The invention provides an adenovirus or adenoviral vector characterized by comprising one or more particular nucleic acid sequences or one or more particular amino acid sequences, or portions thereof, pertaining to, for example, an adenoviral pIX protein, DNA polymerase protein, penton protein, hexon protein, and/or fiber protein.

Provided is a fusion protein, e.g., a cytokine receptor fusion protein, e.g., a TGF trap, with a novel linker sequence to permit the fusion protein to functionally optimally, e.g., to permit a cytokine receptor portion of a cytokine receptor fusion protein to bind optimally to its target cytokine. The fusion proteins, or expression vectors encoding for the fusion proteins, e.g., oncolytic adenoviral expression vectors, can be used to treat cell proliferative diseases and disorders, including certain forms of cancer and inflammatory disorders.

Aspects of the present disclosure include methods and compositions related to therapeutic immune cells having enhanced metabolic fitness. In certain aspects, polynucleotides encoding one or more viral, bacterial, and/or fungal genes capable of manipulating cell metabolism and, optionally, one or more antigen-specific receptors, are disclosed. In some aspects, disclosed are methods for enhancing the metabolic fitness of an immune cell comprising introducing into the immune cell a polynucleotide encoding one or more viral, bacterial, and/or fungal genes capable of manipulating cell metabolism. Cells (e.g., NK cells, T cells) expressing polynucleotides encoding one or more viral, bacterial, and/or fungal genes capable of manipulating cell metabolism and, optionally, one or more antigen-specific receptors are described. Also described are therapeutic methods using polynucleotides of the disclosure.

The invention provides an adenovirus or adenoviral vector characterized by comprising a nucleic acid sequence encoding one or more Respiratory Syncytial Virus (RSV) antigens and one or more particular nucleic acid sequences or one or more particular amino acid sequences, or portions thereof, pertaining to, for example, an adenoviral pIX protein, DNA polymerase protein, penton protein, hexon protein, and/or fiber protein, as well as a method of inducing an immune response against RSV in a mammal by administering the adenovirus or adenoviral vector to the mammal.

Disclosed are recombinant adenoviral compositions and methods for their use in treating disorders associated with epithelial tissues.
