The granted patent US12071631B2 describes an innovative adenoviral vector designed for gene therapy applications. Central to this invention is a repressible Major Late Promoter (MLP) that regulates the transcription of multiple adenoviral late genes. The MLP includes specific repressor elements, and its nucleotide sequence is defined in the patent. The vector can also incorporate adenoviral early genes and a transgene, which may encode therapeutic polypeptides, virus proteins, or proteins that can form virus-like particles. Notably, the transgene can include a Tripartite Leader (TPL) in its 5'-UTR, enhancing its expression. The patent further specifies potential transgene products, including Norovirus VP1, Hepatitis B HBSAG, and various AAV polypeptides.

Additionally, the patent outlines a process for producing transgene products by infecting mammalian cells with the adenoviral vector, culturing the cells, and isolating the expressed products. The adenoviral vector may also encode a repressor protein that binds to the repressor elements, with transcription controlled by the MLP. Other claims include the potential for the adenoviral vector to encode an adenovirus L4 100K protein, the insertion of transgenes within specific adenoviral regions, and the creation of compositions and kits that facilitate the use of the adenoviral vector. The patent also covers modified mammalian cells containing the adenoviral vector, indicating its utility in various biotechnological and therapeutic contexts.
