Patent number: 10597732Abstract: A method is presented for screening cells that produce allogeneic autophagosome enriched compositions able to induce expression of a selective marker on a subpopulation of peripheral blood mononuclear cells, the method comprising contacting a cell with a proteasome inhibitor, contacting the cell with a lysosome inhibitor, harvesting the resulting autophagosomes, determining a molecular signature of the harvested autophagosomes, and selecting cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes. By screening for cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes, enriched populations of autophagosomes may be generated which may illicit a specific immune response against numerous cancer types.Type: GrantFiled: February 21, 2018Date of Patent: March 24, 2020Assignees: UbiVac, LLC, Providence Health & Services-OregonInventors: Traci Hilton, Sandra Aung, Rieneke van de Ven, Christopher Paustian, Tarsem Moudgil, Christopher Dubay, Christopher Twitty, Hong-Ming Hu, Bernard A.

Patent number: 10226518Abstract: A method of inducing a specific immune response in a mammal, comprising: providing a first composition comprising isolated ubiquitinylated proteins in solution in the absence of membrane bound organelles, the isolated ubiquitinylated proteins comprising one or more specific antigens, and further comprising a threshold quantity of polyubiquitinylated short-lived proteins and polyubiquitinylated defective ribosomal products. The isolated ubiquitinylated proteins are affinity-purified from tumor-derived cells grown in culture, the tumor-derived cells being inhibited from degrading ubiquitinylated proteins via the proteasome while being grown in culture. In this way, highly immunogenic short-lived proteins and defective ribosomal products may be loaded onto dendritic cells for cross-presentation and priming of antigen-specific T cells restricted by either classical or non-classical MHC.Type: GrantFiled: October 10, 2014Date of Patent: March 12, 2019Assignees: UbiVac, LLC, Providence Health & Science—OregonInventors: Christopher Twitty, Erik LeShane, Bernard Fox, Hong-Ming Hu, Guangjie Yu
