HBV) antigens

The present invention relates to the insertion of an MHC class I, MHC Class II, or &#x3b2;2 microglobulin upstream promoter sequence into a lentiviral vector to increase viral titers. The invention encompasses these vectors, methods of making the vectors, and methods of using them, including medicinal uses.

Lentiviral vectors containing an MHC class I, MHC class II, or B2 microglobulin upstream promoter sequence

The present invention relates to the insertion of a promoter sequence from an MHC class I gene promoter into a lentiviral vector in order to direct the transcription of a transgene, which preferably encodes an immunogenic polypeptide to be expressed in a mammalian cell host, preferably APC (DCs). The invention encompasses these vectors, methods of making the vectors, and methods of using them, including medicinal uses.
