Patent number: 9353167Abstract: Provided are methods of generating an immune response to an antigen. The method comprises priming an individual by administering an expression vector encoding the antigen. The vector comprises a transcription unit encoding a secretable fusion protein, the fusion protein containing an antigen and CD40 ligand. Administration of a fusion protein containing the antigen and CD40 ligand is used to enhance the immune response above that obtained by vector administration alone. The methods may be used to generate an immune response against cancer expressing a tumor antigen such as a mucin or human papilloma viral tumor antigen and to generate an immune response against an infectious agent. Also provided is a method for simultaneously producing the expression vector and the fusion protein.Type: GrantFiled: September 5, 2014Date of Patent: May 31, 2016Assignee: MicroVAX, LLCInventors: Albert B.

Patent number: 7252989Abstract: An adenoviral supervector system is disclosed that is capable of expressing more than 7.5 kilobases of heterologous DNA in a replication defective adenoviral vector. The supervector system comprises an adenoviral vector construct and a helper cell. The vector construct is capable of being replicated and packaged into a virion particle in the helper cell. In particular, the helper cell expresses DNA from the E2 region of the adenovirus 5 genome and complements deletions in that region in the vector construct. In certain embodiments, the disclosed invention comprises tissue specific expression of up to 30 kb of heterologous DNA directed by an adenoviral vector. Also disclosed are methods of transferring heterologous DNA into mammalian cells.Type: GrantFiled: April 4, 1994Date of Patent: August 7, 2007Assignee: Board of Regents, The University of Texas SystemInventors: Wei-Wei Zhang, Jack Roth

Patent number: 7109179Abstract: The present invention relates to the use of tumor suppressor genes in combination with a DNA damaging agent or factor for use in killing cells, and in particular cancerous cells. A tumor suppressor gene, p53, was delivered via a recombinant adenovirus-mediated gene transfer both in vitro and in vivo, in combination with a chemotherapeutic agent. Treated cells underwent apoptosis with specific DNA fragmentation. Direct injection of the p53-adenovirus construct into tumors subcutaneously, followed by intraperitoneal administration of a DNA damaging agent, cisplatin, induced massive apoptotic destruction of the tumors. The invention also provides for the clinical application of a regimen combining gene replacement using replication-deficient wild-type p53 adenovirus and DNA-damaging drugs for treatment of human cancer.Type: GrantFiled: February 23, 2004Date of Patent: September 19, 2006Assignee: Board of Regents, the University of Texas SystemInventors: Jack A.
